XMOS/DSP CONCEPTS JOINT WEBINAR
In this short webinar, delivered in collaboration with DSP Concepts, we delve into the details behind the partnership, and explore the ways in which the combination of XMOS’ highly-deterministic, low latency xcore.ai platform and DSP Concepts’ Audio Weaver software is revolutionising the audio and voice product development process.

DSP for audio Applications
The xcore.ai multichannel audio board includes support for full and high-speed USB operation, USB Audio Class 2.0 & 1.0, MIDI, HID & DFU classes.
The board integrates four stereo audio DACs and two quad channel audio ADCs supporting eight simultaneous bi-directional audio streams. It also includes electrical and optical interfaces for S/PDIF and MIDI In and Out ports.
DSP LIBRARIES
- lib_audio_dsp
- lib_xcore_math – a comprehensive library of maths functions
- lib_src – sample rate conversion library
DSP for Voice Applications
- 2-microphone front-end
- Audio pipeline including echo cancelation, interference cancelling and noise suppression
- I2S to USB interface supporting asynchronous sampling rates between 44.1 kHz – 192 kHz
- Bidirectional signal path
