Interesting! What about bandwidth and linearity compared to ECM's?

Bandwidth and linearity are each both worthy of their own discussions, but I think that you'll find similar bandwidths of operation for ECMs and MEMS microphones. Many MEMS microphones today have a maximum SPL (clipping point) of about 120 dB. There are certainly ECMs available that are linear to higher SPLs, but again, those are often larger, pro-level devices. I think that we'll start to see more MEMS microphones that are linear to even higher SPLs in the future.
