Good evening.
I have to measure the fundamental frequency of a wineglass from the Amplitude versus Time data. I would like to know if you could give me a suggestion or help. I have used "Audio Spectrum", and implemented an FFT code to find the fundamental frequency from this data, however, my results are not what I expected.
I don't know if I should really use "Audio Spectrum" or another function. I also think that I should measure the vibrations and thus find a graph of "Amplitude versus Time", in which case I am not sure how I should position my smartphone in relation to the wineglass.
I am looking forward to your response. Thanks in advance.
Oh! Thanks for the app, it's amazing!!
