Lento: Slow, Reverb, Bass Boost

A small, no-nonsense extension to add slow, reverb, and bass boost effects on most music-streaming sites.

Head to a tab playing a music, choose your favorite preset (or dial in your own speed, reverb and bass boost), and sit back and enjoy! Lento supports most sites with audio or video. If it plays in a tab, Lento will probably catch it. Known limitations - Amazon Music: speed control only. Amazon DRM currently blocks the audio processing that the reverb and bass boost functionality require. This is a solo project, so issues will be addressed as time allows. Your patience is appreciated! Bugs and source code See a problem? Use the bug-report button right in the popup or file an issue on GitHub. Free, forever! Lento will always be free and open-source! You will never have to pay for features here. If you'd like to support my work anyway, check out my Ko-fi! Data disclaimer Lento will never transmit your data. All music processing is done locally on your machine, and nothing is ever sent to me or anyone else.
