Find out how high you can hear with the new Hearing Test — a tone slowly rises in pitch from low to ultrasonic, and you tap (or hit Space) the moment it fades to read your highest audible frequency and a playful "hearing age." A 1 kHz reference tone checks your setup first, a short replay confirms your result, and you can test each ear separately, sweep the low end, or play the famous 17 kHz mosquito tone. Runs entirely in your browser, no signup.
- Improved
Every tool is now one click away from any page — a new Tools menu in the site header groups all audio tools by category (Effects, Speed & Pitch, Tuning, Edit, Convert, Generate), so you can jump straight from one tool to the next without going back to the homepage.
- New
Ringtone Maker is here — cut your favorite part of any song, smooth it with fade in and fade out, and export a ready-to-use ringtone. Pick how you'll install it and get the right file automatically — .m4r for iPhone via iTunes/Finder, or MP3 for Android and iOS 26 (which sets ringtones straight from the Files app, no computer needed).
- New
Convert MP3 to MIDI with AI — Spotify's Basic Pitch neural network transcribes your audio into notes entirely in your browser. Watch the result on a piano-roll preview, audition it with built-in playback, tune presets for piano, guitar or vocals with instant re-detection, and download a .mid file (pitch bends included) that opens in GarageBand, FL Studio or any DAW.
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.
