Midi To Base64 -

base64 my_song.mid

is a text encoding scheme that converts binary data into ASCII characters (A–Z, a–z, 0–9, +, /, =).

with open('song_package.json', 'w') as out: json.dump(song_data, out) midi to base64

MIDI (Musical Instrument Digital Interface) is a binary file format ( .mid or .midi ) that stores musical performance data: notes, timing, tempo, instruments, etc.

Decode later:

with open('song_package.json') as f: data = json.load(f) midi_bytes = base64.b64decode(data['midi_base64']) with open('restored.mid', 'wb') as out: out.write(midi_bytes) If your MIDI is generated in memory (e.g., using midiutil or pretty_midi in Python), encode directly:

print(b64_string[:100]) # preview decoded_bytes = base64.b64decode(b64_string) with open('restored.mid', 'wb') as f: f.write(decoded_bytes) JavaScript (Node.js) const fs = require('fs'); const midiBuffer = fs.readFileSync('song.mid'); const base64String = midiBuffer.toString('base64'); base64 my_song

certutil -encode my_song.mid output.txt (Then remove the -----BEGIN CERTIFICATE----- lines manually.) Python (most common) import base64 Read MIDI file as binary with open('song.mid', 'rb') as f: midi_bytes = f.read() Encode to Base64 string b64_string = base64.b64encode(midi_bytes).decode('utf-8')
