Description
A purpose-built audio engine for listeners with local libraries. The Engine delivers bit-accurate playback to UAC1 and UAC2 DACs (including USB headphones with integrated DACs), with a transport path built for fidelity and a library system that exceeds Android's reach.
Output through Android or over Bluetooth remains available — for those who would have convenience over fidelity.
ENGINE Three fidelity doctrines govern the Engine:
Wide — the Engine selects the best available format. All tracks adapt to fit.
Source Matching — native sample rates are preferred above all else. The Engine seeks fidelity before convenience.
Bit Perfect — integer PCM delivered to the wire without float conversion, without DSP, without headroom adjustment. Native DSD up to DSD2048 via dedicated transport, if your DAC and device are sufficiently sanctified. Mono and stereo sources only. Nothing is added. Nothing is taken.
Four pipeline domains carry the signal — Float32, Integer Passthrough, DoP, DSD Native — chosen by doctrine, not by guess.
Three fidelity tiers declare what the engine does to your signal — BIT PERFECT, LOSSLESS PROCESSING, DSP ACTIVE — with ATT suffixes when digital volume is engaged. The Engine does not lie.
SEALED WITNESS Bit-perfect is not merely declared; it is proven. The Sealed Witness computes CRC32 integrity checksums at two points in the pipeline — the decoder's output and the moment of USB submission — and compares them in real time. If they match, the signal has crossed the Engine untouched. If they diverge, the Engine states the cause. No other player verifies its own integrity chain at the wire.
DSP 31-band parametric and graphic equalizer with per-band bypass, logarithmic Q, direct gain entry, and automatic headroom attenuation to prevent clipping from EQ boost.
Partitioned overlap-save convolver for headphone impulse response correction. Load an AutoEQ profile from an integrated library of thousands. Crossfeed for speaker-like stereo imaging. Channel balance with per-channel precision.
Under Bit Perfect, all DSP is absent. The processors are not instantiated. The float domain is never entered.
LOUDNESS Loudness normalization two ways: ReplayGain, reading the mastering tag, and the Witnessed Measure, measuring each track by EBU R128 — never touching your files, yet preserving bit-perfect path.
RESAMPLER 8192-tap polyphase windowed-sinc resampler, 64 phases, Blackman-Harris window, four filter modes. It engages only when source and DAC sample rates differ — when they match, it does not exist.
DSD Native DSD for DACs that bear the mark — DSD64 through 2048. DoP framing for broad compatibility. DSD-in-WavPack and DST-compressed DSDIFF are decoded natively and routed through the same pipeline without decimation. When EQ or digital volume is active, DSD is decimated to PCM. The Engine confesses the cost; it never degrades silently.
DECODING Native FLAC via dedicated C bridge. DSF and DFF containers parsed by dedicated forges, including DST-compressed streams. FFmpeg for everything else — MP3, AAC, OGG, WAV, AIFF, ALAC, WavPack, APE, WMA, Opus.
LIBRARY A music-collection manager for the audiophile. Grant the Engine access to your music folders (including hub-mounted drives), and its custom-forged scanner surfaces complete collections where others fall silent or return them only in part: DSD, WavPack, APE, AIFF, FLAC, WAV, Opus, and more — alongside the companion files that make a true library whole: CUE, M3U, and folder-level album artwork. No format left behind. No folder unreached. No companion lost.
PLAYBACK Gapless playback via a proprietary mechanism — same-format transitions are zero-gap via a reservoir that decouples decode timing from USB delivery. Bit-Perfect Playlist probes your library against the connected DAC and admits only what reaches the wire unprocessed.
DIAGNOSTICS Real-time telemetry with one-tap export. Every parameter declared and auditable.

Wow The sound of this is exceptional!! There's simply no comparison with any other usb exclusive bit-perfect player (Tried them all) Clean No harshness More dynamics and open sounding i m really impressed Also there are no audio hiccups when listening to music on usb exclusive while opening/using other apps, which happens with every other player Wow

Amazing audiophile player. Love the deep insights into how the audio stream and audio engine/pathway is detailed down to every single lil aspect. Handles dac play through perfectly. All codecs handled. If I had 1 lil critique; itd be that the way the app is worded n its descriptions n tutorials are a bit flamboyant... they give the basic features n functions wild names to spice it up, which I can appreciate the idea, but in practice, it just makes things a lot more confusing than they need to be.
