8-Bit Chiptune from Any Audio Track

The tool transcribes your audio into notes with a note-detection model, then voices those notes across the NES 2A03 channels — pulse waves for the melody, a 32-step triangle for the bass, and 15-bit LFSR noise for the drums. It builds a real arrangement, not just audio degraded to sound crunchy.

Pulse 50% (square wave) gives the classic NES melody sound. Pulse 25% is thinner and more nasal. Pulse 12.5% is very thin, like a Game Boy. Triangle produces a warm bass tone (NES bass channel). Noise uses a 15-bit LFSR for percussion and effects.

Yes — a full song works, not only a solo line. The tool finds the melody and puts it on the lead channel, with bass and drums on their own channels. Clear melodies come out cleanest; very dense or noisy mixes are harder. For an exact result, drop a MIDI file — its notes are already precise.

You can upload MP3, WAV, FLAC, OGG, AAC, and M4A files, or a MIDI file. The result downloads as WAV, MP3, or OGG. A MIDI is voiced straight across the chip channels from its own notes, with no conversion step.
