Build entire DSP systems using software alone
Build with XMOS
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
- For more information see our xcore-voice platform
