Equalizer Graphics

I have transferred this FR and its vote to the Wiki today 14Jul08 - but retained this thread in the Forum, but relocated to Audio Processing - WC

This one should be pretty harmless.

I want pinstripes inside the equalizer work window to tell me where I am. Quick, point to a place 4 dB down at 7500 Hz.

No, I can’t do it, either, although I need to do it because that’s part of a complex curve I want to build. A much harder version of this involves two windows that read out the cursor position, similar to what happens in the analyzer. That would be a programming pain in the butt.

Either one would be welcome.

Check out the file “EQCurves.xml”

I’m not sure where it will be on a Mac, but in Linux it’s: home//.audacity-data/EQCurves.xml

They can be as simple or complex as you like. They can be edited directly and they are probably transportable.
Try copy and pasting these curve into your “EQCurves.xml” file:

	<curve name="ska">

		<point f="25.00" d="-2.9"/>
		<point f="30.00" d="2.6"/>

	</curve>

or a simple one

	<curve name="slope">

		<point f="800" d="-10"/>
		<point f="2000" d="-5"/>
		<point f="10000" d="0"/>
		<point f="24000" d="5"/>
	</curve>

or a high precision one
