Depends on what your objectives are… - Ease of connectivity? Buy just about any USB microphone. Wire it up to the USB pins on the GPIO header (for PocketBeagle) or use one of the existing sockets (BeagleBoard/BeagleBone). Let ALSA's USB audio device deal with the software stuff. - Audio fidelity? You'll want a I²S sound device to interface to the BeagleBoard/PocketBeagle that is supported by the ALSA SoC audio framework. Be prepared to build your own kernel and device tree overlays. Some microphone modules embed the I²S interface directly. - Cost? Consider using one of the analogue inputs from the on-board ADC with an electret capsule. Once again, be prepared to do some code hacking as you'll need to write a driver to read from the ADC and pump that into the ALSA framework (either through userspace or via a kernel driver). -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
