How is FFT used in audio processing?

The "Fast Fourier Transform" (FFT) is an important measurement method in the science of audio and acoustics measurement. It converts a signal into individual spectral components and thereby provides frequency information about the signal.

What is FFT size in audio?

The FFT size defines the number of bins used for dividing the window into equal strips, or bins. Hence, a bin is a spectrum sample , and defines the frequency resolution of the window. By default : N (Bins) = FFT Size/2. FR = Fmax/N(Bins)

What is audio data augmentation?

Data augmentation definition :

Data augmentation is the process by which we create new synthetic training samples by adding small perturbations on our initial training set.
