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.
