FireBrick Call Recording: Difference between revisions
|
If, when you play the files back through ''voip-answer'', they sound distorted, chances are you have either got the sample rate wrong, or else accidentally recorded them in stereo.
If you have a recording at a different sample rate, using Audacity, change the project's sample rate to 8000, then change the recording's sample rate to 8000, and then use the "Change Speed" effect on the recording — if the original rate was 44100Hz, apply a speed multiple of 5.50.
