Reference design for USB Audio 2.0
XMOS Semiconductors has announced a reference design for USB Audio 2.0, which enables standard computer-based systems to deliver bit-perfect prosumer quality sound.
Implemented entirely in software, using the XMOS XS1-L1 event-driven processor, the design supports high-speed USB Audio 2.0 connectivity and up to six input and six output audio channels at 24-bit resolution and a sample rate of 192kHz.
Higher audio channel counts are also supported using the XMOS L2 and G4 devices.
The reference design's asynchronous clocking mode achieves sub-3ms roundtrip latency, making it suitable for live music playback.
The credit-card-sized reference design board is said to suit the development of speakers, home theatre systems, sound cards, musical instruments and professional audio equipment.
The reference design's software-defined workflow also enables users to readily adapt and customise the solution to handle specific interfacing requirements, DSP algorithms for audio enhancements and custom 'front-of-box' peripherals.
To reduce development time, XMOS's readymade library of software components already includes I2S, S/PDIF and many other interfaces.
The design works with the Mac OS-X 10.6 (Snow Leopard) Audio 2.0 native class driver, and XMOS has teamed with Thesycon to provide Audio 2.0 Class driver support for Windows.
