Also, permanent result caching will be implemented.

Sounds good to me! Make sure that you'll store besides the filename also the size of the file as well as the modification date! I actually always preserve the timestamp when I edit some of my mp3's, like shorten them, remove the last bad frame, or change the id3 tags. EncSpot never updates this file because of that.

However, I mentioned something like this before. So when you get bored you probably want to go through some posts made in this thread just to make sure you didn't miss any suggestion

I can't wait for the new release though

btw.: I'm not sure how your program as going to determine the codec used, but I noticed that Lame uses silent frames to store its information. Some mp3's don't use Lame Headers at all, so the only thing EncSpot relies on are those silent frames. This works but not always though. Sometimes there are no silent frames at all, i.e. when you cut the mp3 file, but sometimes it is just naturally. EncSpot would always say that it was Gogo (after 3.x), which I found irritating. Your program was still able to guess the right codec though. Well not exactly, but it stated on both files (Lame Alt???). Therefore, I'm just curious how you plan to determine the right codec...I mixture between your first method and the method EncSpot uses would be probably perfect...

Thanks

=> would make a 5 min MP3 take around 35 KB / 10,000 MP3s about 350 MB

I think, for the average user 35kb of text for one mp3 would be a little much. Perhaps you could make it so that a user could define the level of verbosity desired when writing the cache??

It's not 35kb of text and it's not ment to be viewable by users. It's like that cache.dat file used by EncSpot. EncSpot uses cache data of about 1kb per file as it does not save a frame size table. A cached frame size table can speed up re-scanning on a version update aswell as it may speed up showing resync positions and other details.

Of course if you ment copying MP3's details in text form to clipboard, an option for choosing a verbosity level is a good thing. Thanks for that idea!

Just to inform you: It will take some more time to proceed as there's many other things which steal my time.

I got new PC components last weekend (updated from P3-600MHz to P4-2400MHz and bought some other things, too). As I killed my OS some days before I had to reinstall everything and still have to install some software, especially Delphi, so I guess the new version won't come earlier than in about two weeks.

No prob , even though my motives were wrong . . .

Thats too bad, , I look forward to seeing the next version when it is ready!

so, are you actually working on that program though? If you need the time, it is fine, but I just wanted to know about the status.
thanks

Wonderful work Feltzkrone. This will go far for sure if you don't mind everyone's input. Fantastic. EncSpot despite the bugs you have since reported in it's scanning system is still my most used mp3 utility apart from MP3Utility. Great work and I can't wait for the next version and so on...

Hi!

I didn't participate for a long period of time, but that's due to my time consuming job and the fact that the graphics card driver I used has crashed my system periodically (due to that there was no sense in working on the program as it crashed very often while typing in new sourcecode). Finally I updated the graphics card driver and everything works fine now.

If any of you know something about Delphi and free components, I'm still in search for good alternatives of...

TListView - I need column resorting capabilities (you know, drag'n'drop of colums should be able to be done by the user) and, if possible, shell integration so that one can drag and drop files here or open them in WinAmp or whatever. Also automatic items sorting (by clicking on a column header) would be wonderful

Directory Browser - yes, I've made on my own, but it still lacks in shell integration and efficient automatic updating

Basically, if you know of some free components fulfilling these criteria or if you can supply sourcecode on how to integrate shell menus (and add own menu items to it) etc. it would be very fine!

So far, just to let you know that the project isn't dead at all. Lots of shit is/was happening - that's the reason for the big delay.

BTW: I need a Listview/Treeview mixture component, too. This could be used for "opening" details for each mp3 item.

Take a look at shellshock, perhaps it is what you need. Not sure though.

hi, i read the topic first but not sure that you've seen this page from Encspot ..

http://guerillasoft.nstemp.com/EncSpot2/encoder.html

This page explain the Algorithm detection logic for encoder type detection and show clearly how it detect gogo one.. or not ..

it has been over a month now since the last update report So I wonder if someone is still working on this project and if there is an estimate release date. How about some BetaTesting?

thanks

You got a PM! And everybody else: Just wait some days!

And yes, my graphics card was f****ed up, which made software development imossible as my computer crashed nearly every hour. But that problem is solved now, I've got a replacement card one week ago and next week I'll have enough freetime to give further development a try...

great news :-) i was beginning to loose hope.

I do appreciate your work very much.... even in its pre-alpha-state i'm using your app regulary, and i if it becomes more accurate, even better

A nice feature would be, to also be able to see how good the reservoir is used in CBR-files - but i can wait for this - making the app more mature comes first

there seems to be a new program that will also allow to show the encoder. I think it will replace EncSpot and it is open source too

Take a look at this:

http://vbspot.sourceforge.net/

Yes, but I think not much users will use it as it is written in VB... There are several people here who think VB is evil.
Anyway, the main problem with VB is that programs created with it are not portable.

well, as for my part I don't give a crap! I use Windows and it will work fine on there, right? Do you any release date?

It shows a lot of info about the file, but not the encoder...

Yes, I know about that one. As you can see, the version I released is a pre-alpha. Alpha versions do not contain all features of the final version (and this is even a PRE alpha!). The problem is that I need to be sure that the current functions aren't buggy, as next features will rely on some of the values reported by now.
The GUI of the program will be totally different (will have the EncSpot style) and there will be a lot more features. In addition to EncSpot, VBSpot will support Ogg Vorbis files, too.

Anyway, I don't have any release date for the final version. I can't work on the project all the time, as I have to go to school, do homework, learn... At the moment, I also need to re-check the code and see if I can't get rid of some variables (there are a lot by now).

I hope Feltzkrone could help me out with some things, like extracting the side information of MP3 files. He sent me a part of his code once, but I have lost it due to a HDD crash.

A drag-n-drop feature in VBSpot would be nice...
BTW, I loaded an mp3 into VBSpot, and it reported "CRCs: True",
while WinAmp reports the opposite.

Same here...

Reply #121 – 2003-11-16 19:27:23

Yes, it is a known problem and is already fixed (no updated release, though). The problem was that for Original, Private, Copyright..., True has the value 1 and False is 0. For CRC it is the other way round - 0 means True and 1 means False. If you have the source code and a VB compiler, just edit:

blnMPEGCRC = CBool(lngMPEGCRC) to blnMPEGCRC = CBool(lngMPEGCRC = 0)

I have also fixed a bug with padding. For Layer I, padding is 4 bytes, not 1.

However, I am currently re-writing the code to fit the future plans and also trying to make it more compact, use less resources and work faster. I will also remove some of the comments as the actual code looks a bit cluttered.

Some of the MusePack support has been done already. I am waiting for Sebastian Andersson to make a GUI but I haven't seen him online for about three days (pretty unusual for a guy who is online 15 hours a day )

Yes, I have taken that in consideration.

By the way, it would be nice if someone with VB AND audio file knowledge would help.

Sebastian, as I've said before: If you really want to make progress with that project, I'd advice you to write at least the core in a language != VB.
