The Darwin Architecture

The Darwin Architecture

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.

256-tap adjustable FIR filter

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

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.

Switchable oversampling / NOS

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;

Switchable oversampling / NOS
DSD bypass function

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

The two crystal oscillators for the 44.1xkHz and 48xkHz families are clocked at 45.158MHz and 49.152MHz respectively with subatomic precision down to -140dBc/Hz @1kHz, DSD256 enabling 768kHz and DSD256 decoding at down to 0.003% / -115dB THD.

Earphone-specific tuning

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…

MQA 16x unfolding

The strong processing power of the SoC makes an unprecedented 16x unfolding of MQA data possible, reproducing the original master tape from ever smaller source files!

MQA is an award-winning technology that captures and reproduces the sound of the original studio master in a file that’s small enough to stream and download. HiBy is collaborating with MQA to deliver the true original sound quality to listeners.

Music Player Powered by Mature and high-performance SoC

Mature and high-performance SoC

Utilizing the highly mature and high performing Snapdragon 660, coupled with high speed LPDDR4 RAM and eMMC storage, enabling high demand multithreaded computations (audio or otherwise) to be performed in record time.

14nm LPP process, 8-core Kryo 260 architecture, 2.2GHz, Adreno 512 GPU 4GB LPDDR4 RAM+64GB storage+micro SD slot

Grand amplification scheme

To top it all off, a discrete current-mode amplification scheme is implemented via 1x OPA1642 and 2x OPA1612, supplying abundant current for the output stage to realize stellar dynamic and transient response. This is then coupled to 4 flagship-class OPA1622 opamps for 8 independent channels of headphone amplifications ganged 2x2 parallel; each channel is a combination of voltage and current amplification stages. This is all controlled by a professional NJW1195A digital volume controller for optimal control and ideal circuit dynamics at all times.

HiBy OS the everlasting god of audio!

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.
