AAC without length and seek

I record AAC files from Internet Radio with StreamRipper (sourceforge).

Produced AAC have no time length and I cannot seek them with Foobar2000.

I tried to embed AAC inside a MKA container but MKVmerge failed to open *these* AAC.

Is there a loseless solution?

I guess your AAC file is HE-AAC? If this is the case then you must let mkvmerge know this too. Highlight the AAC track in mkvmerge and then check 'AAC is SBR/HE-AAC/AAC+' (look at the screenshot below).

No. MKVtoolnix (gui) cannot identify the stream at all.

More specific:
I record from this address: http ://160.79.128.61:7004/ with StreamRipper.
When I have a complete AAC song and open it with Foobar, it hasn't size and seek ability.

VLC player can seek the file but ti doesn't show the time length of file:  00:00:00/00:00:00.

Media Player Classic works fine. Seeks correct and displays curent time/time length correct.

Those are raw AAC. foobar2000 v0.9 can't seek or display real length, while v0.8.3 can.

You can mux those into mp4 container with YAMB to make correct m4a.

This is a small sample (60KBs).

YAMB does not work with these files.

I also didn't managed to convert his file using the latest yamb. The file is clearly loaded (and the log says so) but it's not visible in the window, so the properties cannot be set and the 'next' button is greyed.

But I did it from the command line:

Code: [Select]
D:\Install\Audio Codecs\UTILITIES\yamb>MP4Box.exe -add sample.aac:sbr sample.mp4
AAC import SBR (implicit) - sample rate 22050 - MPEG-2 audio - 1 channel
Converting to ISMA Audio-Video MP4 file...
Saving to sample.mp4: 0.500 secs Interleaving

oh!
Yes, it works!
Thanks!
I write a php script now, for mass convert!

Thanks for your time!

Btw: it seems MP4box is a little bit buggy (some crashes) but all songs mp4 work fine after that, so I am happy.
