AVI De-Synth?

[frd1963]

Hello All.
Longtime AVISynth user, but first time poster.
I have used AviSynth to great success but have only scratched the surface of its capabilities, only having used it to feed AV apps multiplexed AV data.

My question is, would it be possible to use AviSynth to take an .avi and feed an audio application just the audio stream (ie mp3, wav, etc?)

I ask because I am a VJ/DJ have many music videos encoded for AV use, but then have also the associated mp3 files for use in audio only apps. It would be nice to be able to have a single library to use for either audio or AV use. I have read AVISynth's documentation and it doesn't appear that this was a consideration in its developement, understandably. Does anyone know of a way to do this with AVISynth or any other app?

To summarize: I am looking for an app that demultiplexes Audio from an AVI in realtime for use in a generic audio application.

Thanks in advance for any advice or comments,
-Frd

avisynth wont take in mp3 and output mp3, but it can take mp3 and output decoded PCM, which is probably what you'd want anyway for the veejaying thing.

i know adobe audition (cooledit by any other name...) can take avs files and extract the audio into it's multitrack. i imagine any decent video-enabled audio app could do similar.

as far as realtime stuff goes, perhaps look into graphedit and directshow plugins? i'm not really sure what specifically you're wanting to do with this (haven't done veejaying before, but what i've seen in melbourne's clubs seems more video intensive than audio... maybe i haven't seen the good stuff :))

Mug,

Thanks for the info. Actually, PCM audio (wav) would be fine, but I guess I guess my real problem is tricking the audio app into thinking that when it opens an AVS script, it is really just opening a wav file.

To clarify my intended use: I use AV apps to play (and manipulate music videos (avi files) but I also use audio files (wav, mp3, wma, etc) at other times in audio-only apps. Instead of having two sets of files, both containing full audio streams, I would rather be able to use the avi files for either purpose using an avs file for each video file, to serve the audio data to the audio app.

Thanks again,
-Frd

Frd,
As I understand you need 2 scripts - one for video+audio and one for audio only.

You'll need an uninvented yet "WavSynth" (http://forum.doom9.org/showthread.php?s=&threadid=56147) ,if that's the case.
