Background
Individuals/teams pursue high-definition recording to store and transfer genuine, wonderful sounds of vocals/instruments. More authentic sounds often require higher sampling rates to hold more sound spectrum information. Additionally, to meet the needs of singing performances, it is often necessary to blend more instrument sounds, individual singing, and background music.
Since existing end devices like computers and mobile phones cannot achieve higher quality recordings or simultaneously connect pianos/guitars, multiple high-definition microphones, and monitoring headphones, making them unable to meet music enthusiasts' requirements for singing performances. Using USB Audio devices is the best choice for professional recording sound cards through USB expansion. USB Audio solutions can implement USB UAC2.0 protocol asynchronous transmission, ensuring multi-channel, high-bit-rate audio transmission bandwidth. It also supports MIDI interfaces, multiple analog microphones, and monitoring headphone outputs, using the mixing algorithm (Mixer) to blend vocals and music.
Scheme Overview
The XMOS USB Audio solution is a cost-effective option among many USB professional recording sound card solutions. Excellently combining XMOS's proprietary XCORE architecture, high inversion, and flexible I/O, high precision clock synchronizationcurities, and high fidelity digital audio transmission. The standard UAC2.0 (USB Audio Class 2.0) protocol and asynchronous transmission mode ensure USB high bandwidth transmission of high-definition audio data while being highly compatible with major operating systems such as Windows, Android, Linux, etc. It also integrates a comprehensive HID protocol, enabling flexible HID control instructions reporting.
In XMOS's USB professional recording sound card solutions, the asynchronous clock mode within USB protocol is used, where the clock source synchronized between the PC (Host) and the playback device (Device) is the on-board low clock jitter active clo... (truncated due to character limit)
