# Music Tools for Every Stage of the Creative Process
From the first rehearsal to the final mastering, every musician and producer needs precise tools available at any time. Our collection of online music utilities has been designed with one clear goal: maximum technical precision with minimum friction.No installation required. All tools run directly in your browser, are completely free and protect your privacy: no data leaves your device.# For the Practising Musician
The online metronome is the fundamental tool for any musician in training or in practice. Our metronome uses the Web Audio API to guarantee millisecond precision, eliminate drift and provide visual feedback with a ripple effect. The Tap Tempo feature lets you instantly find the BPM of any song.# For the Music Producer
The BPM to milliseconds calculator is essential in any mixing session. Syncing a delay or reverb to the song tempo makes the difference between a mix that breathes and one that sounds artificial. Similarly, the phase distance calculator aligns microphones with sample-level precision and prevents phase cancellation in multi-microphone recordings.# For the Sound Engineer
The frequency to musical note converter transforms any Hz value to its equivalent note, also showing the deviation in cents. Perfect for tuning analogue synthesisers, identifying problematic resonances in a room, or working with off-pitch samples. The digital audio storage calculator helps plan recording projects and manage disk space with precision.Technical Precision
All tools are based on mathematically verified algorithms. No approximations: results are exact and reproducible.
