+# **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.<br>
