Redbook on FiiO R7 in a vintage hi-fi setup with floor-standing speakers

At home in any hi-fi setup.

There's something about putting a disc in a tray, hearing it spin up, and pressing play.

The warmth of a CD collection. Liner notes spread across your lap. The ritual of choosing what to listen to — not what an algorithm chose for you.

Redbook brings that ritual to your Android device. Pure, uncompressed, bit-perfect audio — exactly as the mastering engineer intended. 16 bits. 44,100 samples per second. The Red Book standard that defined digital music.

How It Works

01

Connect

Plug any USB CD or DVD drive into your Android device using a USB-C cable or OTG adapter.

02

Insert

Drop in an audio CD. Redbook reads the disc, identifies the album, and fetches the cover art.

03

Listen

Bit-perfect PCM audio streams directly from the disc to your ears. Zero compression. Zero resampling.

Bit-Perfect to Your Listening Room

Sit by your CD shelf, browse a disc, and send the music — untouched, uncompressed, exactly as mastered — to any Chromecast-enabled device on your network. No re-encoding, no Bluetooth compression, no app on the receiver. Just sixteen-bit, forty-four-point-one PCM, streaming straight off the disc to your hi-fi.

The CD spins. The phone is the remote. The music plays where it should.

Archive Your Collection. Lossless.

Some discs are too precious to leave on the shelf — the out-of-print imports, the scratched favourites, the ones you'd rather not spin on a dying laser. Redbook reads each sector straight from the disc and encodes it to FLAC on-device, with zero recompression and zero quality loss. No cloud, no upload, no subscription. The bits that went onto the CD in 1987 are the same bits that end up in your library.

Tap the disc icon. Choose a compression level. Walk away. Come back to a tagged album.

SEMINER USB-C OTG SPLITTER WITH 100W PD PASS-THROUGH
If your phone doesn't supply enough bus power for a CD drive, this adapter fixes it. The splitter connects the drive as an OTG device while feeding external power through a second USB-C port at up to 100W. One cable in, drive and charger out — the phone stays the data host, the wall does the work.
