Android Lossless Digital Music Player

The Darwin architecture is HiBy’s in-house developed all new hi-res digital signal processing architecture. In a breakthrough evolution of traditional R2R architecture, the system includes resistor ladder linearity compensation, and for the first time includes advanced functions such as linear FIR filter, nonlinear harmonics control, switchable oversampling / NOS, and DSD bypass on portable equipment. The end-to- end flexible architecture is fully configurable, creating endless possibilities for future upgrades and endless evolution.

The Darwin architecture provides for up to 16x oversampling (and also NOS), with several filter types selectable to preserve linear phase and reproduce the original sound; also customizable to adapt to different earphone characteristics, ensuring adaptability to different earphones of different designs and driver configurations.

Complete R2R-based amplification stage

Full of musicality, vibrant and natural, the R2R-based amplification stage brings music alive and performers onstage in an immersive experience.

NOS mode bypasses oversampling and antialiasing, responding instantaneously to transients and stairsteps, converting to analog in the most raw and direct manner possible; Oversampling mode removes aliasing artifacts, enables all functions of the Darwin architecture, realizes personalized adjustments of sound signature, adapting to different earphones;

DSD bypass function

With separate LPFs for PCM and DSD, native DSD decoding on an R2R system is no longer an oxymoron. The DSD specific LPF effectively reduces HF noise caused by the delta-sigma modulation process, optimizing DSD audio reproduction.

Highly accurate audio crystal oscillators

Press button to toggle charging in USB DAC mode--uncharging mode reduces battery consumption on smartphone and isolates device from external power supply noise.

Earphone-specific tuning

We have already collaborated with 10 professional HiFi brands in and out of China, getting each brand’s sound tuning professional to tune the Darwin architecture’s various hardware parameters to their earphones’ characteristics to produce tailor-made tunings for each brand, all available at a touch of the screen; more to come…

It’s a wireless world

Supporting both Bluetooth audio reception (to wired earphones or USB output) and Bluetooth audio transmission (to Bluetooth earphones) at the Bluetooth 5 standard level, and supporting a plethora of Bluetooth codecs including UAT, LDAC, aptX, aptX HD, AAC, SBC etc. Highly stable 2.4GHz and 5GHz WiFi for reliable, ever-present online music access. Supporting DLNA / AirPlay / WiFi audio transfer.

HiBy OS the everlasting god of audio!

The HiBy OS is HiBy’s in-house developed system architecture for HiFi audio, optimized from the ground up for audio processing. Now adapted to the Android 9 OS, it opens the system up for free installation of any Android app, and also supports advanced audio functions such as USB audio input and output, wireless audio input and output and systemwide audio effects.

Systemwide Direct Transport Architecture now including USB

The Direct Transport Architecture has always been known for defeating the originally mandatory sample rate conversion of android for the onboard headphone output. Now, DTA can also bypass sample rate conversion for third party apps even when using USB audio, achieving bitperfect output from almost any app, to anywhere.
