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.
