XMOS USB HiFi sound card solution¶
More and more consumers are becoming dissatisfied with the audio output quality of old computers or mobile devices and are looking for external devices to achieve a higher quality audio experience. With the popularization of high-resolution audio formats such as PCM up to 32-bit/384kHz and DSD, there is a growing need for audio accessories equipped with high-performance DACs and corresponding processing capabilities to support the decoding and playback of these formats. In professional audio fields such as music editing, music production, and professional recording, high-fidelity audio output is also essential. People also want to enjoy high-end audio quality while running or traveling. The Phaten XMOS USB HiFi sound card was developed to meet these needs.
The Phaten XMOS USB HiFi sound card solution is designed to improve the audio output quality of computers or mobile devices. It connects to a computer or other digital audio source via a USB interface, providing higher audio resolution and sound quality performance than built-in audio processors. Below are the main features and working principles of the Phaten XMOS USB HiFi sound card solution:

Working Principles:
¶
Digital Audio Transmission: The USB interface serves as a data transmission channel, receiving digital audio signals from the computer or other digital audio sources.
Audio Processing: The received digital audio signals are decoded and processed, including decoding PCM or DSD formats, performing necessary sampling rate conversions, and digital signal processing.
Analog Output: The processed audio signals are converted to analog signals through the built-in DAC and amplified by the built-in amplifier to levels sufficient to drive headphones or speakers.
Output Interfaces: The final audio output is transmitted through the various interfaces on the device to connect to headphones, speakers, or other audio equipment.
