Creating the disk image

After compiling, you need to generate a disk image with mkpsxiso:

mkpsxiso -y isoconfig.xml

Using ffmpeg to generate a CDDA compliant Wav file

Needed Specification : RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, stereo 44100 Hz

Conversion

ffmpeg -i input.mp3 -acodec pcm_s16le -ac 2 -ar 44100 output.wav

ffmpeg -i herb.wav.new -filter_complex "[0:a][0:a]amerge=inputs=2[a]" -map "[a]" herbi.wav
