Mixes multiple audio inputs into a single output.
Note that this filter only supports float samples (the @var{amerge}
and @var{pan} audio filters support many formats). If the @var{amix}
input has integer samples then @ref{aresample} will be automatically
inserted to perform the conversion to float samples.
For example
@example
ffmpeg -i INPUT1 -i INPUT2 -i INPUT3 -filter_complex amix=inputs=3:duration=first:dropout_transition=3 OUTPUT
