You need SoX (http://sox.sourceforge.net) to convert audio files into raw format. Windows users: - New: SoX is already included in this library - Drag and drop your .WAV-files to the appropriate .bat files for conversion (in "Arduino with xx MHz" folder) - Converted files will go to folder "converted" Linux/Mac users: - Install SoX by compiling it from source or using your favourite package manager - use the following line for conversion: sox inputfile.wav --norm=-1 -e unsigned-integer -b 8 -r 31250 -c 1 -t raw outputfile.raw - For stereo change -c 1 to -c 2 - For full rate use -r 62500 @ 16MHz, -r 31250 @ 8 MHz - For half rate use -r 31250 @ 16MHz, -r 15625 @ 8 MHz - For 16-Bit playback (need two PWM outputs for every channel) change -b 8 to -b 16
