Interesting! Especially cause in my new sound localizing raspberrypi project (<a href="https://github.com/hcfman/sbts-aru">https://github.com/hcfman/sbts-aru</a>), generalplus USB microphones are one of two I’m recommending here. (That and cm108 based ones).<p>The generalplus ones have a bit more gain capability. I “think” that the generalplus ones might be a little newer than the cm108 based ones.
