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.

A bitcrusher damages the recording you already have; this one throws it away and plays the music again. A note-detection model transcribes the track into actual notes, and those notes are performed on real NES 2A03 voices — pulse waves at 50, 25 and 12.5 per cent duty, the 32-step triangle, the noise channel. That is why a piano line comes out sounding like a chiptune arrangement of the piano line, rather than like the same recording with the top taken off.
