Take interactive audio to the next level
Multichannel audio allows you to take audio interaction to the next level. Our add-ons for both Bela and Bela Mini allow you to send audio to multiple channels while retaining all of Bela’s famous connectivity, performance and interactive features, meaning that these add-ons are the ideal way to make multichannel sound installations, route audio to separate speakers, or individually control an array of transducers.
Both CTAG and the Bela Mini Multichannel Expander are sold as standalone accessories, or as full starter kits.
Bela multichannel audio: CTAG #
CTAG is a multichannel audio accessory that uses the Bela software and Beaglebone Black. It comes in two sizes: FACE (4 audio in, 8 audio out), and BEAST (8 audio in, 16 audio out).
Pair CTAG with a Bela cape to add all Bela’s interactive and connective features (8 analog in, 8 analog out, 16 digital I/O) for a powerhouse system for multichannel audio applications.
