What I want to do

Determine the frequency of the generated wave of a Coqui device.

My attempt and results

AUDIO FILE → LS_51372.ogg

After recording the signal from a Bezoya bottled water and adding some salty water to it we've imported the file into Audacity. Getting this general wave.


Analizing a part of the wave

We've selected 1/2 second of the lowest signal (Bezoya water). You can do it directly on the timeline using the cursor or at the bottom of the interface.


Once selected, on the top menu go to "Analyze → Plot spectrum". For our low part of the wave we've got this curve.


For the high part of the wave (the salty water) this is the result.


Audacity has a lot of different patterns of analisis and options. Play around with it.

Questions and next steps

Use a know conductivity product and... modify the coqui with a potentiometer to "tune" this known conductivity signal to a musical note?¿ Would it be possible?

Very cool!!!! Haha for those new here, it's the Coquí, not the frog!

hahhahahah!!! added link to the very first line ;D
