Single-Band EQs

The sections below provide descriptions for the following Soundtrack Pro single-band EQ effects:

High Cut and Low Cut Filter

The Low Cut Filter attenuates the frequency range that falls below the selected frequency. The High Cut Filter attenuates the frequency range above the selected frequency. Use the Frequency field and slider to set the cutoff frequency.

Figure. Low Cut and High Cut Filter windows.

High Pass and Low Pass Filter

The High Pass Filter affects the frequency range below the set frequency. Higher frequencies pass through the filter. You can use the High Pass Filter to eliminate the bass below a selectable frequency.

In contrast, the Low Pass Filter affects the frequency range above the selected frequency.

Figure. High Pass and Low Pass Filter windows.
  • Frequency field and slider: Sets the cutoff frequency.
  • Order field and slider: Sets the filter order. The more orders used, the stronger the filtering effect.
  • Smoothing field and slider: Adjusts the amount of smoothing, in milliseconds.

High Shelving and Low Shelving EQ

The Low Shelving EQ affects only the frequency range that falls below the selected frequency. The High Shelving EQ affects only the frequency range above the selected frequency.

  • Gain field and slider: Sets the amount of cut or boost.
  • Frequency field and slider: Sets the cutoff frequency.

Parametric EQ

The Parametric EQ is a simple filter with a variable center frequency. It can be used to boost or cut any frequency band in the audio spectrum, either with a wide frequency range, or as a notch filter with a very narrow range. A symmetrical frequency range on either side of the center frequency is boosted or cut.

  • Gain field and slider: Sets the amount of cut or boost.
  • Frequency field and slider: Sets the cutoff frequency.
  • Q-Factor field and slider: Adjusts the Q (bandwidth).
