Match EQ

Overview

The Match EQ module is a digital linear-phase EQ with the ability to use over 8,000 bands of frequencies for very precise matching.

The module interface includes the following sections:

1. Module Header
2. Spectrum and Matched EQ Curve
3. Reference Snapshot
4. Apply To Snapshot
5. Fine Tune

Match EQ Module Header

The module header includes the following controls:

1. Channel Processing Modes: Determines the channel processing mode for the module.
   • Match EQ supports: Stereo, Mid/Side, and Left/Right mode.
   • See the General Controls chapter for more information.
2. Reset: Returns all module controls to their default values.

   Note

   The Reference and Apply To curves are not cleared by pressing Reset.

Spectrum and Matched EQ Curve

The spectrum view includes the following features:

• Spectrum Analyzer (grey): Displays the magnitude (amplitude, in decibels) of a signal across the frequency spectrum in real-time. The spectrum analyzer in the Match EQ module displays the output signal of Ozone.
• Matched curve (white): The filter response of the matched curve. Represented by a thick white line drawn across the spectrum. This is only displayed after a Reference and Apply To snapshot have been captured.
• Reference Spectrum Snapshot (goldenrod): Display of the captured Reference snapshot.
• Apply To Spectrum Snapshot (blue): Display of the captured Apply To snapshot.
• Matched Curve Cutoff handles: Sets low and high frequency cutoffs for the matched curve processing.
  • Drag the cutoff handles to set lower and upper range boundaries for the matched curve processing. As you drag a cutoff toward the middle of the spectrum, the matched curve will flatten out to indicate no processing is being applied.
  • Click on the value readouts for the cutoff handles to manually enter a frequency value in the inline edit field that appears.
  • These can be useful when you want to concentrate on matching a particular region of the frequency spectrum. For example: apply the matched curve to the low end without affecting the high end.
• Spectrum Scales:
  • Spectrum Magnitude Scale: (dB) Vertical scale displayed on the left side of the spectrum view.
  • Spectrum Frequency Scale: (Hz) Horizontal scale displayed along the bottom of the spectrum view.
  • Matched Curve Gain Scale: (dB) The gain scale for the matched filter curve is located on the right side of the spectrum view.

Reference Spectrum Snapshot

Capture a spectrum snapshot of a reference or source track that you want to match your track to.

• Capture: Click and playback the track you want to use as a reference curve to begin recording a snapshot.
  

  Capture Reference panel playback

  If you want to use a track loaded in the Reference panel, enable Reference playback in the I/O panel and capture the Reference track directly from the Reference panel.

• Stop: Click to stop capturing and freeze the Reference spectrum snapshot.
• Clear: Clears the current Reference spectrum snapshot.

Apply To Spectrum Snapshot

Capture a spectrum snapshot of the track you are working on. The captured curve will be shown in blue in the snapshot view and spectrum view.

• Capture: Click Capture and playback your current track to begin capturing a snapshot.
• Stop: Click to stop capturing and freeze the Apply To spectrum snapshot.
• Clear: Clears the current Apply To spectrum snapshot.

Fine Tune

The Fine Tune controls can be used to adjust the shape and intensity of the matched curve.

• Smoothing: Determines the amount of precision to apply to the matched curve. Higher smoothing is less precise. Lower smoothing is more precise.
• Amount: Determines the amount of processing (intensity) to use when matching the Reference curve to the Apply To curve.
