1 vs Serento

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.

Serento is the premium control point for UPnP/DLNA streamers and network DACs, built for audiophiles who demand bit-perfect playback and a modern, responsive interface. No account. No login. Just your music, your streamer, and Serento. BIT-PERFECT PCM & DSD True bit-perfect playback - PCM up to 32-bit/768 kHz and native DSD up to DSD512 - with automatic detection of your renderer's capabilities. DoP and Native DSD pass-through, no conversion, no downsampling. Your DAC receives exactly what's on your drive. INTERNET RADIO THAT ACTUALLY WORKS Curated presets for high-quality audiophile stations, including jazz, classical, and hi-fi showcase channels. Add your own stations via URL or M3U import. Live ICY metadata. Automatic reconnect on drops. No more fighting with broken URLs or silent failures. YOUR LOCAL LIBRARY, BEAUTIFULLY Browse music from MinimServer, Plex or any UPnP/DLNA server on your network. Albums, Artists, Tracks, Genres, Folder view and a beautiful Classical Music Section. Lightning-fast contextual search. MAKE IT YOURS Bookmark any filtered view - Hi-Res Jazz, FLAC from 2023 - and jump back in one tap. Group albums into your own tags. Save albums and tracks to Listen Later, split into Up Next and Listened. Album version grouping collapses remasters and reissues under one cover, your chosen main version synced everywhere. YOUR TAGS COME FIRST Serento trusts the tags already in your files before fetching anything. Beyond title, artist, album and genre, it reads MusicBrainz identifiers to match the exact release, and classical Work and Movement tags so multi-movement works stay grouped and in order. Your library's truth wins. KNOW EVERY RECORD Artist bios, album reviews, release years, labels and per-track credits - performers, composers, lyricists - pulled from Serento's database and layered on top of your library, never overwriting your tags. Mistagged album? Identify it by hand, or let a sync pass fill the gaps and fetch high-resolution covers automatically. A REAL CLASSICAL SECTION Browse by composer, work, conductor, orchestra, soloist, period or musical form - not one flat artist list. Open any work to see every recording you own side by side, movements in order, credits split by role. It stays out of the way until your library actually has classical in it. SMART PLAYLISTS Auto-generated playlists built from your own listening history - weighted by how often and how recently you play, then balanced across genre, era and codec. A different way back into your library every time. DOWNLOAD & GO Tap Download on any album, track or playlist and play straight from local storage - the same bit-perfect pipeline, zero network. Resumable, survives an app kill, per-device, excluded from iCloud Backup. EVERYTHING IN SYNC Queue, current track and volume mirror across every Serento device driving the same renderer - start on iPhone, pick it up on Mac, adjust volume from iPad, no master or follower. Your playlists, My Mixes, favorites, Listen Later and play history sync the instant you change them, near-instant over the local network, with iCloud carrying the rest. ON IPHONE, IPAD AND MAC Serento is available on iPhone, iPad and Mac, offering the same amazing experience on all of them and real time sync across devices.
