audio cutting

[Ignus2]

Trim() refuses to cut audio-only clips.
Is there a plugin, which can cut audio, either sample based or frame based, if given fps?
(Or preferably both? :) )

try the avs cutter in megui.

Couldn't you just use blankclip and audiodub to attach video to the clips, and then trim them? You can then use audiodub again to attach the audio to a different video, or getchannels to return an audio-only clip, I think.

And how do I know the length of BlankClip to create?

[wonkey_monkey]

AudioLength(clip) will return the number of samples:


a=wavsource("...")
audiodub(blankclip(audiolength(a)),a)

Hello,At 41000 or 48000 samples per secound we have a whole lot of video frames being made. Not that there is anything wrong with that. Too many video frames will just be that, should not cause anything more than confusion.

if you would like the two to match a little closer try something like.
a=wavsource("...")
audiodub(blankclip((audiolength(a)/Audiorate(a))*yourfps),a)

audiolength(a)/Audiorate(a) = nSeconds of audio

sorry try this


a=wavsource("...")
audiodub(blankclip(length=int((audiolength(a)/audiorate(a))*yourfps),fps=yourfps),a)

audiolength(a)/Audiorate(a) = nSeconds of audio

This works, I tried it.

Function AudioTrim(clip aclip, int start, int end, float "fps") {
rate = Default(fps, 25.0) # or 23.976, 29.97
end = (end != 0) ? end : Round(AudioLengthF(aclip) * rate / Audiorate(aclip))
BlankClip(length=end, fps=rate)
AudioDub(aclip)
Trim(start, end)
KillVideo() # 2.5.7 feature
return last
}

end = (end != 0) ? end : Round(AudioLenghtF(aclip) * rate / Audiorate(aclip))Typo there. Should be AudioLengthF.

Oops! Ta! Fixed! :o

[Ignus2]

Good, it seems the only thing, that made this thread surface was the fact, that I didn't know about the existence of AudioLength(), AudioRate() and the like :)

(For others seeking this information, like me, it's documented here: http://avisynth.org/mediawiki/Clip_properties)

Thanks.

Thanks, that worked great! :thanks:
