Spectral Response

This lesson explains the spectral response of a signal. A spectral response is audio seen in the frequency/amplitude domain and seen here through use of FFT (Fast Fourier Transformation).

Filter Types

This lesson explains the various filter types we can find in equalizers. Most common ones are Cut/Pass filters, Shelf filters, Bell filters and Tilt filters.

Filter Parameters

This lesson explains the parameters given for each common EQ filter. These are usually: frequency, resonance / q, amplitude and slope.

Practical Example

This lesson shows a practical example of how an equalizer can be used.
