[Freeswitch-users] uuid_displace: change loudness level of audio

[Jeff Leung]

You may want to turn the audio file down by -20dB or so. You'd never want to
run full levels especially if you're playing back audio into the PSTN.

Hi Melanie,

If this is a wav file and the only purpose is to be played to callers then
your best bet is to change the volume on the file itself. That way you don't
waste CPU resources each time you play the file. 

Have you ever used the sox program?

Hi,

I want to use uuid_displace to play announcements while someone is
listening to music on hold.
This works fine, except that the music on hold is too loud - it should
be reduced when the uuid_displace takes place.
Is there a way to achieve this?
