Show HN: Benchmarking Microphone Arrays

Hi, co-author here (and co-founder of www.snips.ai). We are building a voice platform for IoT which runs 100% on-device, because we don't want our devices to stream everything we say to a server.

At Snips, we've been using a bunch of mic arrays connected to Raspberry Pi devices, with various degrees of success. We realised that resources on the topic are scarce, so we decided to do a thorough benchmark of what we found to be the most popular mic arrays accessible to the maker community.

We'd love to have your feedback. If you have other microphone arrays you'd like us to include in this benchmark, let us know!
