Avisynth TimeStretch() 24 <-> 23.976

[ZenMystic]

I would like to slow an audio file I have down to 23.976 but have no idea how to use avisyth TimeStretch() command.... I found examples of speeding up.... But not slow down.... I want to go from 24.00 to 23.976 Can anyone show me how?

I don't use AviSynth for such things, but I suppose you saw the page where they have this:

TimeStretch(tempo = 25.0/(24000.0/1001.0)*100.0)

This will change the tempo from Film speed to PAL speed without changing the pitch.

So, to slow it down I suppose you'd do it like this:

TimeStretch(tempo = (24000.0/1001.0)/24.0*100.0)

I have no idea why you might want to do this, though. If for DVD it's not necessary.

If you're wanting to change the audio to match it up with an existing video it's probably better to change the video frame rate instead. That way there's no need to re-encode the audio and the frame rate can be changed without re-encoding.
