Just do a search for Winamp 5.1 Surround Edition in Google and that will turn up lots of places to download it from. Just used it to encode some movie music to 48k aacPlusv2 and it sounds fantastic. So much better than mp3pro. Winamp doesn't report the file info correctly, but it displays (and plays) fine in foobar 0.8.3 with the version of foo_input_std.dll I got from this thread (http://www.hydrogenaudio.org/forums/index.php?showtopic=26936&hl=pls) last year. Too bad the command line encoder (which is linked to in the first post) doesn't work for me. Would be especially cool if someone can make something similar to work with foobar 0.8.3, so one could transcode to aacPlusv2.

aacPlus is HE-AAC. HE-AAC is it's MPEG standard name, aacPlus is it's marketing name. aacPlus v2 is HE-AAC with Parametric Stereo in addition to SBR.

Yup, and this is what is in Winamp 5.1 Surround Edition. I like 96k Vorbis on my Karma, but I'm looking forward to when we start seeing aacPlusv2 in portable hardware players. Quality is more than good enough for this type of listening environment IMHO.

Ugg, ya beat me to the punch. 

Found out about 4 hours ago that Winamp now had AAC+ v2.  The bad news was that you could only rip CD's with it(so if you had music archived to Flac or something would be out of luck). 


Then got more good news coming here...

Thanks for plugin, errr wrapper.

When I played with the leaked version of Winamp 5.1 it allowed me to rip to those formats despite being a non-pro version. What was limited was the CD ripping speed (2x maximum). As far as I know, the non-pro version of Winamp has always allowed slow speed ripping to mp3, wma, and I think even aac too.

You can rip with Winamp to AAC+ v2 without upgrading to Pro.



You also can rip at higher than 2x now.

It lets you select 8x I think, but you're still limited to 2x when you go to actually rip. At least it's that way with the version I have.

causes aacenc to crash in win2k. HOWEVER, if you change "64000" to "48000" it works like a charm. Any other bitrate seems to crash it.

Parametric stereo works only when the bitrate is between 16 - 48 kb/s

So that´s why the mentioned program crashes with 64000, anyway you can check what options you can use in Winamp (ripping options) and thats are the only options you can use with the program (enc_aacplus.dll more precisely).

For example:

aacenc.exe "input.wav" "output.aac" "44100" "3" "128000" "1"

will encode the wav into 128 kb/s with Stereo Independent (the difference is "3" (SI), "5" (Dual Stereo), "4" (PS), "2" (Stereo), "1" (mono)


Anyway,
Parametric stereo is quite superb with the 48 kb/s. I just wonder, if there´s any trick how to enable PS in higher bitrates? That´d be the real MP3 killer  :-) 
I really like the sound of 48 kb/s with PS, but on the other side the quality of 96 kb/s with Stereo independent makes me uneasy (I don´t like the sound, and I don´t know why :-)

Post by: Ivan Dimkovic on 2005-09-02 09:18:25
Parametric stereo won't give quality improvements over certain bit rate - and for 44.1 kHz Stereo, this threshold is somewhere between 36-50 kbps, depedning on the material.

Above this, underlying encoder has enough bits to code stereo signal properly, and parametric stereo loses its efficiency because it cannot be switched on and off per frequency or - frame basis,  just for the entire file.

Ah, thanks! It works for me without crashing anymore. Now to figure out what app works best for transcoding APE files. I don't think foobar is going to work, I think it doesn't like the quotation mark requirements.

Edit: Ok, just tried it with in_ape.dll, worked fine. So far so good.

Hi,

there is a nice trick, how to make it :-)

From MP3 to AAC:
Just put to the directory, where´s the aacenc.exe the following file from winamp plugins directory: in_mp3.dll.

I´m sure, if you put "in_ape.dll", it will work  ;-)

for coding MP3 to AAC:

aacenc.exe "input.mp3" "output.aac" "44100" "4" "48000" "1"

That's not my problem, in_ape.dll works fine. It's the quotation mark requirement that foobar does not like. I'm going to experiment with [a href="http://members.home.nl/w.speek/multi.htm]multi frontend[/url] next.

Note! Original enc_aacplus.dll not included - you need to download Winamp 5.1 to get it!

Note! You need at least in_wave.dll (input winamp plugin) to encode WAV file (not included too)

Note! Tool was tested with in_wave.dll and in_mp3.dll only (but other formats may work too)

Ugh, looks like multi frontend is not the program I thought it was. Or at least, it doesn't work the way I thought it did. Maybe frontah might work? I just want a way to be able to transcode multiple ape files. That's not too much to ask I think, is it?

Don't use the quotation marks for the source and destination files, simply use the %s and %d arguments. foobar2000 will insert it's own quotation marks around the filenames. I just tested this and successfully converted a WavPack file (with spaces in the filename) to AAC.

Confirmed.  Works OK with filenames with no spaces as well.

It doesn't appear as though you can use tech fields in the parameter line.  Shame, otherwise you could use:

Code: [Select]
%s %d "%__samplerate%" "4" "48000" "1"


Edit: Ah, you can!  You just drop the "__"

Wow, thanks man! Now I can use foobar to transcode ape file to aacPlusv2 with wild abandon, WHEEE! 

Edit: Got some tag weirdness going on. Files made with foobar 0.8.3 + aacenc.exe have unreadable tags in The GodFather 0.70 and Winamp 5.1, but then again neither TGF or WA read file info right either regardless of whether Winamp or foobar made said file. For what it's worth, Winamp plays files created with foobar just fine (and vice versa). foobar is the only program that seems to be reading tag and file info correctly, regardless of where the file originated from.

Actually I have tags in these files with  no problem. 

I used Winamp to transcode, because I couldn't set the parameters up right in Foobar(tried without quotes and a couple other things, will try the above posted later). 

The way I transcoded from Winamp is use the plugin that the OP's was based off of.


BTW, if you do use the transcode plugin instead, make sure you choose Parametric stereo in the last drop down or you will get crash.

Working in Windows x64, I used the first version successfuly for converting from my tagged FLAC to 56 kbps channelmode2 stereo -- yes, channelmode 4 crashed. And, yes, the tag wasn't carried over.
Maybe there should be a separate thread split off into the Foobar2000 forum dealing expressly with parameters in batch instructions that can have Foobar2000 create the *.aac files while preserving tag info from FLAC or APE files. Oh, heck, I confess I'm no good at batch processing parameters (not now and not in DOS 3 days). So, please somebody, just post your line for foobar.
I had used Magix MP3 Maker 10 Deluxe to create files at 80 kbps, but I'm now convinced that was overkill for my Pocket Loox 720 -- I'd rather have 43% more music.
BTW, can anyone report whether Ahead Nero's encoder will duplicate the CT encoding engine of Winamp 5.1, or is it to include it's own optimizations? (Ivan, if you're looking, please include these transcoding with tag transfer abilities!)

No, this encoder only creats AAC stream, which can't have any tag at all, even it can't report its length correctly.

MP3Tag must have packed it into some kind of container.

Can you send me a small clip (few seconds is enough) encoded by this encoder and tagged by MP3Tag?

This is a bit of an oddity to me. When using Winamp to rip CD's to aacPlusv2 files, there are indeed tags added. Looks perhaps like maybe id3v1 and id3v2, I don't know for sure. The GodFather, Winamp, and Foobar all read these tags correctly, though those first two have trouble properly reading the files properties (reports as LC 22kHz mono). When transcoding APE files to aacPlusv2 using Foobar, I have no clue what tags it's putting into the AAC files, and both The GodFather and Winamp won't read them. I don't know much about AAC, but I'm guessing from your statement that there should not be tags in these files regardless of which program creates them. In which case, would putting the ACC file (which has no tags) into a container (such as M4A) be the right thing to do if one wants to have tags properly read by all programs?

When transcoding APE files to aacPlusv2 using Foobar, I have no clue what tags it's putting into the AAC files, and both The GodFather and Winamp won't read them. I don't know much about AAC, but I'm guessing from your statement that there should not be tags in these files regardless of which program creates them. In which case, would putting the ACC file (which has no tags) into a container (such as M4A) be the right thing to do if one wants to have tags properly read by all programs?

IIRC, Winamp apply mp4 extension for files it ripped, so those files already packed into MPEG4 container.

Using fb2k with this encoder (the CLI utility in this thread) only create AAC stream, AAC stream can't hold any metadata (correct me if I'm wrong), just raw audio data, so the stream have to be packed into some kind of container in order to have header (which hold track length... etc...) and metadata (title, genre... etc...)

No, I'm pretty sure the file extension is AAC. I'm in the midst of reinstalling stuff due to restoring an old backup, so I need to reinstall Winamp 5.1 to make sure.

Have any recommendations for an app that can take the raw AAC file and put it into a proper container that can contain tags that are properly readable?

Edit: Yup, file extensions are AAC. There is an option to turn off metadata tagging when ripping too. Probably is using ID3 when that option is on. Looks like properties are still displayed wrong too (except in foobar). Anyways, now have both Winamp and Foobar set to not apply any tags. Just need to figure out how to get the AAC into a container now, and then apply the proper tags afterwards.

For the people who wanted to put the AAC output files in an MPEG4 container, foobar2000 can do this. If you don't have the full install, download the MPEG4 Utilities (http://www.foobar2000.org/components.html#foo_mpeg4u) component (foo_mpeg4u). Add the AAC files to your playlist and select them all, then right click and click "MP4 Utilities" then "Convert to MP4 (same directory)". The AAC files are not deleted so you'll have to do that manually.

Edit: I should also note that the MP4 file is not bit identical to the source AAC file, but when extracted back out of the MPEG4 container is, which suggests the difference is due to a slight length offset. foobar2000 also detects the file in the MP4 container as LC AAC, but I believe it is still playing the HE AAC stream, as I couldn't hear any difference between the two. When it is removed from the MPEG4 container the AAC file is once again correctly detected as HE-AACv2.

foobar2000 0.9b8 detects the file in the MPEG4 container correctly as using SBR and PS.

Thanks, I didn't realize that because the option wasn't in my context menu for some reason. Gave it a try and Winamp, Foobar, and TheGodfather all have no problems with the tags of MP4/M4A files that Foobar creates from the tagless raw aacPlusv2 files. However, your right about Foobar 0.8.3 no longer displaying the files properties correctly anymore, but then the same problem still afflicts TheGodfather and Winamp as well (including the actual player display in Winamp now as well). Does sound like Winamp and Foobar are playing the aacPlusv2 stream contained in the container properly despite this failing though. I'm guessing since aacPlus hasn't made a big impact on the audio world yet, that all the audio and tagger apps out there that can currently handle AAC files, need to be updated to properly detect this newer profile. Nice to see Foobar on the forefront in regards to this with version 0.9. Hopefully other develpers will catch up soon now that Winamp has made this type of encoding available to the masses.

I just transcoded one of my favorite song from mp3 into a 32kbps AAC+v2, the sound is more satisfying than I expected, better than MP3PRO which I was onced very in favor of. I think AAC+v2 is simply the best for low-bitrate audio now.

Winamp plays the files I put into a mp4 container with foobar 0.8.3 as LC only here.

foobar 0.8.3 also has a hard time with one of the files I tested (transcoded Armand van Helden - Necessary Evil) putting out various errors...

Code: [Select]
ERROR (foo_input_std) : Gain control not yet implemented
ERROR (foo_input_std) : Maximum number of scalefactor bands exceeded
ERROR (foo_input_std) : Invalid number of channels
ERROR (foo_input_std) : MP4: decode error.

(all these appear by playing the file for some time/seeking around in it)


Also one of my files obviously sounds different (in foobar 0.9b8) when put into a mp4 container... they sound the same in foobar 0.8.3 (seems as if all files sound different. foo0.9 doesn't seem to like the raw AAC files. It does not only play the LC part, but maybe PS is missing?)

Intermezzo for AAC v2 stuff a bit.

Hmm...does anybody also having random errors popping up after clicking on 'Eject CD' on its Media Library when you already have your drive's tray out?
I think it starts spouting 'No CD' errors when I made the tray closed again with no CD on it.
[span style='font-size:8pt;line-height:100%'](well, in a dev's point of view, shouldn't it be one of the errors to be catched?)[/span]

Anybody here could reproduce the situation I'm getting?
I'm using Winamp 5.1, of course.


edit :
Oh crap, I didn't see where this thread is located at. =/
Anyway, to get this post on topic...

So, for now, which one's better to play aacPlus v2 w/ PS?
Using Winamp, fb2k 0.8.3, or fb2k 0.9bx?
Also, should it be contained in an MP4 or just let it in AAC in which Winamp produced?
This is, of course, considering u're making the AAC via Winamp's Media Library interface.

There is an in_mp4 for Winamp that could correct that problem.
Once you've installed it, mp4 files with aac+v2 content should play just fine.
Find it at http://www.free-codecs.com/download/MP4_In..._for_Winamp.htm (http://www.free-codecs.com/download/MP4_Input_Plugin_for_Winamp.htm)

BTW. Could the encoder posted in this thread be modified to take stuff from standard in (stdin) ?
Commandline could look like aanencplus - out.aac 48000 4 1
where "-" represents taking source from stdin.
A similar code adjustment can be found in the thread on this forum about the mp3enc from the helios open source mp3 encoder.
This would enable plugging in to dBpowerAmp convertor.

Just a stupid question.
I have a DivaGem MP3 player which also supports AAC.
I assume, that because the last firmware version supported AAC is about 1 year old, it will not support the latest Parametric stereo and will be playing without this new developed part? Am I right?

Anyway, what about current hardware players? Which of them support the latest improvement in AAC (ie Parametric stereo). The quality of Parametric stereo with 48 kb/s just amazes me, great quality to use in my car.

And there are some mobile phones capable playing AAC. Do they need to be upgraded to be able playing this new improvements (PS) or do they support it natively as PS is (probably?) the standard or some of them will play AAC files but just will not decode the PS?

Thanks

PS) sorry for my English :-)

0.9b8 doesn't seem to playback the raw AAC file correctly. As far as I can tell, it's turning the stereo stream into mono, probably by discarding one of the channels entirely.

Edit: I've examined the PCM output from 0.9b8, and it is a mono stream. Only the left channel is played back.

How are you easily adding the tags back? Since you are using tagless .aac files?  When you convert or rip are you just putting the tag info as filename then pulling it back out of that for your tags in the mp4/m4a container?

I never said I was doing it easily hehe. One option would certainly be to create file names that contain all the info (being careful of the 255 character limit for path names in Windows XP) and then regeneate tags from that (The GodFather is great at this). Foobar has a copy tag function, but it is always greyed out for me on APE files. Mp3Tag might work. It has an tag export/import feature that worked well for me in the past when I used to use MP3, but that was a very long time ago.

I was hoping you had figured out a simpler way to do it, guess I just assumed I didn't know some trick in Foobar that you might have known.

Parametric Stereo is technically compatible with variable bit rate streams. I don't know of any encoders that currently implement this however, and when I talked to Oliver at Coding Technologies he seemed quite surprised people wanted to use VBR for HE-AAC streams, saying "Which purpose would you use VBR for?". It seems unlikely, therefore, that we'll see VBR Parametric Stereo in the CT reference encoders for some time.

If you changed the extension to m4a (I believe iTunes and QuickTime don't like the mp4 extension) then it may be that the MPEG4 output file is not standard compliant. I don't personally have much experience with this particular foobar2000 component.

Of course the files are the same. I did not say this was not the case.

The normal extension for any MPEG-4 file is .mp4, which is also mentioned in the MPEG-4 standard. The .m4a file extension has been popularized by Apple, which started using the .m4a file extension in their iTunes software and iPod music players to distinguish between MPEG-4 Video and Audio files. Currently, most software that supports MPEG-4 Audio also supports the .m4a extension. The most common type of .m4a files available are those using the AAC (Advanced Audio Coding) audio format, but other formats such as Apple Lossless and even mp3 files may be put inside a .m4a container file. You can normally safely rename the file extension of a .mp4 file containing only audio to .m4a or vice versa to get the file to properly play in your favorite audio player.
http://en.wikipedia.org/wiki/MPEG-4_Part_3 (http://en.wikipedia.org/wiki/MPEG-4_Part_3)

From this snippet taken from Wikipedia, we see that some programs recognise .m4a while others recognise .mp4. I'm not an iTunes user but last I heard iTunes would not play files with an .mp4 extension.

I guess, the SBR part and the normal AAC part is already a kind of "relative" VBR. They might occupy various percent of a constant bitrate at a time. Just guess~

I figured out how to copy tags in foobar, and it's pretty simple. Load the source file and transcoded file into foobar. Click on the source file to select it, then click on the MP4/M4A file you made while holding down the control key. Both files should be highlighted in foobar. Now right click on them and go to Masstagger>Copy tags and that will do it. As far as I can tell it should work for multiple files as well, but I haven't tried doing that yet.

Edit: Yup, copying tags works great for a bunch of files. Just load the source files and transcoded files into a playlist. Make sure the order of the transcoded files in the list matches that of the source files in the list. Select them all, click on Masstagger>Copy tags and that should do it. Man, been using foobar forever and I still find new things to love about it.

Another edit: I just noticed the genre tag isn't getting copied over for some reason. foobar 0.9 Beta 8 does not have this problem, so that's now another reason to use it I guess (the other being proper reporting of AAC stream info regardless of whether it's in an M4A/MP4 container or not).

AACPlus (also known as HE AAC) is designed for low-bitrate quality, but is not designed for high quality. Use AAC, FLAC or another format for transparent and near-transparent audio.

AACPlus is for streaming Internet at low bitrates. AACPlus v1 is the base (HE AAC) and AACPlus v2 adds PS (Parametric Stereo) features. See the [a href="http://www.aacplus.net]http://www.aacplus.net[/url] website for more info about this interesting format.

It should sound better at 48k bps than MP3, MP3 Pro or plain AAC LC do at 48k bps. It is suggested to be used for 96k bps or less in all the docs I've read about it. For higher quality use AAC LC, MP3 or another format at 128k bps or better.

It is not designed to replace AAC and higher bitrate formats, but rather to fill the void for a good sounding, low-bitrate format for streaming or portable devices. I believe it is the best sounding (AACPlus v2 with PS) lossy codec at 48k bps there is currently out there in general use. We will need to wait for a listening test to confirm this, but based on all tests provided by Coding Technologies, it is better than the other low bitrate formats.

Many Internet streaming stations are using AACPlus streams now because of the good quality it provides at low bitrates. See http://www.tuner2.com/ (http://www.tuner2.com/) for a list of these AACPlus Internet radio stations.

Give it a try. I think you will be impressed at 48k (AACPlus v2 with PS) or 64k (AACPlus v1 without PS). It was designed to be better than MP3PRO at lower bitrates.

According to a recent listening test of various AACPlus encoders (at http://www.hydrogenaudio.org/forums/index....topic=36868&hl= (http://www.hydrogenaudio.org/forums/index.php?showtopic=36868&hl=) ), the Coding Technologies one used by WinAmp 5.1 and Real wins over the older Nero HE-AAC encoder version, although Ivan, one of Nero's developers is claiming a new v2 release of Nero HE-AAC to be coming in the next "few weeks".

Also in this listening test, AACPlus v1 at 64k (no PS) sounds a bit better quality than AACPlus v2 with PS. This is to be expected as to the more bits used in 64k over 48k. But 48k bps AACPlus v2 with PS is still a very good sounding codec for streaming audio.

I figured out how to copy tags in foobar, and it's pretty simple. Load the source file and transcoded file into foobar. Click on the source file to select it, then click on the MP4/M4A file you made while holding down the control key. Both files should be highlighted in foobar. Now right click on them and go to Masstagger>Copy tags and that will do it. As far as I can tell it should work for multiple files as well, but I haven't tried doing that yet.

Edit: Yup, copying tags works great for a bunch of files. Just load the source files and transcoded files into a playlist. Make sure the order of the transcoded files in the list matches that of the source files in the list. Select them all, click on Masstagger>Copy tags and that should do it. Man, been using foobar forever and I still find new things to love about it.

Another edit: I just noticed the genre tag isn't getting copied over for some reason. foobar 0.9 Beta 8 does not have this problem, so that's now another reason to use it I guess (the other being proper reporting of AAC stream info regardless of whether it's in an M4A/MP4 container or not).

Sorry for delayed response, been pretty busy past couple of days.  Thanks for getting back with me about the easier way to tag in Foobar.  I still hadn't got a chance to mess with it, will prob be sometime this weekend.

The foo_mpeg4u.dll only worked in foobar ver 0.83 here. offering the missing utf8api.dll error when loading attempted in the latest beta of foobar ver 0.9 .  In xmplay, indicated bitrate for 56 kbps files after conversion was 111kbps, as had happened using mp4creator.  Also, as with mp4creator. the file shrank significantly. I don't believe the AAC came through unharmed.
Has anyone posted a batch file with parameters for attempting this using mp4box? My commandline and batch skills have diminished appreciably since DOS passed ver 4.0 .

dimzon, even with pre-resampled (using SSRC) audio, such as for audiobooks or comedy records, I can't get your program to encode monaural 32000 Hz audio.

  I've tried both incarnations: the first, with *.dll support, allowed one to specify samplerate, and the second, without *.dll support, does not; unfortunately, neither produces an AAC file. Instead they give a message saying the audio must be 16-bit (it is) and that they are unable to find the file specified (it's there).

  Here are the command-lines I have tried:

Code: [Select]
aacEnc.exe "resample.wav" "resample.aac" "32000" "1" "12000" "0"


Code: [Select]
aacEncPlus.exe "resample.wav" "resample.aac" "12000" "1" "0"


  Is this a known glitch, or is there something else I might have overlooked?

FrzzMan said:
"MP3Tag must have packed it into some kind of container."
FrzzMan requested:
"Can you send me a small clip (few seconds is enough) encoded by this encoder and tagged by MP3Tag?"

I'm sorry not to have responded earlier, but when I saw that the tag info MP3tag pasted on didn't show up in foobar2000, I thought I must have been mistaken.  But today I noticed that Betaplayer for PocketPC -- a May build -- does read the tag info. (I noticed only because I'd had to rename for DOS different versions of Foghat's #1 hit; then I spotted that BetaPlayer wasn't reading the file name but the tag info that MP3tag had superimposed). Of course, it's only  on the Pocket Loox 720 that I care, since I prefer listening to FLAC files on the PC.
Anyway, send me a PM with a mail address and I'll send you a file.
Incidentally, I do notice that the Pocket Loox -- directly against my chest in a shirt pocket -- doesn't heat up with these files as it did when I used *.ogg.
BTW, I just see that Nero 7 arrives mid-October... Is that to be the general public's first opportunity to hear Ahead's AACPlus ? Ivan Dimkovic's postings had made it seem more imminent than that.

Hello, Mp3tag appends APEv2 (or ID3v1 depending on the option settings) tags to files with *.aac extensions, like foobar 0.8.3
The 0.9 version of foobar doesn't seem to support this anymore.

We have had HE-AAC support out for a few years already...

(aacPlus is just one brands' name for HE-AAC. Ours is called NeroDigital, but it is the same technology)

I think he meant to say aacPlusv2, aka HE-AAC+PS. I wouldn't mind knowing the answer as well.

Thanks Digisurfer... yes, that's what I meant.
I've another question for the golden eared here: what types of music will best test the tweaked AAC implementations at bit rates around 64 kbps?
I propose this 4/5 Yes reunion as being particularly telling: http://tinyurl.com/daucl (http://tinyurl.com/daucl) ; detail slipped and some vocals seemed muffled with the encoder in Winamp 5.1.  I'm suspecting that the SBR algorithms just cannot cope with allocating bits to music with so wide a frequency range at high energy.
What I'm getting at is whether the types of distortion, especially pre-echo, that are the enemy in MP3 are supplanted by new gremlins in max tweaked HE-AAC.
Still and all, I'm awed at the quality now attainable at these bit rates.  I remember being sceptical when Roberto said four years ago that he thought AAC would ultimately rule... but no longer!

YES !! This one can use stdin (thanks for all your effort) but the DOS window in which the coder runs doesn't seem to close automatically, that is, the encoder seems to get stuck at the endpoint when encoding from stdin.
Can anyone confirm this ?

Is there a quick and easy way to get the enc_aacplus.dll winamp plugin to work via the foobar diskwriter?  Not using Shoutcast, but just for the sake of batch encodes via foobar (and all of the nice DSPs) to AAC+PS files.

I'm trying to uninstall the Transcoder v0.5 from one of my Winamp 2.91 installations, it didn't work at all and now Winamp just freezes when it's trying to open.  It doesn't even display the whole skin before freezing.

What files should I remove?  Does it alter any existing files or registry values I should know about to remove/edit?

[edit] i rebooted and so far it seems to be ok, although i'm afraid to close winamp and try to reopen it.  i just removed the dll files and the exe. i'll update with an edit2 if it freezes again. [/edit]
