How to upload music

There's a minimal CLI called netmdcli that I've written for testing, but the primary purpose of this library is to serve the Web MiniDisc project.

If you want to upload music to your device using the cli keep in mind that it won't parse your audio file container, but it works only with raw audio data.

ffmpeg will do the trick of extracting the raw data from your audio files for SP uploads. If you want to use LP2 or LP4 you'll also need atracdenc.

SP

ffmpeg -i youraudiofile -f s16be rawaudiodata.raw  # outputs raw audio data suitable for SP uploads

LP2

ffmpeg -i youraudiofile -ar 44100 youraudiofile.wav # 44100 16bit wav input file suitable for atracdenc
atracdenc -e atrac3 -i youraudiofile.wav -o youraudiofile.oma --bitrate 128
dd bs=96 skip=1 if=youraudiofile.oma of=rawaudiodata.raw # removes OMA file header

LP4

ffmpeg -i youraudiofile -ar 44100 youraudiofile.wav # 44100 16bit wav input file suitable for atracdenc
atracdenc -e atrac3 -i youraudiofile.wav -o youraudiofile.oma --bitrate 64
dd bs=96 skip=1 if=youraudiofile.oma of=rawaudiodata.raw # removes OMA file header

Then just run

netmdcli upload rawaudiodata.raw -f sp|lp2|lp4
