Folks,
I am trying to format a file for a client for their music on hold. Their conversion spec is 8bit/8khz mono .wav (u-plaw).
I have been unsuccessful in having this sound reasonable after it goes into their AVIA phone system due to the GSM compression. I can get the converted file to sound reasonable, but once it's out of my hands and actually in the system it sounds like shit. I realize there is a good deal of degradation due to the GSM compression, but am at a loss what to do to improve the quality. Anyone have any experience with this and have any tips?
Thanks,
fritz
