Converting wav files to ring tones
Once I figured out I could upload images to my cell phone using bitpim, the next step was making ring tones. A few google searches later, and I discovered pvconv. This software is a huge piece of junk. Closed source (but at least they do have a linux version), requires a few redhat only libs, and is horribly picky about the input file. This reminds me why opensource software kicks ass.
The worst part about this software is how peculiar it is about the format of the input wav file. After a few hours of messing with sox, I finally came up with this command
sox input.wav -r 8000 -w -t wav -c 1 output.wav
This seems to produce the correct output for converting to the pure voice format.
