mux with uuid_displace: soundfile to loud
hi, we want to use uuid_displace with mux to playback a soundfile to a bridged uuid, so that this uuid can hear the other side talk AND hear the soundfile (whispering). is there an option we can set, for defining the loudness level of the soundfile? in our tests the soundfile was way to loud, so that it was nearly impossible to hear the other side talk, while the soundfile was playing. we tried "uuid_displace uuid start /path/to/soundfile/soundfile.wav 0 mux 0.3", so that the loudness of soundfile only would be 30% - but this does not work. thanks & kind regards dennis
I would pre-adjust the volume of the soundfile with sox instead of doing it real time. Mike On Jun 26, 2009, at 7:38 AM, Dennis wrote:

I have to agree with Mike here. Sox is awesome for this kind of thing and disk space is way more plentiful than CPU power. -MC
Are you playing a stereo file by chance? /b On Jun 26, 2009, at 12:46 PM, Michael Collins wrote:

thanks for your answers. i did not know, that muxing is cpu intensive. i just thought, that it would not matter, if one is muxing 50/50 or 30/70. for playing back a soundfile, while one can hear the other end it seems, that muxing is required. so the level of muxing should not make a difference!? anyway, if there is no other/better way, we have to do it with sox. no, we are not using stereo-files. kind regards dennis
Yes muxing like this will cause the volume to go up a little bit depending on the source input file. /b On Jun 29, 2009, at 7:30 AM, Dennis wrote:
