Decaud

Is your lossless actually lossless? Decaud decodes the whole file and shows you the spectrum. Hi-res and DSD playback. No account, no analytics, no tracking. Free.

Most players trust the label on the file. Decaud checks. It decodes each track in full and reads the real spectrum, so a "lossless" file made from a lossy master gets caught.

Decaud is a music player for people who care how their files actually reach their ears: hi-res lossless, DSD, and a signal path you can inspect at any moment.

KNOW WHAT YOU'RE HEARING • TrueHz analysis decodes each track in full to verify its real quality • The verdict lives on every row in your library • Real-time analyzer, goniometer, phase, and LUFS meters • Tempo, key, and tuning detection

BUILT FOR SOUND • An honest signal path: every stage between the file and the output, each with its own verdict • FLAC, ALAC, WAV, AIFF, DSF, DFF, APE, WavPack, and more • DSD plays through high-quality PCM conversion, labeled honestly in the signal path; TrueHz analyzes the DSD stream natively • Gapless playback, optional crossfade, and headphone crossfeed • Dithered bit-depth reduction, ReplayGain, and a 10-band equalizer

MORE WAYS TO LISTEN • Internet radio from Radio Paradise, SomaFM, FIP, and your own stations, with live titles and covers • Station creates an endless session from your own library, chosen locally by sound • Classical browsing understands works, movements, and composers • The waveform is the seek bar

ANYWHERE IN THE HOUSE • Stream from NAS and SMB shares and DLNA servers • Cast to AirPlay, Chromecast, 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 keeps your catalog, ratings, and artwork on your devices in your own account. Sending audio is always a separate, explicit action

A LIBRARY THAT STAYS YOURS • Import and play music you own • Serious tagging, Discogs and MusicBrainz matching, AcoustID identification, and DSF metadata • Smart playlists, synced lyrics, and compilations • Your listening history stays private, with optional export to a server you host

PRIVATE BY DESIGN No account. No analytics. No tracking. Online metadata lookups are opt-in and send text or audio fingerprints only, never your audio.

Decaud is free. No subscription, upgrade, or feature is behind a paywall.
