Intro to Music Technology
Spectral Domain
FFT = Fast Fourier Transform
IFFT = Inverse Fast Fourier Transform
Transients = events that happen in audio
FFT = Frame Size
Ex: 1024 = 1024 samples in a frame
512
265
FFT = no time, Frequency Bins, and Magnitude (amplitude)
Size of each bin = SR/# of total bins
To get greater spectral resolution, give up time resolution!
The higher the frequency resolution, the less bins! And vice versa and more time.
