Bash script for batch uploading MP3s and FLACs into NetMD

md.sh

#!/bin/bash
# This script expects music files named ## Title.ext where ## is the track number.
ls *.mp3 *.flac | while read i; do
  ffmpeg -i "$i" out.wav < /dev/null
  # ATRAC3Tool can be found here: https://github.com/Treeki/atrac3tool
  wine ../atrac3tool.exe out.wav lp2.wav
  rm out.wav
  file=${i%%.*}
  title=${file:3}
  # linux-minidisc found here: https://github.com/Lana-chan/linux-minidisc
  sudo ../netmdcli send lp2.wav "$title"
  rm lp2.wav
done

when the script runs wine ../atrac3tool.exe ... I get the error message "atrac3 not found". What should I have to do?

you're missing the ACM codec, read the instructions in the readme of https://github.com/Lana-chan/linux-minidisc
