I'm logging the RPM of a scaled wind turbine using a laser and modified microphone (with a photocell instead of a coil).
The signal is recorded using Audacity and is a series of troughs separated by the time it takes for one blade to pass through the beam (please see attached image below).
Is there a way to convert this signal into an array of time-stamps and signal strengths (0.0 to 1.0)?
I aim to eventually have a time vs. instantaneous RPM plot.
