Solution: USB HiFi Sound Card

The pursuit of the most authentic playback quality is a continually evolving direction in the HiFi audio field. When converting digital audio to analog sound, higher and larger data transfers are required to more effectively restore the real analog sound. In Hi-Res high-end playback devices, it is necessary to support higher sampling rates such as 384KHz/768KHz to carry a fuller spectrum information, a broader dynamic range, higher Signal-to-Noise Ratio (SNR), and lower Total Harmonic Distortion (THD).

As many terminal devices like mobile phones and PCs do not have built-in Hi-Res sound cards, using USB Audio to extend the sound card is the best choice for pursuing high-quality HiFi audio playback. The HiFi USB Audio solution implements the USB UAC2.0 protocol for asynchronous transmission of high-definition bitrate audio, achieving up to 768KHz PCM and DSD 512 audio decoding, delivering timely, bit-perfect audio parsing, and meeting the demands of HiFi audio consumers for high fidelity lossless playback devices.
