Musicians

Musicians reach for this set for practice and prep, not production: tune up by ear with Guitar Tuner across a dozen alternate tunings, slow a recording down without changing its pitch with Slow Down Audio to work out a fast passage, and watch Audio Oscilloscope render a live waveform while checking mic levels before a take.

Your microphone audio and any file you load are analyzed locally in the browser — nothing is streamed out for tuning detection or waveform rendering, so an unreleased demo stays on your machine. No plugin install, no DAW licence, no account.
