Why use this distortion tool?
Creative sound design
Add grit, crunch, and overdrive to clean recordings for music production, podcast intros, game audio, and video sound effects.
Lo-fi and vintage effects
Create lo-fi, retro, and vintage-sounding audio by pushing the distortion to add warm saturation or aggressive clipping.
Private browser processing
Distortion processing happens locally in your browser. Your source audio stays on your device, never uploaded to external servers.
No plugins or DAW needed
Add distortion effects directly in your browser without installing audio plugins, VSTs, or a full digital audio workstation.
Common use cases
- •Add overdrive to a clean guitar recording for a heavier, more aggressive sound.
- •Create a distorted voice effect for podcast intros, trailers, or horror sound design.
- •Apply lo-fi crunch to music for vaporwave, chillhop, or retro aesthetic projects.
- •Distort sound effects for game audio, cinematic transitions, and trailer hits.
- •Create a walkie-talkie or radio transmission voice effect with moderate distortion.
Tips for better results
- •Start with low distortion values and increase gradually. A little distortion goes a long way, especially on voice recordings.
- •Combine distortion with a low-pass filter for classic lo-fi and vintage radio effects.
- •Export as WAV if you want to do more processing after applying distortion. Distorted audio encoded to MP3 may sound slightly different than the preview.
Audio distortion FAQ
What is the difference between distortion and overdrive?
Overdrive is a softer, warmer form of distortion that mimics the natural clipping of tube amplifiers. Higher distortion intensity pushes into harder clipping territory. This tool covers the full range from subtle overdrive to heavy distortion.
Can I create a lo-fi effect with this tool?
Yes. Use moderate distortion for warm saturation, then pair it with a low-pass filter to remove high frequencies. This combination creates the classic lo-fi, vintage audio aesthetic.
Is my audio uploaded to a server?
No. All distortion processing happens in your browser using FFmpeg WebAssembly. Your audio files stay on your device.
Can I undo the distortion after downloading?
Distortion is a destructive effect — once applied, the original clean audio cannot be recovered from the distorted file. Always keep a copy of your original file before applying distortion.
