1 vs Vivace

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, a folder on your device, or 1-bit Cloud, a private library we host for you. No analytics, no ads, and no account unless you choose the cloud. 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. • 1-bit Cloud: the same bridge, run by us. Sign in with Apple, upload from any computer, and it appears in Sources. 20 GB free. Strictly private, downloadable bit-exact, deletable in one step. • Any folder on your device or an external drive, picked in Files, nothing copied. Download for 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 DSD256, with a USB DAC that reports DoP lock (Chord, iFi, Topping, Mytek and others). • DSD on any output: AirPods, AirPlay, CarPlay and the speaker play DSD converted to PCM on the phone and labeled as such. A wired DAC still gets the untouched path. • SACD .iso rips open into per-track rows; DST-compressed DSDIFF decodes as it plays. • Gapless when adjacent tracks match. Per-DAC tuning, anti-click rate switching and thermal-aware buffering keep DSD256 smooth. • Spatial audio (beta): a binaural renderer with head tracking on supported AirPods. PCM only. • Large FLAC, WAV and AIFF files can start while they download (optional). LYRICS • Synced lyrics that follow the music line by line, from the file's tags, a sidecar, your bridge, or an online source you switch on yourself. Tap the artwork on Now Playing. SEE WHAT YOU HEAR • Signal Path shows what actually reached your DAC, with an optional live spectrum and true-peak analyzer. • Whole-track analysis answers "is this really hi-res?"; a bridge adds dynamic range, key, tempo and a FLAC checksum that flags an altered file. • Profile my DAC: guided measurements you can send in so your hardware gets supported properly. VOICE, SIRI & CARPLAY • "Hey Siri, play [album, artist, playlist, or genre] on 1-bit". Shortcuts and Spotlight too. • CarPlay: Recently Added and Played, Artists, Albums, Playlists, Favorites and Downloads, A to Z indexed, with voice search and Shuffle. Its browser lists PCM; DSD started from the phone plays converted. HOME MIXES (WITH A BRIDGE) • Your bridge builds mixes from your listening: Heavy Rotation, Daily Mix, On Repeat, Favorites and more; they can cache overnight for offline play. OUTPUT • Play through a USB DAC, AirPods, AirPlay 2 or the speaker, or cast to a DLNA renderer such as a Chord 2Go. LIBRARY • Fast enough for 50,000+ tracks across every source; the first scan carries on overnight while charging. • Browse by artist, album, composer, genre, folder, playlist or a flat Tracks list, with an "Appears On" section. Search everything, filter by source. • Heart tracks and albums; Favorites can follow you across devices with a bridge. PLAYER • A redesigned Now Playing with a waveform scrubber; the floating player arrives on iPad. • Resume where you left off. Home Screen widget, Lock Screen and Control Center transport, sleep timer, optional crossfeed. BRIDGE EXTRAS • Upscaling and DSD-to-PCM renditions made on your own hardware, the original always one tap away. • Atlas notes and better cover art; backup of playlists, favorites and playback history to your own bridge. All off by default on a bridge you run. PRIVACY • No analytics, no tracking, no ads. Optional lookups are off by default; passwords and tokens live in the iOS Keychain. The only server of ours that holds anything is 1-bit Cloud, and only if you create a library. Requires iOS 26.1 or later.

AI SUGGESTIONS, YOUR CHOICE Add AI suggestions to an ordinary playlist for Driving, Gym, a mood or your own activity. Use the songs already there and optional examples to guide it. Search songs, artists and albums, listen in Preview, then select what to add. Remove saved songs and keep using normal playlist controls. Feedback does not replace your preview; refresh when you are ready. Recommendations use your library's metadata, sampled audio characteristics and feedback on this device. Audio and activity descriptions are not uploaded to an AI provider. AI functions require active Pro; existing playlist songs remain playable under their format entitlements. Activity preferences and Home layout stay on this device. The free iPhone/iPad player includes a browsing banner and occasional full-screen ads at eligible app openings. Full-screen ads are not presented during playback. Pro also works in the native Mac app with the same Apple Account. Monthly and annual subscriptions renew automatically until canceled. Lifetime is a one-time purchase. Current localized prices and eligible offers appear before purchase. Trials are available only when offered by the App Store for your account. Manage subscriptions in Apple Account settings; restore purchases in Vivace. Output depends on the file, sound settings and connected hardware. Gapless transitions require compatible formats and processing; normalization can introduce a short gap when songs need different adjustments. Bluetooth and AirPlay may convert audio.
