: If frequency features are needed, apply an FFT or Wavelet Transform to each frame.

: Indicates the variability or spread of the signal's amplitude. : If frequency features are needed, apply an

: Quantifies the level of a desired signal compared to the background noise. Steps to Create a Feature Extraction Module : If frequency features are needed

: These describe the spectral content of the signal. They are usually extracted after applying a Fast Fourier Transform (FFT) : : If frequency features are needed, apply an
