// VAGDEMO2020 by Schnappy
// December 2020
// Based on VAGDEMO_FIXED by Yagotzirck
// Based on VAGDEMO by Shadow
// based on psyq/addons/sound/TUTO3.C

//
// Load two VAG file to SPU sound buffer and play them back alternatively or simultaneously.
//
// WAV creation: use ffmpeg to create a 16-bit ADPCM mono WAV file - change -ar to reduce filesize (and quality)
// $ ffmpeg -i input.mp3 -acodec pcm_s16le -ac 1 -ar 44100 output.wav
//
// WAV to VAG convertion using WAV2VAG : https://github.com/ColdSauce/psxsdk/blob/master/tools/wav2vag.c
// change -freq according to the -ar setting above
// $ wav2vag input.wav output.vag -sraw16 -freq=44100 (-L)
//
// Alternatively, you can use PsyQ VAGEDIT.EXE to change the sampling frequency of an existing VAG file.
