Lento: Slow, Reverb, Bass Boost — uboa

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!

Supported sites
- Spotify
- Apple Music
- YouTube
- YouTube Music
- Bandcamp
- Soundcloud
- TikTok

... and most other 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.
- Zen Browser: Spotify and other DRM-protected sites don't play reliably on Zen. This is likely a browser limitation, but I'll keep investigating.

This is a solo project, so issues will be addressed as time allows. Your patience is appreciated!
