Darwin/Darwin MPA Question

Darwin

What is Darwin?

Darwin architecture is a new high-definition audio processing architecture independently developed by HiBy. It is derived from traditional R2R technology and integrates R2R resistor network linear technology. It pioneered the application of adjustable pure FIR filters, harmonic controllers, NOS/OS switching, DSD pass-through and other functions on portable playback devices. At the same time, its flexible architecture design is independent and controllable throughout the entire process, which also creates infinite possibilities for later upgrades and iterations, allowing the equipment using it to have the imagination space for continuous evolution.

What is HDR in Darwin?

HDR, also known as high dynamic range technology, is a specific algorithm for high dynamics in the HiBy Darwin architecture. You can experience a higher dynamic function when using the Darwin architecture.

What is Darwin's non-oversampling (NOS)?

Non OverSampling is a method for digital-to-analog conversion in which an audio signal is converted directly from its digital form to an analog signal without going through an oversampling process. To fully understand NOS, you must first master the basic concepts of digital-to-analog conversion and oversampling.
In digital-to-analog conversion (DAC), a digital audio signal composed of discrete samples is converted into a continuous analog signal that can be amplified and played through a speaker or headphone. This process is essential for converting digital audio data into sounds that can be heard and appreciated.
On the other hand, oversampling involves increasing the sampling rate of the audio signal beyond the original sampling rate. The technique is designed to reduce distortion and noise by averaging multiple samples, which theoretically improves the quality of the conversion. Oversampling is often used in modern DACs for improved performance and accuracy.
NOS DAC skipped this extra step. These DACs do not perform oversampling, but convert at the original sample rate of the audio signal. This approach can lead to different audio experiences, often characterized by its unique sound quality.

What is the atmosphere enhancement of the Darwin controller?

The atmosphere enhancement mainly enhances the low-frequency part of the sound.

What is Darwin's harmonic controller mainly used to adjust?

The main adjustment of the harmonic controller is the second harmonic, because generally speaking, the human ear prefers even harmonics because compared with even harmonics, odd harmonics are more harsh and discordant in the hearing.

What is Darwin's joint tuning?

Joint tuning is a series of tuning configurations jointly launched by HiBy and the headphone brand. It is the recommended configuration for their headphones on the corresponding players.
