Direct answer
The downloader saves a progressive MP3 when SoundCloud exposes one. It does not re-encode audio to 320 kbps or improve the source stream. When a progressive MP3 is unavailable but a browser-readable AAC stream exists, it saves M4A instead of disguising that file as MP3.
What the current downloader actually does
- Progressive MP3 is preferred; AAC/M4A is the transparent fallback.
- The output bitrate and quality come from the available SoundCloud stream.
- The workflow handles one track URL; playlist URLs are sent to the playlist tool.
How the browser download works
- Paste a public SoundCloud track URL and fetch its metadata.
- Keep MP3 selected and start the browser download.
- Check the saved extension: it remains .mp3 or changes to .m4a when that is the real stream.
Known limits and failure cases
- Private, restricted, removed, or non-streamable tracks cannot be downloaded.
- A progressive MP3 is not guaranteed for every public track.
- Processing time depends on SoundCloud, track length, browser, and connection speed.
