AudioPartition[audio,dur]

partitions an audio object into non-overlapping segments of duration dur.

AudioPartition[audio,dur,offset]

generates segments with specified offset.

Details and Options

  • AudioPartition returns a list of Audio objects.
  • AudioPartition[audio,dur,…] generates as many audio partitions of duration t as possible, padding incomplete segments at the end.
  • The specifications dur and offset can be any of the following:
  • durtime given in seconds
    Quantity[dur,"unit"]time given in "unit" compatible with seconds
    Quantity[dur,"Samples"]time given as number of samples
  • AudioPartition[audio,{dur}, …] can create up to duration dur segments.
  • AudioPartition accepts a Padding option. See the reference page for AudioPad for possible settings.

Basic Examples  (2)

Partition audio into non-overlapping, 1-second blocks:

Wolfram Language code: a = ExampleData[{"Audio", "Apollo11ReturnSafely"}, "Audio"]
Wolfram Language code: AudioPartition[a, 1]

Partition audio into overlapping blocks:

Wolfram Language code: a = ExampleData[{"Audio", "Apollo11ReturnSafely"}, "Audio"]
Wolfram Language code: AudioPlot[a]
Wolfram Language code: AudioPartition[a, 1, .5]
Wolfram Language code: AudioPlot[%]

Scope  (2)

Specify the number of samples in each segment:

Wolfram Language code: AudioLength /@ AudioPartition[AudioGenerator["Sin", 2], Quantity[15000, "Samples"]]

Specify the length of each segment, as well as the offset in number of samples:

Wolfram Language code: AudioLength /@ AudioPartition[AudioGenerator["Sin", 2], Quantity[15000, "Samples"], Quantity[5000, "Samples"]]

Options  (4)

Padding  (4)

By default, incomplete partitions are padded with zeros to have a length equal to other partitions:

Wolfram Language code: AudioPartition[AudioGenerator[{"Sin", 10}, 2.2], 1]//AudioPlot

Partition into equal-duration segments, dropping some samples at the end:

Wolfram Language code: AudioPartition[AudioGenerator[{"Sin", 10}, 2.2], 1, Padding -> None]//AudioPlot

Partition into unequal-duration blocks; no samples are dropped:

Wolfram Language code: Duration /@ AudioPartition[AudioGenerator["Sin", 2.2], {1}, Padding -> None]
Wolfram Language code: AudioPlot /@ AudioPartition[AudioGenerator[{"Sin", 10}, 2.2], {1}, Padding -> None]

Use "Periodic" padding:

Wolfram Language code: a = Audio[Range[10.], SampleRate -> 1]; AudioData /@ AudioPartition[a, 7, 7, Padding -> "Periodic"]
