The only free, open-source Chrome extension that slows down browser audio in real-time with pitch preservation. Built on the Web Audio API using granular time-stretching — speech stays clear and natural at any speed, unlike the robotic output of native HTMLMediaElement.playbackRate resampling. Works on any browser media.
1400+ installs and 100+ active users. Built and maintained solo.
Looking for contributors. Vanilla JS + Web Audio API, no build step. Clone, load unpacked, and you're running in under a minute.
