What is Distortion Effect?

Distortion Effect applies overdrive, fuzz, and clipping effects to audio using the Web Audio API's WaveShaperNode. Shape your sound from subtle warmth to aggressive distortion — privately on your device.

Under the hood, a WaveShaper curve remaps each audio sample through a non-linear function: soft clip rounds the peaks for warm tube-amp grit, hard clip slams them flat for fuzz-pedal aggression, the fuzz curve adds asymmetric germanium-style character, and bitcrush quantizes the signal for lo-fi 8-bit textures. A low-pass tone control rolls off harsh highs, an optional high-pass filter strips rumble and bass mud, and the normalize toggle scales the final render to 0 dBFS so the download stays loud without clipping the encoder.

How to use

1. Upload an audio file or use the built-in microphone input to capture live sound.
2. Adjust the distortion amount, curve type, and tone controls to shape the effect.
3. Preview the distorted audio in real time, then choose WAV, MP3, or OGG and download the processed file.

When to use

• Reamping a clean DI guitar take into the saturated tone you forgot to record.
• Adding gritty character to a flat-sounding vocal stem or synth bass line.
• Designing sound effects for games: weapons, engines, broken radio chatter.

Result

Upload a clean guitar recording, dial the distortion to 70% with a soft-clip curve, and download a warm overdrive version for your demo track.

FAQ

What's the difference between soft clip and hard clip?

Soft clip rounds the waveform peaks for warm, tube-style harmonics. Hard clip slices peaks off at a fixed level for the sharper bite of a fuzz pedal. Fuzz adds asymmetric germanium-style grit. Bitcrush quantizes the signal to fewer bit-depth steps for lo-fi, 8-bit, video-game character — a tonal world the other three curves can't reach.

Why does cranking the distortion amount make my audio quieter?

Heavy clipping squashes the dynamic range. The peaks no longer stick out, so the average level drops even though the signal sounds more aggressive. Flip on Normalize before download and the rendered file is scaled so its loudest point hits 0 dBFS — loud but clean. You can also boost the wet/dry mix back up.

Can I use this on a live microphone signal?

Yes — pick microphone as input source and the tool will route your live mic through the same WaveShaper chain. Latency depends on your audio driver, but most laptops stay under 30 ms.

Why does the processed audio sound buzzy or harsh on consonants?

Distortion exaggerates high-frequency content, and sibilants like S and T contain a lot of it. Pull the tone slider down to roll off the top end, or de-ess the source before distorting it.

What file format does the download produce?

WAV gives you a lossless 16-bit PCM file at the original sample rate, ideal for re-importing into a DAW. MP3 and OGG re-encode the result at 192 kbps for a much smaller file you can share. All three are produced locally on your device, never uploaded anywhere.
