Swinsian

Swinsian is a macOS‑only music player and library manager that handles a broad range of audio formats, including FLAC, MP3, AAC, ALAC, Ogg Vorbis, WMA, WAV, Opus, AIFF, MusePack, DSF and APE. It offers gapless playback, ReplayGain support, cue‑file handling, and automatic sample‑rate adjustment, allowing seamless listening across diverse collections.

The interface provides multiple navigation options such as an art grid, column browser and track inspector, all of which can be hidden for a minimal layout. Users can edit tags on multiple tracks simultaneously, employ regex‑based find‑and‑replace, and use a duplicate‑finder with flexible criteria to keep large libraries organized. Smart playlists, library statistics and a customizable desktop widget further aid management.

Playback controls include global keyboard shortcuts, a mini window, AirPlay support, last.fm scrobbling and AppleScript integration. Additional features such as folder watching, Apple Music library import, automatic album‑art fetching and a 10‑ or 31‑band graphic equalizer round out the application’s functionality.
