I ran a bunch of experiments with a little wooden pressure chamber I made, working with the properties of the Cortado pickup’s piezo disc, in a surface-mount configuration.
I thought the data might be interesting for people here, plus I was goofing around and made this spiffy animated spectral analysis progression across the different configuration trials, so I wanted to post it around. 😀
First two graphs are control samples; here’s the key, and lots of details on exactly what I was doing. Sound file at the link, too.
