1 vs AudioPhi

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.
