With VirtualDub or TMPGenc you can extract the sound as a wave file.

1.its mp2 I need, not wav
2.TMPGenc doesnt work with avi, only mpg, if Im not wrong
3.thanks anyway
 
Assuming you can get the WAV from an AVI (I think Sound Forge will
open AVI's but not save as MP2)... then you can encode to MP2 using
dbPowerAmp (get extra codecs for MP2) or the tooLAME command-line MP2
encoder.

Do web search for dbPowerAmp and tooLAME.

Curious why you "need" MP2? I "needed" MP2 because it what runs on
this Korg digital recorder I bought. MP3 does not work.
 
There is no mp2 to extract - You must encode an avi into an mp2 - do this
using tmpegenc

well the truth is like this:
I converted an avi to mpg with tmpgenc
but this mpg is silent, no audio at all
so I want to extract the audio from the original avi
to combine with the silent mpg, using tmpgenc
but it seems that tmpgenc only supports mp2 audio source

Tmpgenc can encode to mp2 direct from avi (specified in audio source), but
I have found that occasionally this doesn't work. So use Virtualdub to
demux the avi audio to .wav, then encode to .mp2 using that as the source
in Tmpgenc (or any other mp2 encoder), then multiplex in Tmpgenc "Mpeg
Tools"

As someone previously stated, TMPGenc *can* extract/convert avi audio
to mp2. Use "audio only" as the stream type. However, it seems that
something else is wrong if the mpg was silent and the avi it came from
wasn't. That can happen if you choose "System (video only)" as the
stream type during conversion. You should use "System (Video+Audio)"
as the stream type.

I am very certain I checked System (Video+Audio)
because I never touch the settings at all
and I converted other avi files the results are all fine
in both audio and video
 
Virtual dub is a free tool allowing you to extract the sound from an AVI
file and save it as a WAV.
You can then use tmpgenc to create an MPEG file using the original AVI as
video input and the WAV file as audio tracks.
Works fine for me.

do you mean under MPEG tools > simple multiplex > audio input
but when I click on my wav file, which is extracted by vdub-mod
it tells me "illegal MPEG audiostream"
so whats wrong here?

No, to make the mp2 you don't go into MPEG Tools. In the main window, in
select "Stream Type" ES (Audio only) and specify your wav file path in
"Audio Source". Go into Setting and configure (224kbps stereo is standard
for vcd/svcd). Run--this will convert the wav to mp2. Then you can go
into MPEG Tools and multiplex using the mpg file for video source and the
mp2 for audio. (Check as you go, of course--make sure the wav sounds ok,
then make sure the resulting mp2 sounds ok, you get the idea.)
