High Slope Equalizers

[declassified]

I need an Equalizer that can be used to decrease the volume of a certain frequency by, say, -96dB.

It should have a very high filter slope per octave because I don't want to affect the other frequencies to much.

A notch filter is nice too, but they always seem to affect the nearby frequency ranges. Also, I'd like to have it as an paragraphic equalizer because I hate to work with the "Frequency", "Gain", and "Q" knobs of the parametric ones.

Any ideas?

Layer multiple EQs? You're gonna get quite a bit of phase shift by cutting that much. Maybe try linear phase eq by slim slow slider.

what are u going to do with such an high filter

[declassified]

Linear Phase EQ has WAY to less slope. It cuts away to much. The -96dB is good, though.

Layering multiple EQs doesn't solve it, either, because it wouldn't increase the slope.

I want to use the EQ for equalizing

[verstaerker]

i mean why do u need to lower/raise frequencies by 96db?

Sorry, but I can't discuss this on KVR. It has to do something with steal...errr...sampling, you know

Could you use "Tiny Splitter" from www.tinygod.com?

From Tinygod.com site:

Tiny Splitter:
Splits the incoming signal into three frequency bands. First out pair is lowpass, second out pair is bandpass, third out pair is highpass. Bandpass covers the range between the lowpass and highpass cutoff frequencies even if low and high cross over.

Route the three outputs to a mixer and mix away. (Use more than one in series if more bands are needed.) I don't know how the sound is otherwise affected.

'FreEq Boy' - Just what you want.

Nice, thanks!

But does it have to be such a CPU hog? It uses 20% on my AMD 2400+

Thanks Wide Boy - you got some steep slopes in there for sure. I've been using Cool Edit/Adobe Audition to split out freqs prior to your plug - much easier with FreEQ Boy!

One thing I've noticed in Sonar4 though...I have a steep slope set at about 80Hz creating a low pass filter (I'm soloing part of a kick drum in a full mix), when I double-click on FreEQ Boy so Sonar4 will bring up the FreEQ Boy gui for a brief moment the entire freq range plays then after 1 second the filter kicks in and I only hear the 80Hz lowpass. This doesn't affect mixdown or any other track rendering - I didn't check to see if automation is affected. Clould be a minor glitch in there Paul?

declassified - are you sure about the cpu utilization coming from FreEQ Boy - I'm running it on a 2.6GHz P4 and I'm getting 4%-6% utilization from FreEQ.

Thanks for the plugin & discussion guys - just what I was looking for today for a huge multiband experiment!

From V1.08 onwards, I completely rewrote the processing using optimized assembler based routines. The CPU usage from that point onwards is significantly lower. You can read more about this at:

Which version are you using? If you got a version that came free with another of my plugs, I stopped supporting those a while back. The current commercial release version is at V1.12.

As you may know, I have been in the process of improving compatibility of all my plug-ins wrt SONAR. 'FreEq Boy' is the next on the list. I will probably have a new version by next week.

Oops - I just noticed I forgot the version...yes it's the free one - 1.09w. Let me pick up the commercial version then, it's very economical and will save me a lot of time when I need a steep steep slope - plus I can alter them on the fly while mixing/mastering which I can't do using the off-line Cool Edit Frequency Splitter.

Thanx Paul

Forgot to mention - I will also convert 'FreEq Boy' to a transferable license on the next update.
