Auralyn · in development
Auralyn is a desktop app for people who keep their own downloaded music. It gathers your files, folders and personal media servers into one library and plays them with care. It is in development, with a paid 1.0 planned for Mac first and Windows later.

Pre-release build with synthetic test music. The interface may change before 1.0.
Planned for 1.0
Each feature below works in the pre-release build on our Apple-silicon test Mac. We'll keep each limit listed until it's fixed.
Tags, covers, search, albums and artists, built from the folders you add.
Up to 100,000 songs and videos. The library rescans at launch or when you press Refresh; it does not watch folders. WMA and AVI files are not indexed yet.
One entry per song, with a choice of which copy plays.
Only byte-identical copies are merged automatically.
Correct titles, artists and covers, and import or export M3U and M3U8 playlists.
Edits live in Auralyn only. Exported playlists list local file paths.
Smart playlists, a mini player and a sleep timer.
A track that cannot play is skipped with a notice. Some smart playlists need listening history first.
Gapless album playback, crossfade from 0 to 12 seconds, volume leveling and a 10-band equalizer.
Gapless, crossfade and leveling apply only to local audio files up to 64 MiB. Gapless needs numbered tracks from the same album with shuffle off, and is not proven for every MP3 or AAC encoder. Leveling sets one fixed gain per track (it is not ReplayGain). The EQ affects Auralyn only.
Home mixes, song and artist radio, Autoplay similar songs, “Shape this session”, and more-like-this or less-like-this feedback.
Built from your own library on your Mac. Works without a network request or an AI model.
History drives your mixes and smart playlists.
On by default; you can pause or reset it. Plays are sent to your own Navidrome or Subsonic server only if you turn on scrobbling.
Time-synced lyrics from your own LRC files, plus artist and album pages built from your library.
Lyrics files you provide come first. When a song has none, Auralyn can find its lyrics online through LRCLIB; you can turn that off in Settings → Privacy. Online artist biographies and photos are optional and stay off until you turn them on.
Control Center, Now Playing and the Play/Pause key on your keyboard.
Checked so far on one Mac running macOS 27.
The background follows the album art, a graph traces loudness as the song plays, and a reduced-motion setting stops the movement.
The graph shows loudness, not a frequency spectrum.
Navidrome, Gonic, Jellyfin, Emby, WebDAV, and SMB network folders you have already mounted in macOS.
Each was tested against one version of that server with test music. Offline copies have been proven with test servers only.
Your media files are never uploaded.
Some online features: licence checks and updates, and optional lyrics and artist info.
In progress
Video playback and the release itself (a signed download, automatic updates and licences) are still in progress. Features join the list above only after they pass testing.
Files
Music: MP3, AAC (.m4a), Apple Lossless (ALAC), FLAC, WAV, AIFF, Opus and Ogg Vorbis.
Video: MP4, MOV, MKV and WebM, including AC-3 and E-AC-3 surround sound (Dolby Digital and Dolby Digital Plus), a choice of audio tracks, and text subtitles from the file or from a separate .srt, .vtt or .ass file.
Dolby, Dolby Digital and Dolby Digital Plus are trademarks of Dolby Laboratories. Auralyn is not made, endorsed or certified by Dolby.
So far tested only with short test files on one Mac. We'll publish a tested list after real files pass on the release build.
WMA and AVI files, DTS and TrueHD sound (those videos play without sound), picture subtitles such as PGS, and Apple Lossless in .caf files.
These are planned for updates after 1.0.
