@section asplit
Split input audio into several identical outputs.
The filter accepts a single parameter which specifies the number of outputs. If
unspecified, it defaults to 2.
For example:
@example
[in] asplit [out0][out1]
@end example
will create two separate outputs from the same input.
To create 3 or more outputs, you need to specify the number of
outputs, like in:
@example
[in] asplit=3 [out0][out1][out2]
@end example
@example
ffmpeg -i INPUT -filter_complex asplit=5 OUTPUT
@end example
will create 5 copies of the input audio.
