We have discussed some hardware variants for the System für kontinuierliche Audio-Aufzeichnung (BOB Projekt, Phase 1) . The BeagleBone seems to be a suitable board for our requirements. Let’s have a look how we can use audio hardware on the BeagleBone.
USB Sound Card
The BeagleBone has an USB host adapter. So you can use a lot of “USB sound cards” on the board.
Special Audio Capes
What the shield for an Arduion is or the Hat for RasPi, is the cape for BeagleBone – a stackable adapter board in addition to the main board. I found some Capes for Audio. As far as I can see it has mostely the same functionality as the USB sound card but in an nicer and more compact form factor when it is stacked on the BeagleBone.
