Codename "Inner Light". New DAC profiles: iFi GO link (Axel Arenas and SnOpeth); FiiO KA11 (42l6); FiiO QX13, Snowsky Tiny A and Luxsin X8 (Graham Lyth); Headphone Zone x ddHiFi Hi-Res DAC; JCALLY JM98MAX. Thank you for sharing your profiles! A new Now Playing: choose a rounded Card over a soft blur or immersive Full Screen on iPhone and in narrow iPad windows. Tap the artwork button to switch; press and hold for artwork and framing options. Refreshed typography scales with your text size. Your bridge's own player: when 1-bit recognises your bridge's own player, cast to it and see the source and player details in Signal Path. More network players: play to MPD and OpenHome players, and add an MPD player's own library under Sources (experimental). When your bridge identifies its box's MPD player, 1-bit groups that player's entries into one row in the player picker. Playlists across devices: keep favorites and playlists in step through a shared bridge with their backups on. Import playlist files from your bridge, or export a playlist as M3U8. Full changelog: https://1-bit.app/changelog/

NEW IN 2.1 • Big files start sooner: large FLAC, WAV and AIFF files can start playing while they download, instead of waiting for the whole file. Turn it on in Settings → Audio. • More DSD choices: set DSD conversion to Always, or play DSD as PCM on just the one DAC that needs it. The conversion level now goes from +6 down to 0 dB, one step at a time, for recordings that would clip at +6. • Your library, your order: choose how each list is sorted and laid out in Settings → Library → Browsing. Artist pages now show the newest albums first, and sorting albums by year adds a year index along the edge. • A tidier Artists list: artists who only appear on compilations no longer crowd the Artists list; you can bring them back in Settings → Library → Compilations. • A home for your DACs: DACs have their own page in Settings, one row per DAC, with Profile my DAC right there. Plug in a DAC the app doesn't know yet and the Audio page invites you to profile it. • iFi DACs, thanks to Axel: 1-bit now recognises iFi USB DACs, thanks to the profile Axel Arenas sent in with Profile my DAC. • More room to scroll: the tab bar shrinks while you scroll, with the mini player beside it, and comes back when you scroll up.

Codename "Unfinished Symphony". A round of fixes on top of 2.0, the largest release since 1-bit launched. FIXED IN 2.0.1 • Theme follows iOS again. With Theme set to System, light and dark switch with the system, and a theme you pick applies right away rather than after a relaunch. • Gapless over a remote bridge. The next track is fetched early enough to join gaplessly, timed by the connection's measured speed. • A change to DSD conversion or its level, the stereo effect or ReplayGain now reaches the next track even when it is already lined up for gapless. • When another app's audio interrupts playback, the track resumes with sound, and the timer stays where the music is. • Artist pages fetch a portrait that is missing, and the header of a guest appearance opens the album. • Signal Path claims a verified bit-exact path only when nothing alters the bits, and Now Playing says when a bridge-optimized copy is playing over Bluetooth or AirPlay. • Albums show a favorite heart on their page and in lists, and a track that comes back over a bridge keeps its playlist slots, heart and download. • Tracks from an SACD .iso no longer refuse to play over storage they do not need; Siri no longer stops on an SACD container in a playlist, and CarPlay no longer lists one as a blank row. NEW IN 2.0 • 1-bit Cloud (beta): a private bridge that we run, so you don't have to leave a computer switched on at home. Sign in with Apple, add music from any computer through the web uploader, and it appears in Sources like any other bridge. 20 GB is included free. • Lyrics: synced lyrics that follow the music line by line, read from the file's own tags, from a sidecar beside it, from your bridge, or from an online source you switch on yourself. Tap the artwork on Now Playing and it becomes the lyric sheet. • DSD on any output: DSD used to refuse anything but a wired DAC. It now plays on AirPods, AirPlay, CarPlay and the speaker, converted to PCM on the phone and labeled as converted wherever it is shown. A capable wired DAC still gets the untouched bit-exact path. • SACD rips and compressed DSD: an SACD .iso now opens into ordinary per-track rows that play and download like anything else, and DST-compressed DSDIFF files that were refused outright now decode as they play, gaplessly. • DSD256, and a wizard for your DAC: DSD256 over DoP is confirmed working, so the ceiling that used to sit at DSD128 is gone on hardware that supports it. Diagnostics adds Profile my DAC, a guided set of measurements you can send in so your hardware gets supported properly. • Built for iOS 27: on iOS 27, the Lock Screen, Control Center and CarPlay controls run on Apple's new Now Playing session, including shuffle, repeat and the Favorite heart. Tracks stored on this device that carry no loudness tag get an on-device loudness estimate, so ReplayGain can level them too. Everything keeps working on iOS 26.1 and later. ALSO IN 2.0 • Your bridge can convert DSD ahead of time so it streams a fraction of the size. • The floating player arrives on iPad. • A flat Tracks list. • Better tags and artwork from files on your device. • A redesigned Now Playing. • Multiple fixes. The full changelog is at 1-bit.app/changelog. If anything seems off after updating, write to support@1-bit.app. A big thank you to everyone who has sent feedback and reports. Much of this release traces back to those messages.

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.

• 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.

• 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.

• New source: UPnP/DLNA media servers on your network (NAS, MiniDLNA, Plex, Chord 2Go) — found automatically, played bit-exact. • 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.

• 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) • Redesigned album, artist, and playlist pages; smoother, freeze-free browsing on large libraries • Automatic recovery from iOS audio interruptions, plus many stability and reliability fixes

• CarPlay: browse Recently Added, Artists, Albums, and Playlists; tap-to-play with Now Playing and Up Next. • Offline downloads: pin albums, playlists, or individual tracks for bit-exact playback without a network. • Built-in log viewer for troubleshooting your own sessions — logs stay on device. • Smoother DSD256/512 playback under sustained load with a thermal-aware buffer ladder. • Headphone Safety and DAC volume guidance cards on first connect of a USB DAC. • Faster cold-start probing for SMB and bridge sources — first listing appears sooner on launch. • Now requires iOS 26.1 or later.

• DSDIFF (.dff) bit-exact playback joins DSF / FLAC / ALAC. • Folder long-press actions — Play, Add to Queue, Play Next, Create Playlist directly from any folder. • Classical metadata first-class — composer, conductor, work, BPM, original year in rows and album headers. • Bridge upscale on Now Playing — pick a variant, switch mid-track, event-driven reconciliation. • First-track crackle gone on Hugo 2 and other Chord DACs via cold-start settle + prefill gates. • Performance + battery wins — first-scan resumes in the background overnight, smart cellular preload, thermal-aware IO buffer, snappier cold-start endpoint probing.

• Tap-to-pair bridges on your network — no QR code needed on the LAN; just approve on the bridge's admin page • Optional bridge-side upscaling — generate higher-rate PCM variants for older recordings on demand, with the original always preserved bit-exact • Smoother resume after screen-off and lock-screen suspends, especially on USB DACs • Reliability improvements for DSD playback, gapless transitions, and bridge connections • Assorted fixes

NEW SOURCES • 1-bit bridge: pair a free open-source companion server running on your Mac, Linux, or Raspberry Pi for HTTPS access to your music library. TLS-fingerprint pinning captured at pairing. Pair by QR scan, Bonjour discovery, or bridge:// deep link. • Multiple endpoints per bridge with automatic failover — keep one URL for your LAN and another for remote access (e.g. over Tailscale), and 1-bit picks the working one on each request. NEW AUDIO • Optional Bauer crossfeed for headphones and Bluetooth — a more speaker-like presentation. Automatically bypassed on USB DACs and DSD so the bit-exact path is preserved. • DSF playback now uses a lock-free ring buffer for the render path, with a producer task pre-filling ahead. The legacy render path is still available as an opt-out under Settings → Advanced. PLAYBACK POLISH • Eliminated the mid-track click when toggling shuffle / repeat. Next-track preload now arms in the last few seconds of the current track instead of immediately on track start. • "Previous" track button rewinds to the start of the current track after 5 seconds instead of 3 — matches Spotify and Apple Music. • Larger touch targets on transport buttons; respect Dynamic Type up to AX5. • Optimistic play/pause feedback so taps feel instant on slow networks. • Tap to rescan when a moved or renamed track surfaces a missing-file error — no need to dig into Sources. • Recovery across lock-screen suspends, USB-DAC unplug/replug, Bluetooth handoff, and iOS 26 audio-engine resets that previously left the player silently stopped. • Pre-cache window protected by a background task so locking the screen during a DSF cache doesn't suspend the download. • Volume and route preparation refresh after route changes. LIBRARY • Bridge sources surface a "Bridge enriching" footer while the server is still tagging your library. • Bridge-supplied artist images now display correctly. • Faster search and album / artist list rendering on large libraries (50k+ tracks). • "Clear caches" now properly resets artwork flags so the next launch refetches. PRIVACY & TRANSPARENCY • Bundled Privacy Policy view, reachable from About. • Settings clarification: "Fetch artist images" is SMB-only — bridge sources fetch artist images from your bridge. UI & ACCESSIBILITY • Refreshed app icon. • Quality badge ("FLAC 44.1/16", "DSD128", etc.) bumped in light-mode contrast for WCAG AA. • Folders tab uses a unified NavigationStack so breadcrumb taps land where you expect on iPhone compact widths. • Per-endpoint visibility for bridge shares with multiple URLs. • VoiceOver improvements on info cards. Plus many SwiftData and scanner reliability fixes, including saved-state probes (SMB and bridge) that now happen before any data is persisted — a typo no longer half-adds a share. Thanks for listening with 1-bit.
