digital room correction

[Veggen]

Agreed, the EQ is a very broad-brush approach. This is mostly because my perl skillz aren't yet equal to the task of making a good user interface to proper parameteric-type EQ. You may find easiest to edit the settings file by hand:
- Use the remote control to get EQ settings approximating what you want
- Save as a preset "xxxx"
- Look for the preset file xxxx.preset.conf (in \Documents and Settings\All Users\Application Data\InguzEQ\Settings)
- Edit this file with a text editor. You can change the frequency/gain settings or add as many as you want; just be sure they're in ascending order, and that you keep the XML tags in matched pairs.
- From the remote control: load this preset again.

To approximate a notch filter (although the shape of the frequency response will be a cosine, not a real notch), just have two 0dB frequency points either side of the notch, and set your notch value to (say) -9dB or -12dB.

Sounds good, but I am not able to get it to work.
I have tried making a customised 9 band preset for flattening out the low frequency response of my speakers. The EQ part of my .preset.conf file looks like this:

<EQ Bands="9">
<Band Freq="1">-12</Band>
<Band Freq="10">-12</Band>
<Band Freq="20">-12</Band>
<Band Freq="30">0</Band>
<Band Freq="40">8</Band>
<Band Freq="50">6</Band>
<Band Freq="60">4</Band>
<Band Freq="70">2</Band>
<Band Freq="80">1</Band>
</EQ>

After selecting this preset in the EQ menu, my .settings.conf file changes to this:

<EQ Bands="9">
<Band Freq="60">4</Band>
<Band Freq="120">0</Band>
<Band Freq="240">0</Band>
<Band Freq="480">0</Band>
<Band Freq="960">0</Band>
<Band Freq="1920">0</Band>
<Band Freq="3840">0</Band>
<Band Freq="7680">0</Band>
<Band Freq="15360">0</Band>
</EQ>

It defaults back to the standard 9 band frequencies and seems to ignore all other settings.
So what am I doing wrong?

The first 4 lines is an attempt to filter out subsonic frequencies to cut out low rumble and ease the job for the amp and speakers.
Should this work?
Is there a better way of blocking all frequencies below 40Hz?
Can dB values smaller than -12, or larger than 12 be used?

Also I have tried using a 15 band EQ, but that just changed into 2 bands.

I am using the newest plugin dated 2nd january.
At his point I am only using the EQ part of the plugin, I will implement room corection shortly.

Any suggestions would be most welcome.
Anyone else got this to work?

The "flatness" control defaults to 10, but if I set it to something else, it will reset back to 10 every time. Is this meant to happen?

Veggen>> Sorry, I was wrong. You can write a custom <xx_xx_xx>.settings.conf file and the equalization filters will be constructed accordingly; but as soon as you go to the plugin (EQ menu on the remote) it'll stomp on it. I'll look to do this properly in a release soon.

CFP>> No, that's not meant to happen. It's only supposed to default to 10, not get stuck there forever. Looks like a bug - sorry...

[Veggen]

OK thanks for the reply.
Just to check I understood you correctly: As a workaround, until you fix the plugin, is it possible to edit and save the <xx_xx_xx>.settings.conf file directly?
Will this perform the equalisation as I want it to until I go into the EQ menu again?

Also how about the low frequency filtering, any suggestions how to do that?

[inguz]

Yes, a low-frequency filter set like the one you posted should work fine, editing the <xx_xx_xx>.settings.conf file directly.

Hi ,

I have just installed EQ and it's not working with .ape files .
I only check the Monkey's Audio FLAC mac/InguzDSP box and no sound. Any idea ?

EQ support just FLAC and WAV ? it'true ??

If Inguz didn't support it, I'm sure Hugh wouldn't have included a check box for that file type. However I don't have any files in that format so I haven't tried it myself.

Does it work with FLAC and WAV? There's a log file you can check; it's in Documents and Settings/All Users/WinNT/Application Data/Inguz/log.txt or something close to that path (I don't have my PC in front of me but you should be able to find it).

Sorry; bug. Fix on its way soon.
