@end example
@section amix
Mixes multiple audio inputs into a single output.
For example
@example
ffmpeg -i INPUT1 -i INPUT2 -i INPUT3 -filter_complex amix=inputs=3:duration=first:dropout_transition=3 OUTPUT
@end example
will mix 3 input audio streams to a single output with the same duration as the
first input and a dropout transition time of 3 seconds.
The filter accepts the following named parameters:
@table @option
@item inputs
Number of inputs. If unspecified, it defaults to 2.
@item duration
How to determine the end-of-stream.
@table @option
@item longest
Duration of longest input. (default)
@item shortest
Duration of shortest input.
@item first
Duration of first input.
@end table
@item dropout_transition
Transition time, in seconds, for volume renormalization when an input
stream ends. The default value is 2 seconds.
@end table
@section anull
Pass the audio source unchanged to the output.
