I guess you mean like this:
Filter amix
Audio mixing.
Inputs:
dynamic (depending on the options)
Outputs:
#0: default (audio) [flt, fltp, dbl, dblp]
amix AVOptions:
inputs <int> ..F.A...... Number of inputs. (from 1 to
32767) (default 2)
duration <int> ..F.A...... How to determine the
end-of-stream. (from 0 to 2) (default longest)
longest 0 ..F.A...... Duration of longest input.
shortest 1 ..F.A...... Duration of shortest input.
first 2 ..F.A...... Duration of first input.
dropout_transition <float> ..F.A...... Transition time, in seconds, for
volume renormalization when an input stream ends. (from 0 to INT_MAX) (default
2)
weights <string> ..F.A....T. Set weight for each input.
(default "1 1")
normalize <boolean> ..F.A....T. Scale inputs (default true)
