Free Audio & Music Tools
A practice room in your browser: a chromatic tuner that reads your mic to the cent, a pro metronome with time signatures and tap tempo, a BPM counter, a piano chord finder with real sound, a perfect-pitch trainer, a playable synth and a 16-step beat machine. Musicians, DJs, producers and teachers use these daily without installing a single app.
The utility side is just as strong — cut and fade audio files into ringtones with sample accuracy, generate pure test tones at any frequency to check speakers and hearing, translate and play Morse code, mix a synthesized rain-and-ocean soundscape for focus or sleep, identify the note a struck glass rings at, and even analyse the mains hum hidden in a recording.
Everything is powered by the Web Audio API, synthesized and analysed live on your device with no plugins and no downloads. Your microphone audio is processed locally and never recorded or uploaded — the tuner and pitch trainer listen, compute the note, show you the result and let the sound go. Nothing you play, sing or record ever leaves your machine.
Chromatic Tuner
Tune any instrument using your mic — see the note and cents in real time.
Pro Metronome
A precise metronome with time signatures, accents and a tap-tempo.
Tone & Frequency Generator

Audio Cutter & Ringtone Maker
Cut, trim and fade MP3, WAV or M4A files to make a ringtone or clip — sample-accurate, in your browser, never uploaded.
Piano Chord Finder & Identifier
Click notes on a playable piano to name any chord, or pick a chord to see and hear it — with inversions, scales and real in-browser sound.
Focus & Sleep Sound Mixer
Mix your own ambient soundscape — rain, ocean, fire, wind and noise, all synthesized live — with a sleep timer that fades out. Great for focus and sleep.
Morse Code Translator & Player
Translate text ↔ Morse and play it as audio, light or vibration.
BPM Tapper & Counter
Tap along to any song and instantly get its BPM. Great for DJs and producers.
Perfect Pitch Trainer
It plays a note — you sing or play it back, scored to the cent. Train your ear.
Beat Machine
A 16-step drum sequencer. Lay down a beat, tweak the tempo, loop it.
Hum Detective — Audio Forensics
Reads the invisible 50/60 Hz mains hum baked into any recording to reveal which power-grid region it was made in — and flags spliced edits. Forensics in your browser.
Knock to Tune
Tap a glass, mug or pipe and it names the note it rang at — plus a mode that tells you how much water to pour to tune a glass to any pitch.
Neon Synth Keyboard
A playable browser synth — keyboard or click, multiple waveforms and FX.
Audio & Music Tools — frequently asked questions
Browsers require one user tap before any page may play audio — it is an anti-annoyance rule, not a bug. After that first tap, every tool plays instantly.
No. The tuner, pitch trainer and analysis tools process your mic signal live on your device and discard it — nothing is recorded, stored or transmitted.
Yes — the tuner resolves pitch to the cent, the metronome is scheduled with the Web Audio clock (far more precise than JavaScript timers), and the tone generator produces mathematically pure frequencies.
