Made for ear training
Guitar and piano solos become trivial to copy once they are half speed — but only if pitch does not drop an octave with them. ToneBrowser keeps the music in its original key while giving your hands time to catch up.
Speed Control — 0.25x to 3.0x, pitch stays put
YouTube ships seven fixed speeds and always couples speed to pitch. ToneBrowser gives 0.25x to 3.0x with 0.05 granularity, and leaves pitch untouched.
Language learning / shadowing
Listen to news at 0.75x to catch every consonant, then push to 1.25x for review. Pronunciation is preserved, so you are not training your ear on a distorted signal.
Podcasts and lectures
At 1.5x–2x the speaker still sounds natural. Hours of lectures finish without the usual chipmunk fatigue.
