Macro: SpectCurve

This button pops up a dialog that allows you to apply a weighting curve to the data displayed in Y-log (power spectrum) mode.

The same dialog is opened by the Weighting Curve button in the Sound Level Meter option to select a Standard weighting curve, or a custom curve you create.

The top 'Y-log' button in the dialog is a duplicate of the button in the parent Spectrum dialog. You can also use ALT+Y to toggle this at any time.

A curve changes the displayed data (but not the raw data) as if an arbitrary-response filter had been applied to the original waveform, increasing or decreasing the response at different frequencies.

Curves have no effect upon linear magnitude spectrum or waveform displays.

Curves may be supplied as files, or you may use one of the built-in Tilt curves. Each channel may have only one curve applied to it at a time, but you may have a different curve for each channel. You can also apply the same curve to more than one channel.

• Weighting Curve Files
• Standard Weighting Curves
• Mirror Curve Files
• Tilt +3 dB / Octave (Pink Correction)
• Tilt +6 dB / Octave (Step Correction)

Macro Notes:

SpectCurve=1 opens the Spectrum Curves dialog, SpectCurve=0 closes it, and SpectCurve=x toggles between open and closed.

This command only works if the Spectrum dialog is already open.

Note that you do not need to open the Curves dialog to change its controls directly via macro commands.
