Music Box Setup vs Nyquist Player

The Music Box Setup app is required to connect your Music Box to your existing home Wi-Fi network. Follow the on-screen instructions to connect your device. Once connected you will be able to play back Spotify content directly from the Spotify app using Spotify Connect (see https://www.spotify.com/uk/connect for full details). Full instructions are available in the associated user guide that comes with the product. The Music Box is capable of playing back audio via DLNA and DMR using any of your favourite NAS streaming apps. You can also playback Internet Radio via the UNDOK app from Frontier Silicon, also available for download on the app store (search for UNDOK).

Nyquist is a native, file-first music player for audiophiles who keep large local libraries on SSDs, external drives, and NAS shares. It is not a streaming app — it is a fast, precise playback tool built for people who care about sample rates, bit depth, and an honest signal path. WHY NYQUIST • Bit-perfect intent — On macOS, Nyquist matches your DAC's hardware sample rate to each file (44.1 → 88.2/176.4, 48 → 96/192) and waits for the clock to re-lock so CoreAudio performs no resampling. No cross-family conversions are ever forced on your music. • True gapless playback — Sample-accurate transitions between tracks of the same format, so albums by Pink Floyd, Tool, Daft Punk, live sets, and classical recordings flow without a single gap. • Network play — Discover UPnP/DLNA receivers on your network (Denon, HEOS, and friends) and stream the original file straight to them, with gapless hand-off on receivers that support it. Network devices sit right next to your DACs in the output picker. • Track analysis — A built-in lab for every file: a whole-track waveform with peak, RMS, and dynamic-range readouts; EBU R128 / BS.1770 integrated loudness with ReplayGain; a long-term spectrum that exposes upsampled "hi-res" and lossy-sourced "lossless" files; a full spectrogram; plus live spectrum, level meters, and a stereo goniometer — each with a plain-language verdict. • On-device search — A private, persistent index of your saved locations, with filters by file type and metadata field (title, artist, album, genre, composer, label, year, format). Nothing leaves your device. • Built for huge libraries — Folder-first browsing that behaves like a high-performance file browser, not a slow database. Lazy-loaded discovery means no full-library scan before you can press play, even across 50,000+ tracks. A topology view classifies your folders into artists, albums, EPs, singles, live sets, compilations, box sets, and discs. • NAS-aware — Add SMB shares directly or through the Files app. Remote tracks start instantly while a background copy makes seeks immediate, and the next track is prefetched for seamless rotation. • Playlists — Organize your music into groups and playlists saved as portable .m3u8 files in a folder you choose. Point every device at the same folder — including a NAS share added through the Files app — and your playlists stay in sync across Mac, iPhone, and iPad. Build them from tracks, whole folders, or the current queue, then reorder and edit them anywhere. • Background playback — On iPhone and iPad, playback keeps going when you lock the screen or switch apps, with working lock-screen and Control Center transport — including while streaming to a network receiver. • Flexible volume — On iPhone and iPad the slider follows your device's system volume; on macOS, choose software gain, your DAC's own hardware volume (bit-perfect at any level), or a fixed 100% for maximum purity. An optional limiter caps the level across every output — even against the hardware volume buttons — to prevent accidental loud jumps. • Exclusive (hog) mode — Optionally take exclusive ownership of your DAC during playback on macOS. • Flexible output routing — On macOS, choose the exact CoreAudio output device (USB DAC, built-in, and more); your choice is remembered across launches. On iPhone and iPad, send audio to AirPlay, Bluetooth, or wired outputs with the system route picker. • Deep technical transparency — Inspect format, sample rate, bit depth (with FLAC/ALAC recovery), channel count, codec, and a live signal-path view showing source rate, output rate, and bit-perfect / resampling / exclusive status. • Memory-friendly — Tracks are streamed from disk frame-by-frame, never decoded whole into RAM, so even 24/192 material stays light on resources. SUPPORTED FORMATS FLAC, ALAC, MP3, AIFF, WAV, and AAC today. The engine is format-agnostic, with DSD and SACD ISO planned.
