Simple web app that takes a Youtube video URL (or any URL supported by yt-dlp) and produces a downloadable audio file.

• playblack of audio in the browser with skip and speed controls
• mp3 files converted to Opus format on server-side and available immediately via streamed audio (no waiting for re-encode)
• previous downloads displayed on page, with customizable expiry to auto-remove old files
• supports SponsorBlock for removing sponsor segments in a video. Just add the -sponsorBlock command parameter. See yt-dlp doco for more details.

All command line parameters are optional.
