## What is 1?

1-bit is a private, bit-exact music player for iPhone and iPad. Play your own files from a UPnP/DLNA media server, an SMB share, your own 1-bit-bridge server, or a folder on your device. No cloud, no login, no account.

SOURCES
• UPnP/DLNA media servers on your Wi-Fi: NAS, MiniDLNA, Plex, a Chord 2Go. Found automatically, streamed bit-exact, DSD included.
• SMB shares on your home network.
• 1-bit-bridge, a free, open-source (MIT) server you run on Mac, Linux, Pi, or Windows. Pinned HTTPS, tap-to-pair by Bonjour or QR.
• Any folder on your device or an external drive, picked in Files, nothing copied. Download for bit-exact offline play.
• No server yet? Add the read-only demo library in one tap.

AUDIO
• Bit-exact PCM (FLAC, WAV, AIFF, ALAC, MP3, M4A) up to the limits of your DAC.
• Bit-exact DSD over DoP for DSF and DSDIFF, up to DSD512, with a USB DAC that reports DoP lock (Chord, iFi, Topping, Mytek and others).
• Gapless when adjacent tracks match. Per-DAC tuning, anti-click rate switching, and thermal-aware buffering keep DSD256/512 smooth.
• Spatial audio (beta): a binaural renderer that opens stereo out around you, with head tracking on supported AirPods. PCM only; DSD untouched.

SEE WHAT YOU HEAR
• Signal Path shows what actually reached your DAC, with an optional live spectrum and true-peak analyzer that only reads the audio.
• Whole-track analysis answers "is this really hi-res?" by measuring where the music actually stops. A bridge adds dynamic range, key, tempo, and a FLAC checksum that flags an altered file.

VOICE, SIRI & CARPLAY
• "Hey Siri, play [album, artist, playlist, or genre] on 1-bit", at home, hands-free, or in the car. Shortcuts and Spotlight too.
• In CarPlay: Recently Added, Recently Played, Artists, Albums, Playlists, Favorites, and Downloads, A to Z indexed, with voice search and one-tap Shuffle.
• PCM only over CarPlay; DSD stays hidden to avoid head-unit incompatibility.

HOME MIXES (WITH A BRIDGE)
• Your bridge builds mixes from your listening: Heavy Rotation, Daily Mix, On Repeat, Favorites and more. Your history never leaves your server, and mixes can cache overnight for offline play.

OUTPUT
• Play here through a USB DAC, AirPods, AirPlay 2, or the speaker.
• Or cast to a DLNA renderer such as a Chord 2Go, streaming from the source and keeping your iPhone out of the path.

LIBRARY
• Fast enough for 50,000+ tracks across all your sources, with the first scan carrying on overnight while charging.
• Browse by artist, album, composer, genre, folder, or playlist, with cached artwork and an "Appears On" section for guest spots. Search everything and filter by source.
• Heart any track or album for a Favorites section that can follow you across devices when you run a bridge.
• Composer and Genre pages tuned for classical name forms and multi-genre tags, alongside conductor, work, original year, BPM and performer credits.

PLAYER
• Now Playing with a real waveform scrubber, drawn on device when your source has none, plus a signal-path readout.
• Resume where you left off; queue and position come back after closing.
• Home Screen widget, plus Lock Screen and Control Center transport.
• Offline, playback moves on to the next downloaded track instead of stopping.
• Sleep timer, plus optional crossfeed and spatial audio for PCM.

BRIDGE EXTRAS (ALL OFF BY DEFAULT)
• Upscaling: higher-rate PCM variants made on your own hardware, with the original always one tap away.
• Atlas: artist and album notes plus better cover art, fetched anonymously.
• Backup: playlists, favorites, and playback history to your own bridge, never shared.

PRIVACY
• No analytics, no tracking, no ads, no accounts. Optional lookups (Deezer artist images, Atlas metadata) are anonymous and off by default.
• Passwords and tokens live in the iOS Keychain. Traffic stays on your LAN unless you reach a remote bridge, and logs stay on the device unless you share them.

Requires iOS 26.1 or later.

## Version history (last 5 releases)

### 1.9 — 2026-08-25

NEW
• Spatial audio (beta): a binaural renderer that opens stereo out around you, with head tracking on supported AirPods. PCM only, DSD untouched.
• Live audio meters: a real-time spectrum and true-peak analyzer in Signal Path, fed by a tap that only ever reads. Off until you switch it on.
• Favorites: heart any track or album and find them all in one place. With your own bridge they back up across devices and feed a new Home mix.
• Composers and Genres: two new ways to browse, tuned for classical name forms and multi-genre tags. Both work in search, and Siri takes genre requests.
• Deeper analysis: bridge tracks show measured true peak, dynamic range, key and tempo, plus a FLAC checksum that flags a modified file.
• Demo library: no bridge of your own? Add the read-only demo library in one tap and try the whole thing.
• Waveforms drawn on your device when your source has none, DSD included.
• A thermal and battery dashboard in Diagnostics, and refreshed typefaces throughout.

IMPROVED
• Library sync reports honest progress and pulls far less artwork data when your bridge is up to date.
• Offline, playback moves on to the next downloaded track instead of stopping.
• Downloads report their real state, so a playlist can no longer claim to be fully offline when it is not.
• Renamed or moved files keep their identity instead of vanishing until a full rescan.
• Steadier CarPlay: a pause stays paused, and playback comes back after Siri interrupts it.
• Fixes across playlists, iPad layout, and bridge pairing.

Thank you for the feedback and reports. A lot of this release started there.

### 1.8 — 2026-07-31

• Play from anywhere on your device — point 1-bit at any music folder through the Files app, external drives included.
• A waveform scrubber on the Now Playing screen, so you can see the track and scrub right to the part you want.
• Guest and featured artists are now browseable, each with an "Appears On" section for their collaborations.
• With a bridge: your Home mixes got a fresh look, and can be cached overnight on Wi-Fi so they play offline.
• Stability and playback fixes across sources, CarPlay, and widgets.

### 1.7 — 2026-07-03

• Siri & voice — say "Hey Siri, play [album, artist, or playlist] on 1-bit," on your phone or hands-free in CarPlay, with voice search and shortcuts.
• Home mixes — with a paired bridge, a new Home tab serves mixes built from your listening: Heavy Rotation, Daily Mix, On Repeat, Artist Deep Cuts, and more.
• Atlas (optional, off by default) — artist and album "About" notes plus higher-quality cover art, fetched anonymously.
• Smarter library — "The"-aware A–Z sorting, performer credits, and a configurable starting page.
• Audio polish — anti-click rate switching for smoother PCM↔DSD transitions, plus Mytek Brooklyn DAC+ support.
• More reliable DLNA casting, plus stability, metadata, and performance fixes.

### 1.6 — 2026-06-15

• Cast straight from a media server or bridge to a DLNA renderer, keeping your iPhone out of the audio path.
• CarPlay: Recently Played and Downloads, an A–Z index, and more reliable pause/resume.
• Richer Home-Screen widget: more sizes, transport controls, and a signal-path indicator.
• Resume where you left off — your queue and position are restored even after the app is closed.
• Stability: DLNA/DSD/SMB robustness and a fix for an iOS 26.5 playback crash.

### 1.5 — 2026-06-03

• Cast to DLNA network renderers (e.g. Chord 2Go) — the renderer streams straight from your bridge, with your iPhone out of the audio path
• New Home-Screen Now Playing widget (track, quality, Play/Pause)
• Filter your library — albums and artists — by source
• Optional playlist and playback-history backup to your own bridge (off by default)
