(i.e. would it be better to create more highly compressed speex files instead?) Specifically, I've been converting the mp3s to "wideband" 32k wav files, and then converting those wav files to speex using "speexenc" with the following settings: "--quality 10 --comp 10 --nframes 10".
Yes, this can have a negative effect on battery life, while I haven't tried that I would suggest you run some battery bench tests to make sure. On another note, it's crazy to go from mp3 to wav. Converting from an mp3 to wav does not magically restore the information that was missing in the mp3 file, the wav will only have the info that was on the mp3 and will result in quality loss.
