[Freeswitch-users] Dynamic volume adjustment in heterogenous IVR menus

[Michael Jerris]

The best way is to start with normalized sound files, then to use  
whatever features are available in your tts engine to send the right  
volume matched to the sound files.  That being said, a new media bug  
was just added in trunk for auto gain control and that might help, but  
I would never use it for this purpose.
