Mirrored Spectrogram images in python #24

Open jouleion opened 2 months ago

jouleion commented 2 months ago

This might be due to wrong indexing in the Arduino code. (this makes the old spectrograms invalid) Or this is wrong loading in python. (this is better)

might be fixed with new serial sending code, have to look it up though

this is not due to bad indexing or bad reading in python. but an artefact of doing fft. it is mirrored around the niquitecent frequency, which is half the sample rate. 2000 / 2 = 1000 Hz
