I have been looking at the various microphones and the graphs stop at 20KHz.
It appears that some of the microphones may have a rise gain as frequency increases.
The response does not need to be flat..... I can make adjustments

Yes, some of our microphones do have a high frequency resonant peak. For the ADMP504, that peak is at about 12 kHz, and for the ADMP411 and ADMP510, that peak is close to 20 kHz. The microphones all have decent response out to ultrasonic frequencies, but this is not something that we have characterized for any of these microphones so we do not have any data or frequency response plots that we can share.
Thank you based on what you have said... I will look at the ADMP411 and ADMP510 .... unless you recommend I start with some other microphone
You need SPU0410LR5H-QB - up to 80Khz - small and quite decent microphone, I use it for my ultrasonic stuff.
Retrieving data ...
