8-Bit Chiptune from Any Audio Track

The chiptune synth tracks ONE melody line and replays it with real NES/Dendy waveforms — pulse, triangle, noise, DPCM. Sounds clean on a solo vocal, whistled tune, or a single instrument. A full song with drums + bass + chords turns chaotic — isolate the vocal first.

How to Create Chiptune from Any Audio

1

Upload an audio file (MP3, WAV, FLAC, OGG, AAC, or M4A)

2

Choose a preset or select a wave shape (pulse, triangle, noise)

3

Adjust pitch smoothing, octave, filter, and noise level in real time

4

Download the chiptune version as WAV, MP3, or OGG

Transform any audio into authentic 8-bit chiptune with real NES 2A03 chip emulation

What You Get
  • Authentic 8-bit chiptune version of your audio
  • 9 ready-made presets — NES, Dendy, Game Boy, and more
  • Real-time preview before downloading
  • Download in WAV, MP3, or OGG format

Features

Authentic NES Waveforms
Real pulse waves (50%, 25%, 12.5% duty cycle), 32-step quantized triangle, and 15-bit LFSR noise — identical to the 2A03 sound chip in NES/Dendy consoles.
Real-Time Pitch Detection
YIN algorithm analyzes your audio 172 times per second, detecting melody and re-synthesizing it through chiptune waveforms. Hear changes instantly.
8 Sound Presets
NES Melody, NES Full, Dendy Bass, Game Boy, Chiptune Lead, 8-Bit Bass, Retro Noise, and Clean Square — each with unique waveform and filter settings.
Full Parameter Control
Adjust wave shape, noise level, pitch smoothing, octave shift, low-pass filter, and dry/wet mix. All changes apply in real time during playback.

Frequently asked questions

How does this chiptune synthesizer work?

The tool analyzes your audio's pitch using the YIN algorithm (172 times per second), then resynthesizes it using authentic NES/Dendy waveforms — pulse waves with variable duty cycle, 32-step quantized triangle, and 15-bit LFSR noise. This produces genuine chiptune sound, not just audio degradation.

What are the different wave shapes?

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.

Does it work with any music?

It works best with melodies, vocal lines, and simple arrangements where the pitch is clear. On complex polyphonic music (full band recordings), the synthesizer tracks the dominant pitch, which may jump between instruments. Use pitch smoothing to control transitions.

What audio formats are supported?

You can upload MP3, WAV, FLAC, OGG, AAC, and M4A files up to 50 MB. The converted result can be downloaded as WAV, MP3, or OGG.
