Built for people who can hear the difference

●Bit-perfect, exclusively

Decaud can take your DAC for itself, so macOS can't resample your stream or mix other sounds into it. What's in the file is what reaches the hardware.

●Native DSD

DSD64, DSD128, and DSD256 delivered untouched over DoP to capable DACs, with transparent high-quality PCM conversion everywhere else.

●A signal path you can see

Every stage between file and device, laid out with a per-stage quality verdict. When something isn't bit-perfect, Decaud says so instead of hiding it.

●TrueHz analysis

Full-decode verification of each track's real quality. A "lossless" file that was made from a lossy master gets caught, not celebrated.

●Whole-house audio

Multi-room AirPlay in perfect sync, Sonos and DLNA casting, NAS/SMB and DLNA streaming including DSD, and an iPhone remote for the Mac library.

●A library that stays yours

Local-first files organized your way, serious tag editing with Discogs and MusicBrainz matching, bit-perfect CD ripping, and cue-sheet splitting, DSD included.

●Your music on every device

Import from a USB-C or SD drive on iPhone and iPad, straight into your own iCloud, or play in place right off the drive. Plug the same drive into your Mac and the songs are just there.

●A phone that knows your Mac

The iPhone Home screen picks up what the Mac is playing, one tap takes control: browse the Mac's library, queue songs, and drive playback from the couch.

Decaud is free

It's built by one person who thinks great sound shouldn't need a subscription. If it makes your music sound the way it should, you can keep it growing:
