Hello,
i have the following problem and I need to sort it out
A SD card contains a wav file with a train of audio pulses with changing pulse durations. (It was received from a balloon tracker by a radio receiver. So the pulses can be noisy.)
After storing the wav in the arduino buffer, the arduino should process the pulse train such that it provides the pulse duration for consecutive time steps. The emerging data then should be stored in a separate file
Is there a way to use the built-in function pulseIn() for this purpose? How can one process a wav file in the described manner?
Any input or idea is welcome
