If anyone else was curious and wanted to extract the samples to a usable format you can extract the contents with the repo linked in the article, convert with the other tool linked and finally convert from PCM to WAV with ffmpeg:

  node bin/extract-samples.js sf2ua

  for f in *.vox; do echo "Processing $f file.."; ./adpcm/adpcm od "$f" "$f.pcm"; ffmpeg -f s16le -ar 8000 -ac 1 -i "$f.pcm" -ar 44100 -ac 2 "$f.wav"; done
