Hi all,

I’m new with the arduino and im trying to do an FFT using the music labs library. (until now nothing makes sense). My final objective is to be able to store a 1500:1 size vector, and then perform an fft in that vector, and then do an inverse fft. First question, does this library allows me to do an inverse fft?

Ive been playing with the basic example provided (fft_adc) but i dont really understand what it is doing. specially what is the output supposed to be and how im i supposed to see it? I put a 4 khz sine in adc0, and checked out the serial monitor but all I saw is random characters, Im not sure whats that also I noticed the serial monitors baud rate is set to 9600, do i need to change that to 115200 to match the code?

I would really appreciate ANY help! thank you so much!
