Project overview
The short version
Song Slower is a free audio editor that runs in the browser. It opens MP3, WAV, M4A, FLAC and OGG files up to 200 MB, depending on what your browser can decode, and lets you change speed and pitch independently and add reverb. Presets cover slowed + reverb, nightcore, lofi and a dry Practice mode that keeps the original key. You can compare the edit with the original, select a section and loop it, then export the full track or that section as MP3 at 128 to 320 kbps or as 16-bit WAV. The privacy policy says audio is read and processed on your device and is never uploaded, stored or received by the site. Cloudflare serves the pages, and Google Analytics loads only if you allow it. There's no account or signup.
