Audacity File Size
Hello - I converted a 32-bit .wav file into a 16-bit .wav file and the size ballooned significantly. The file has to be tiny to be stored on a 2040 based board. Anyone have suggestions on how I can minimize the file size or why it gets so big ?

Re: Audacity File Size
Can you play back mono or stereo?
If you use the DAC of a microcontroller, ususally 22kHz with 8-bit PCM is more than enough, for voice even 11KHz will do. Try some of the bitrate options on saving as WAV. You can expect about 0.6-1.3 MB/minute that way.
