Xenomai-enabled BeagleBone audio cape offers 1ms latency

Filed under
Linux

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.

The Bela system is designed primarily for digital musical instruments and interactive audio systems, including battery-powered and gesture-controlled devices.
