Aulosyne: Offline Music Player

Aulosyne is an offline music player for Android, made for people who actually own their music. No ads, no subscriptions, no trackers — just your local music library, playlists, podcasts, audiobooks, and sound.

Designed around local audio playback, Aulosyne focuses on the features that matter without clutter or distractions. Listen through headphones, Bluetooth speakers, a USB DAC, Chromecast, DLNA, or Android Auto while keeping your music front and centre.

Online features such as lyrics and Last.fm are completely optional and only connect if you enable them.

Aulosyne is built for people who prefer owning their music over renting it. Downloaded songs, ripped albums, podcasts, audiobooks, and your personal audio collection stay on your device.

Listen to music your way

Gapless playback keeps albums, live recordings, and continuous mixes flowing without unwanted pauses. Playback speed, sleep timers, and automatic bookmarks also make it useful for audiobooks, podcasts, lectures, and other long-form audio.

Smart Shuffle learns from how you listen, balancing familiar favourites with tracks you may not have heard recently. Browse and sort your library by genre or mood too.

Shape your sound

I've expanded the audio controls with Parametric EQ and AutoEQ. Fine-tune your sound, use profiles for supported headphones, save your own EQ profiles, or have them apply automatically by genre.

Experimental bit-perfect playback is also available for compatible USB DACs, giving supported devices a more direct USB audio path with minimal processing.

Edit your music files

The built-in tag editor lets you edit metadata and embed those changes directly into your audio files, helping you organise your music collection without a separate tag editor.

Lyrics when you want them

Find lyrics online or create your own. Edit and time synchronised lyrics, embed them into the audio file, or export them as an LRC file.

Cast your local music

I've added Chromecast and DLNA support, so you can cast music from your local library to compatible speakers, TVs, receivers, and other devices.

Made for your devices

Choose which Bluetooth headphones, speakers, or car audio devices should automatically start playback when connected. Android Auto lets you browse and play your local library while driving, with controls available from the widget and media notification.

Your player, your way

I've given the customisation system a major overhaul. Choose your own colours, use adaptive themes, customise navigation, switch between portrait and landscape layouts, or use a true AMOLED black theme. I've also added more languages and continued improving performance, especially with larger music libraries.

Privacy by default

Aulosyne does not track you, profile your listening habits, or interrupt your music with advertising. Online lyrics, Last.fm, and other internet-connected features are opt-in and are not required to use the app offline.

Built by Aretivo, an independent one-person studio focused on free, privacy-first Android apps.
