Re-masters podcasts for bone-conduction swim headphones (OpenSwim, Shokz, etc.) by boosting speech clarity and evening out volume, so words stay intelligible over water and cap noise.
Conversion runs entirely in your browser — your audio file never leaves your device. Podcast/Spotify lookups fetch bytes through a tiny proxy (needed only because most feeds don't allow direct browser access), but the actual audio processing happens on your own hardware. Keep this tab open and in the foreground while a job runs. Best for files up to ~1.5GB.
Any audio format your browser's ffmpeg build can read: mp3, wav, m4a, flac, ogg, opus, aac, aiff.
No YouTube support here — extracting audio from YouTube needs server-side logic that can't run in a static browser app. Download the audio yourself (respecting YouTube's Terms of Service) and use Upload files instead.
