Frequency

Frequency is a high-quality equalizer with 8 fully parametric bands. The bands can act as either shelving filter, as peak or notch filter (band-pass), or as cut filter (low-pass/high-pass).

Main Layout

Alt-click this button to reset all parameter values.

Auto Listen for Filters

If this option is activated and you edit a parameter of a band, the corresponding frequency range is isolated. This helps you to focus on a particular frequency range and allows you to locate unwanted frequencies in your audio.

Global Settings

Opens the settings dialog for the spectrum display.

Show/Hide Keyboard

Shows/Hides the keyboard below the graphical editor.

On the keyboard, color indicators reflect the center frequencies of all active equalizer bands. You can adjust the frequency of a band by dragging its color indicator. If you drag the color indicator of a band to a key, the band is set to its exact frequency.

Output

Adjusts the overall output level.

Band Settings

Activate/Deactivate Band

Activates/Deactivates the corresponding band.

Note

  • To activate/deactivate a band, you can also double-click the corresponding handle in the graphical editor.

  • If a band is deactivated, you can still modify its parameters.

Switch Processing

Allow you to switch between left/right, stereo, and mid/side processing. In Left/Right or Mid/Side processing mode, you can make different settings for the two channels.

Important

When using Mid/Side processing mode, we recommend that you activate Linear Phase in order to avoid unwanted sound colorization.

Note

This setting is only available for stereo tracks.

Linear Phase

Activates/Deactivates linear phase mode for the corresponding band.

Linear phase mode avoids unwanted frequency dependent phase shifts of the audio signal that might occur with standard minimum phase equalizing.

Note

  • Linear phase mode leads to an increase in latency.

  • In rare cases, for example, when using low cut filtering with a high slope for bass signals, also an unwanted pre-ringing effect may be audible.

Filter type

You can choose between the filter types Low Shelf, Peak, High Shelf, and Notch. For band 1 and 8, you can also select the types Cut 6, Cut 12, Cut 24, Cut 48, and Cut 96.

  • Low Shelf boosts or attenuates frequencies below the cutoff frequency by the specified amount.

  • Peak boosts or attenuates frequencies at the set frequency value with a bell shaped filter.

  • High Shelf boosts or attenuates frequencies above the cutoff frequency by the specified amount.

  • Notch boosts or attenuates frequencies at the set frequency value with a very narrow filter.

  • Cut attenuates frequencies below (band 1) or above (band 8) the set frequency. You can choose between different slopes: 6 dB, 12 dB, 24 dB, 48 dB, or 96 dB per octave.

Freq

Sets the frequency of the corresponding band. You can set the frequency either in Hz or as a note value. If you enter a note value, the frequency is automatically changed to Hz. For example, a note value of A3 sets the frequency to 440 Hz. When you enter a note value, you can also enter a cent offset. For example, enter A5 -23 or C4 +49.

Note

  • You can adjust the Freq parameter of a band in the graphical editor by Alt-clicking the corresponding handle and moving the mouse left and right.

  • Ensure that you enter a space between the note and the cent offset. Only in this case, the cent offsets are taken into account.

If the band is active, the frequency value is reflected as a highlighted key on the keyboard below the graphical editor.

Q

For Peak and Notch filters, this parameter controls the width of the band. For Low Shelf and High Shelf filters, it adds a drop or a boost, depending on the gain setting of the band. For Cut filters, it adds a resonance.

Note

  • You can adjust the Q parameter of a band in the graphical editor by Shift-clicking the corresponding handle and moving the mouse up and down. Alternatively, you can point on the handle and turn the mouse wheel.

  • This parameter is not available for Cut 6 filters.

Gain

Sets the amount of attenuation/boost for the corresponding band.

Note

  • You can adjust the Gain parameter of a band in the graphical editor by Ctrl/Cmd-clicking the corresponding handle and moving the mouse up and down.

  • This parameter is not available for Cut filters.

Invert Gain

Inverts the value of the gain parameter. Positive gain values become negative and vice versa.
