Rust engine, direct to the DAC.
Samples reaching your DAC are numerically identical to the ones in the file. No resampling, remixing, or dithering on the way out — when bit-perfect is achievable, you get told.
Bit-perfect Hi-Res audio with on-device AI
Nothing between the file and your DAC
A Rust audio engine takes exclusive control of USB Audio Class 2 output straight to your DAC — no resampling, no system mixer, no silent format conversion.

Core Capabilities
Everything in the signal path
Exclusive USB output.
The OS internal mixer is bypassed entirely. The player opens the audio device directly and drives it at the file's own sample rate and bit depth.
Parametric EQ, up to 32 bands.
Seven filter types, ±12 dB per band — ±24 in expert mode — Q from 0.1 to 10. A simple ten-band graphic mode when you want it, free per-band control when you don't.
Sources are separate apps.
Plugins ship as their own signed APKs and only ever hand back a URL. Audio never crosses into their process.
Casts both directions.
Six protocol families, send and receive — TVs, smart speakers, network streamers, open receivers. The phone can be the player in the room or the renderer other apps cast to.
Library and formats.
Every format the engine decodes: FLAC, ALAC, WAV, AIFF, DSD, APE, WavPack, Opus, Vorbis, MP3, AAC. Indexed and searchable.
Getting Started
How It Works
01
Install from Google Play
Free to install, no account, nothing to sign up for. One APK, every ABI — Android 8.0 and up.
02
Connect your DAC, or cast
Plug in a USB DAC for exclusive output, or send audio to a renderer on your network — a TV, a streamer, another device.
03
Play
The engine sends your file's own bits, untouched — no resampling, no system mixer, no silent conversion.
The Engine
The engine takes the output, not a turn in the queue.
Most Android players hand audio to the system mixer, which resamples whatever it likes to whatever the device happens to be running. Bitperfect claims the USB device node directly — exclusive access, no mixer in the path — and drives it at the file's own rate.
One file, one path to the DAC
- Source file FLAC 24/192
- Bitperfect engine no resample
- UAC2 out exclusive
- Your DAC 24/192
Bit-perfect Output identical to source. Nothing resampled, nothing mixed, nothing scaled.

On-Device AI
The models live on the phone
An enhancer that reconstructs what lossy encoding discarded, and a mixer that maps your library. Both models execute on the device — nothing is uploaded. No audio, no fingerprints, no titles.
AI Enhancer
Lossy encoding throws away content between its cutoff and the format's own ceiling, and roughens what it keeps. During playback, the enhancer reconstructs a plausible estimate of that missing content — in-band, at the same sample rate, never bolting a new octave on top. It predicts phase as well as amplitude, which is the part that naive "fill the top" tricks skip, and why those sound metallic.
The engine runs a custom deep neural network optimized for direct on-device hardware acceleration. An optimized model is automatically compiled and target-matched for your device's specific hardware capability, downloading only what your phone requires. In Restore mode, it repairs damage below the cutoff — quantization noise and smeared transients — as well as reconstructing high-frequency detail.
Before offering it, the app measures that accelerator and enables only what runs in real time. If your phone can't, the enhancer stays hidden and playback is untouched. When it's on, the signal state re-reads as enhanced — the badge never claims a purity the DSP spent.

Real-time neural inference: ~45 ms latency per chunk (RTF 0.15), well within the 348 ms real-time buffer window.
Diagram of the operation — not a measurement.
AI Mix
Pick a few tags — mood, era, energy — and it builds a mix from your library. Not a stream, not other people's music. Tracks you already own, re-sequenced.
Mixes also arrive on Home on their own: a favourites mix, rediscoveries you haven't played in months, decade mixes. Any track can start a radio of its neighbours, and AI search finds music by description.
The mechanism, plainly: two on-device models read every track at five points — a similarity embedding and a 50-tag analyzer. Your library gets a map. The map never leaves the phone.

FAQ
Questions worth asking.
Straight answers about bit-perfect output, on-device AI, and what Pro actually costs.
What does "bit-perfect" actually mean here?
That the samples reaching your DAC are numerically identical to the ones in the file. Bitperfect opens the USB audio device directly and drives it at the file's own sample rate and bit depth, so nothing resamples, remixes, or dithers on the way out. When that is not achievable — a device that will not surrender exclusive access, say — the app says so rather than claiming otherwise.
Do I need an external DAC?
No. Bitperfect plays through your phone's own output too. But the default system path routes through the system mixer, which sets its own rate — so the bit-perfect state specifically describes USB Audio Class 2 output to an external DAC. The app labels whichever path you are actually on.
Is the AI processing optional?
Yes. Every AI feature ships off and stays off until you enable it — they are part of Pro. The enhancer alters the signal by design, so switching it on re-labels the signal state as enhanced rather than bit-perfect. That is deliberate: the badge never claims a purity the DSP just spent.
What does the app send over the internet?
Three things. Crash reports — on by default, and one switch turns them off. Artwork lookups — on by default, also switchable — which send artist and album names to public image sources and nothing more. And a one-time download of model files when you enable an AI feature. That is the whole list: no analytics, no ads, no account, no listening history. Audio never leaves the phone.
Which platforms and devices are supported?
API 26 through current, on every ABI. Everything except the AI Enhancer runs on any device that clears that bar. The Enhancer needs hardware NPU acceleration — flagship-class platforms from 2022 onward, premium mid-range from 2024 — and the app probes the accelerator before enabling the feature rather than assuming it will work.
See the compatibility checkCan I add streaming sources?
Through plugins, which are separate signed apps. A plugin resolves a stream URL and hands it back — it never receives decoded audio, and none of its code runs inside the player's process.
What does Pro cost?
$2 a month, $9 for six months, or $12 a year — which works out to $1 a month. You buy it in-app; Google Play handles the billing. It renews automatically until cancelled, and you can cancel anytime in Play's subscriptions screen. The player, the EQ, casting, and plugins never need Pro.
Do AI features work offline?
Yes. The models download once, when you first enable a feature. After that everything — enhancement, mixes, similar tracks, search — runs on the phone with no connection at all. There is no server side to be offline from.
