AudioChannelSeparate[audio]

gives a list of Audio objects, each of which represents one channel of audio.

AudioChannelSeparate[audio,channel]

returns the specified channel from audio.

Details

  • AudioChannelSeparate[audio] returns the separated audio in the form {audio1,audio2,…}.
  • The following channel specifications can be given:
  • Alla list of all audio channels
    nn^(th) channel
    {n1,n2,…}a list of audio channels n1, n2, …

Examples

open all close all

Basic Examples  (1)

Separate a stereo audio object:

Wolfram Language code: a = ExampleData[{"Audio", "DogBark"}, "Audio"]
Wolfram Language code: AudioChannelSeparate[a]

Verify that each signal has one channel only:

Wolfram Language code: AudioChannels /@ %

Scope  (3)

Separate a stereo in-memory audio object:

Wolfram Language code: a = ExampleData[{"Audio", "Bee"}, "Audio"]
Wolfram Language code: AudioChannelSeparate[a]

Separate a stereo out-of-core audio object:

Wolfram Language code: a = ExampleData[{"Audio", "Bee"}]
Wolfram Language code: AudioChannelSeparate[a]

Extract channels from a multichannel signal:

Wolfram Language code: a = AudioChannelCombine[AudioGenerator[{#, 2}]& /@ {"Sin", "Triangle", "Sawtooth", "Square"}]

Extract only the first channel:

Wolfram Language code: AudioChannelSeparate[a, 1]

Extract selected channels:

Wolfram Language code: AudioChannelSeparate[a, {2, 4}]

Extract all channels:

Wolfram Language code: AudioChannelSeparate[a, All]

Properties & Relations  (1)

AudioChannelCombine does the inverse operation of AudioChannelSeparate:

Wolfram Language code: a = ExampleData[{"Audio", "Piano"}, "Audio"]
Wolfram Language code: AudioChannelCombine[AudioChannelSeparate[a]]
Wolfram Language code: a === %
