Xenomai-enabled BeagleBone audio cape offers 1ms latency
A Kickstarter funded “Bela” cape for the BeagleBone Black uses Xenomai Linux real-time extensions to provide analog and digital audio I/O with 1ms latency.
There are a variety of audio capes for the audio-deprived BeagleBone Black, such as Element14’s $56 BeagleBone Audio Cape. Yet, the $76 Bela is unique. Developed by the Augmented Instruments Lab of the Centre for Digital Music at Queen Mary University of London, the cape adds ultra low latency analog and digital audio, as well as digital I/O for sensors. The Bela system is designed primarily for digital musical instruments and interactive audio systems, including battery-powered and gesture-controlled devices.
