Hello,
There are some data which are not in a wav file, such as | 1 0.2 0.4 -0.3 0.3 0.2 0.6 0.5(, I want to calculate the FFT of these data. If I use sig~ to put these data into signal, then I use fft~, it can be run, but the result is wrong. How can I calculate FFT with some data correctly?
Thanks!

Hi, you can copy data into an array of fft length, then send to the fft object via [tabplay~]. Write the spectrum parts or amplitude spectrum into another array with [tabwrite~].

Good. It can work correctly. Thank you!
