Produce mono audio by taking the mean of all audio channels.

Type:

(?id : string?, ?normalize : bool, pcm('a)) -> pcm(mono)

Arguments:

  • id (of type string?, which defaults to null): Force the value of the track ID.
  • normalize (of type bool, which defaults to true): Divide the output volume by the number of channels.
  • (unlabeled) (of type pcm('a)): Track whose mean should be computed.

track.audio.stereo​

Convert any pcm audio track into a stereo track.

Type:

(?id : string?, pcm('a)) -> pcm(stereo)

Arguments:

  • id (of type string?, which defaults to null): Force the value of the track ID.
  • (unlabeled) (of type pcm('a))

track.audio.swap​

Swap two channels of a stereo track.

Type:

(?id : string?, pcm(stereo)) -> pcm(stereo)

Arguments:

  • id (of type string?, which defaults to null): Force the value of the track ID.
  • (unlabeled) (of type pcm(stereo))

track.ffmpeg.decode.audio​

Decode a track content

Type:

(?id : string?, ffmpeg.copy('a)) -> pcm('b)

Arguments:

  • id (of type string?, which defaults to null): Force the value of the track ID.

track.ffmpeg.encode.audio​

Convert a track's content

Type:

(?id : string?, format(audio=pcm('a), 'b), pcm('a)) -> ffmpeg.copy('c)

Arguments:
