Hi guys
 
I would like control the volume fade more precisely, namely specify a time period to perform the attenuation (as in the fade out case); use case :
 
^
|
|. . . . .                                     <---------- initial level sound
|         .
|          .
|           .
|            .
|             .
|              ................                <---------- final level sound
|
|
|
|----------------------------------------->
         ^     ^
         |--l--|
 
volume fading performed on l seconds
 
 
 
I founded only fade in/out in the sox documentation (fade to put the sound volume to 0 or 100%) ; is there a way to perform such a fading ?

Not with a single command, but you could probably achieve this with a
combination of commands including a mix with the original signal (sox -m).

In this regard, you can use the script crossfade.sh and crossfade_cat.sh
as examples on using the trim and fade to fade just a specific portion
of the file for a specific amount of time.
