1 vs vPlayer HiFi

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.

vPlayer HiFi is a dedicated audio player for those who care about sound quality above all else. ▸ Bit‑perfect — Custom AudioUnit pipeline with hardware sample‑rate. vPlayer matches your source rate so the system never touches your signal. ▸ Native DSD Playback — DSF and DFF up to DSD512, decoded through a custom engine with 3 selectable FIR decimation filters (Steep / Gentle / Wide Bandwidth). Choose 176.4kHz or 352.8kHz output. No transcoding, no compromise. ▸ SACD-R ISO Decoder — Native Scarlet Book TOC parser. DSD64 playback with selectable decimation (176.4 kHz or 352.8 kHz). ▸ Memory Playback — Preload entire tracks into a dedicated 600 MB memory buffer — enough to hold a full CD‑length album or a high‑rate DSD track. Eliminates jitter from live file I/O. ▸ Polyphase SRC + FIR Upsampling — 6 SRC algorithms from Linear to Sinc‑512 tap with Kaiser‑windowed polyphase resampling. Independent FIR upsampling at 2× / 4× / 8× with selectable tap count (31 / 63 / 127) and homomorphic Minimum‑Phase conversion. SRC and FIR are mutually exclusive — one clean path, no double‑processing. ▸ Formats — MP3 · AIFF · M4A (Lite). Upgrade to Pro for studio‑grade WAV / FLAC / DSD (DSF, DFF) native playback. ▸ 10‑Band Graphic EQ — ±12 dB manual adjustment with per‑band reference guide. Instant response, zero latency. Toggle on/off directly from the signal chain bar. ▸ 638 AutoEq Headphone Presets — Directly load fixed‑band EQ corrections from the oratory1990 measurement database. Pick your brand, pick your model, done. Preamp is auto‑computed to prevent clipping. ▸ Parametric EQ (PEQ) — Full 10-band parametric equalizer: frequency, Q, and gain per band, with peaking, low-shelf, and high-shelf filters.

Tap any chip to open its config panel — switch DSD filters, choose SRC algorithms, set FIR parameters, adjust EQ. Real‑time route detection shows your output device. ▸ Shazam Recognition — Identify any music playing around you with one tap. Built on Apple ShazamKit. ▸ Music Painting — Generative art engine. Every track paints a unique visual — Constellation or Impression style. Save and browse your gallery. ▸ Drag album folders via Finder or iTunes to the App's sharing folder. Pull down to refresh.
