Tessera : Hi-Res Music Player

Tessera is a hi-res music player for people who care how their music actually sounds — and for anyone ready to start caring.

It plays your files the way they were mastered: no hidden resampling, no system mixing, no "enhancement." When your hardware allows it, audio reaches your DAC bit-perfect — the exact samples, untouched.

— NEW TO HI-RES? START HERE —

Most players quietly convert your music before it reaches your ears. Tessera doesn't. Add your files, press play, and see what's happening at every step — format, sample rate, and what your device receives. A good USB DAC makes it better; curiosity is enough to begin.

— BUILT FOR REAL HI-RES —

DSD playback: DSD64, DSD128 and DSD256 go native to a capable USB DAC over DoP, or convert to high-quality PCM if you prefer. DSD512 files play too, converted — iOS cannot carry DSD512 natively over USB

PCM all the way to 32-bit / 768 kHz, at the file's original rate and depth — FLAC, ALAC, WAV, AIFF, MP3, AAC, Ogg Vorbis, Opus, WavPack, APE and Musepack

Bit-perfect exclusive output, handing the clean signal straight to your DAC

Audio Details: source file, output device and the whole chain — resampled or untouched, you always know

Real-time spectrum reaching into the ultrasonic range, with a gold zone above 20 kHz

— YOUR LIBRARY, EVERYWHERE —

Play files you own, or stream from a NAS, WebDAV share or DLNA/UPnP media server — discovery finds it in seconds

Tracks play while they download and the next is fetched ahead, so server albums begin instantly and keep going with the screen locked

Apple Music, too: browse tracks, albums, artists, playlists and genres, and play them straight to your DAC

Browse by Folders, Tracks, Artists, Albums, Genres, Format, Mood, BPM and Playlists — with fast search across the whole collection

Pin the ones you keep coming back to — hold the artwork on Now Playing, or long-press any track, album or artist. They gather at the top of Playlists

A customizable sidebar — rename, reorder and hide sections

— SEND IT TO YOUR SYSTEM —

Hand what you're playing to a UPnP/DLNA streamer — an amplifier, a speaker in another room — and keep the controls on your phone

Music on a server goes to the streamer directly. Music on this iPhone is sent too, album art included, with the screen locked and the phone in your pocket

Nothing is re-encoded on the way — this iPhone only passes instructions along

Streamers that keep their own queue take the whole album at once and finish it alone, even with the phone locked or closed

Everything stays live: track, position, volume, and the lock screen, Control Centre, headset and car controls

— SEE WHAT YOU'RE HEARING —

Format badges tell you exactly what's playing: "DSF DSD256", "FLAC 24/192", a gold Hi-Res badge for true hi-res files, and Lossless / Hi-Res Lossless / Dolby Atmos for Apple Music — turn each on or off

Bit-Perfect is claimed only when it can be verified. When output can't be confirmed, Tessera says so rather than guessing

— SMART PLAYBACK —

True gapless playback for lossless and DSD — live albums and classical works flow the way they should

Fade on Pause and Resume, so stopping and starting doesn't jolt — it steps aside on its own in bit-perfect mode, where nothing may touch the signal

DJ Flow: reads the energy, brightness, tempo and dynamics of your tracks so similar songs play together in a considered sequence

Mood and BPM grouping — your library sorted by feel and tempo

Sleep timer, play-count history, and resume where you left off

— DESIGNED WITH CARE —

A Liquid Glass interface that stays out of the way of the music

Choose one accent color, or give each section its own

Light, dark and automatic themes — localized in 10 languages

— YOUR MUSIC, YOUR DEVICE —

No account, no ads, no tracking, no subscription

One purchase. Yours to keep.

You don't need golden ears or a wall of gear — just your music, a little curiosity, and maybe a good DAC. Tessera is for the recording, not the algorithm.
