AudioJoin

AudioJoin[audio1,audio2,…] or AudioJoin[{audio1,audio2,…}]

concatenates all audioi and returns an audio object.

AudioJoin[{audio1,t1},{audio2,t2},…]

inserts ti seconds of silence after each audioi.

Details and Options

  • In AudioJoin[{{audio1,t1},{audio2,t2},…}], if any of the ti are negative, audioi+1 overlaps audioi by ti seconds and the overlapped values are added.
  • All audioi are conformed to have the same data type, number of channels, and sample rate.
  • AudioJoin can take a SampleRate option to specify the sample rate of the resulting Audio object.

Examples

Basic Examples  (1)

Join audio objects:

Spectrogram of the joined signals:

Specify some silence between audio objects:

Spectrogram of the joined signals:

Scope  (4)

Control the separation between the Audio objects to be joined:

If a ti is negative, then audioi+1 will overlap with audioi:

Join audio objects with different types:

When joining audio objects with different sample rates, the larger sample rate is used:

Join audio objects with a different number of channels:

Options  (1)

SampleRate  (1)

By default, the largest sample rate of all audio is used:

Specify the sample rate:
