Recently updated
See what's new →- New
AudioTrick now has a What's New page — a public log of new tools, upgrades, and fixes, so you can see exactly what changed and when.
- Fixed
The Equalizer's presets — V-Shape, Vocal Clarity, Podcast and the rest — now apply the moment you select them, instead of leaving every band flat.
- Fixed
Volume Booster's normalize is more dependable — switching loudness presets quickly now settles on the target you picked last (Spotify, Apple Music, Podcast), and starting an export mid-normalize asks you to re-export instead of silently doing nothing.
- Improved
Vaporwave and Nightcore now preview the exact real-space reverb you'll hear in the downloaded file, and raising Nightcore's reverb fades in smoothly without a sudden jump in volume.
Why AudioTrick?
Most audio tools online are packed with ads, require signup, or upload your files to a server. AudioTrick is different — every tool runs entirely in your browser using the Web Audio API. Your files never leave your device, processing is instant, and everything is completely free. Drop a file, tweak the effect, and export. That's it.
Professional Audio Processing — in Your Browser
Free doesn't mean low quality. Every AudioTrick tool uses the same DSP techniques found in professional audio software.
Convolution Reverb
Real impulse responses from physical spaces — not cheap algorithmic reverb.
HRTF Spatial Audio
True 3D binaural processing for 8D audio — not stereo panning tricks.
Broadcast-Standard Loudness
EBU R128 peak limiting and LUFS normalization — the same targets Spotify and Apple Music use.
What You Hear = What You Get
Preview and export are bit-identical. No surprises when you download.
