Filter to extract audio from an AVI?

Subject: Is there a filter to extract audio from an AVI file?

I use DV type-1 AVI files and as such if I want to use any software
which uses VFW I need to load the AVI via Avisynth.

My question is, is there a Filter (or any plans to write one?) which
can load audio along with video without having to extract the audio
into a WAV first ?

Perhaps I'm just dreaming but having to extract a Wav from an AVI first is a real pain. How do other people incorporate audio?

#I envisage it would work something like this if an audio extractor was available!

Video=DirectShowSource("Scene0001.avi",fps=25)
Audio=ExtractAudio("Scene0001.avi",fps=25)
Output=AudioDub(Video,Audio)
Return Output

I'm looking for the same type of filter. Is there one available?

do neither directshowsource nor avisource load the audio?

[frogster]

The idea is to remove the video and only have audio. sort of the like save wav feature in vdub.

You could convert the clip to type-2 DV (see the links thread (http://forum.doom9.org/showthread.php?s=&threadid=33519) at the DV forum and look for the ulead converter download link) and then use virtualdub to demux...

hi,

you can always use DirectShowSource filter to extract the audio stream from an AVI file

so your script became :

Video=DirectShowSource("Scene0001.avi",fps=25,audio=false)
Audio=DirectShowSource("Scene0001.avi",fps=25,video=false)
AudioDub(Video,Audio)

I think that you you can omit the

Output=...
Return Output

Why waste so many keystrokes?

DirectShowSource("Scene0001.avi",fps=25)

That gives you video and audio.

DirectShowSource("Scene0001.avi",video=false)

That gives you audio only.
