Decaud is a music player for people who care how their files actually reach their ears. The name is the mission statement: DECent AUDio. It plays your library the way it was mastered: bit-perfect lossless, native DSD, and a signal path you can inspect at any moment, on hardware you choose. BUILT FOR SOUND • Bit-perfect playback with exclusive device access: Decaud takes the DAC for itself, so macOS can't resample or mix other audio into your stream • Native DSD over PCM (DoP): DSD64, DSD128, and DSD256 delivered untouched to capable DACs, with automatic high-quality PCM conversion everywhere else. Decaud asks before sending DoP to a new DAC, so a PCM only device never plays noise • Hi-res lossless: FLAC, ALAC, WAV, AIFF, DSF, DFF, APE, WavPack, and more, at any rate your hardware supports • Audio Unit plug-ins hosted right in the playback chain, exclusive mode included (Mac) • Gapless playback, optional crossfade, and headphone crossfeed with three classic presets • Dithered bit-depth reduction, ReplayGain, and a 10-band equalizer that works on AirPlay and live streams too, and tells you honestly when it's out of the path • A volume control that works even on DACs without a knob, exclusive mode included, without touching your samples (Mac) • Roon-style Signal Path: see every stage between the file and the device, with a quality verdict for the whole chain MORE WAYS TO LISTEN • Internet radio in real quality: Radio Paradise in FLAC, SomaFM, FIP, and your own stations, with live song titles and covers • Station: endless play seeded from any song, chosen from your own library by sound, no cloud involved • Classical browsing that understands works, movements, and composers, even on vinyl rips with messy tags • The waveform is the seek bar: scrub the track's real shape KNOW WHAT YOU'RE HEARING • TrueHz analysis decodes each track in full to verify its real quality: a "lossless" file that was made from a lossy master gets caught • Real-time analyzer, goniometer, phase and LUFS meters in a pop-out visualizer • Tempo, key, and tuning detection for every analyzed track YOUR LIBRARY, ANYWHERE IN THE HOUSE • Stream from NAS/SMB shares and DLNA servers, including DSD • Cast to AirPlay speakers in perfect multi-room sync, to Chromecast, and to Sonos and other DLNA renderers, with lossless delivery where the receiver allows it • Control your Mac library from your iPhone over the local network • iCloud sync keeps your library, ratings, and artwork on all your devices, in your own iCloud account A LIBRARY THAT STAYS YOURS • Local-first: your music lives in your files and folders, organized Artist/Album if you want Decaud to keep it tidy • Serious tagging: whole-album editing, Discogs and MusicBrainz matching, AcoustID identification by sound, and full DSF metadata editing • Bit-perfect CD ripping with error-corrected secure mode, and cue-sheet splitting, including bit-perfect DSD vinyl rips • Smart playlists with live rules, a watch folder that imports whatever you drop in, synced lyrics, compilations • Your listening history stays private, on your device, with optional export to a server you host PRIVATE BY DESIGN No account. No analytics. No tracking. Online metadata lookups (covers, lyrics, tags) are opt-in and send text or audio fingerprints only, never your audio. Decaud works completely offline. If you have a DAC and a folder full of music you actually own, Decaud was built for you.
