AudioSplit[audio,t]

splits audio at time t.

AudioSplit[audio,{t1,t2,…}]

splits audio at times ti.

Details

  • AudioSplit can create audio partitions of different durations. Use AudioPartition to partition the audio signal into equal partition lengths.
  • The times ti can be any of the following:
  • ttime given in seconds
    Quantity[t,"unit"]time given in "unit" compatible with seconds
    Quantity[t,"Samples"]time given as number of samples

Basic Examples  (2)

Split an audio object at 0.5 seconds:

Wolfram Language code: AudioSplit[\!\(\*AudioBox["![Embedded Audio Player](audio://content-bfh9s)"]\), .5]

Specify a list of split points:

Wolfram Language code: AudioSplit[\!\(\*AudioBox["![Embedded Audio Player](audio://content-bfh9s)"]\), {.4, .8}]

Scope  (2)

Split an audio object at 1 second from the end:

Wolfram Language code: AudioSplit[\!\(\*AudioBox["![Embedded Audio Player](audio://content-bfh9s)"]\), -1]
Wolfram Language code: Duration /@ %

The time specification can also be expressed as a time Quantity:

Wolfram Language code: a = \!\(\*AudioBox["![Embedded Audio Player](audio://content-d31og)"]\);
Wolfram Language code: Duration /@ AudioSplit[a, Quantity[1, "Seconds"]]

Use a "Samples" Quantity:

Wolfram Language code: Duration /@ AudioSplit[a, Quantity[22050, "Samples"]]

Applications  (1)

Split an Audio object at the peaks of the "Novelty" measurement:

Wolfram Language code: a = \!\(\*AudioBox["![Embedded Audio Player](audio://content-bfh9s)"]\);

Compute the novelty and find the peaks:

Wolfram Language code: novelty = Rescale@AudioLocalMeasurements[a, "Novelty", PartitionGranularity -> {.02, .01}]; peaks = FindPeaks[novelty, 6, .001]["Times"]

Split the audio object:

Wolfram Language code: AudioSplit[a, peaks]

Properties & Relations  (1)

The list of split times is internally sorted:

Wolfram Language code: a = \!\(\*AudioBox["![Embedded Audio Player](audio://content-d31og)"]\);
Wolfram Language code: AudioSplit[a, {.8, 1.2}] == AudioSplit[a, {1.2, 0.8}]

Neat Examples  (1)

Split an Audio object and randomly recompose it:

Wolfram Language code: a = ExampleData[{"Audio", "Drums"}, "Audio"]
Wolfram Language code: dur = QuantityMagnitude@Duration@a;audioList = AudioSplit[a, Range[0, dur, dur / 32 ]];

Choose randomly from the list and join the result:

Wolfram Language code: AudioFade /@ RandomChoice[audioList, 40]//AudioJoin
