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.
