Hi,
Maybe you already use volspimpleequal, a 10 bands graphic equalizer.
Now, if you want to equalize in an more “professionnal” way, I 'm proud to present “volparametriceq” a 4 bands parametric equalizer based on EqFA4 quitte.de/dsp/caps.html#EqFA4p
This a beta version. Feedback welcome !
The main target of a DSP is to manipulate the signal. So it can’t be bit perfect.
But, being bit perfect does not means it is good.
Suppose you have a poor amp, or poor speaker, or even a room that sounds bad, a bit perfect can’t improve the sound. But a equalizer or a room correction can do it!
Hi plugin looks promising however I think I have an issue with saving state. Steps to reproduce: change mid high db param, then leave config page and enter config again you will notice dB param resets to 0 instead of selected one.
Btw. what do you think about adding one additional “switch” to enable/disable all properties (“flat mode” without equalization) ? It would be nice to get a possibility to hear “current” preset in comparison with flat setting by single button press.
Hi!
You’re right. I will correct it asap!
For your suggestion, why not. As you are the first user to post a feedback, I thought that the interest for the plugin was zero…
But there is some other problem I need to solve.
What is the device you use? What is the dac (i2s /usb / integrated)?
I keep you in touch for the correction.
edit : I updloaded a new version with correction for unsaved parameter (+ some inside modifications)
edit 2 : now a switch allows to enable / disable effects of the equalizer. You have to apply to hear the diff…
1) Allow to user to save presets
Yes I’m thinking of that. I was waiting for a user… Don’t know yet how I will implement this because of some restriction in the webUI
2) Total control over frequencies, Q values, and dB (i.e. 1234Hz, 1.32 Q, -1.5db)
No sure to understand… You mean for each band having the full frequencies ranges ? (20Hz to 20Khz ?) Not easy because we need a little step for low freq and a biggest for high freq. Not esasy with a slider…Or maybe with a text field in which you enter the value. Or can you be more precise ?
3) Allow the first and last band to be shelving controls
Not possible as I use quitte.de/dsp/caps.html#EqFA4p . And I’m not able to write a other lib…
Maybe if I find a other ladspa plugin with this…
4) Perhaps add an extra band?
Not possible as I use quitte.de/dsp/caps.html#EqFA4p . And I’m not able to write a other lib…

Please do not hesistate if you whish/need other features/corrections
There’s another user
Thank you - the plugin does a good job in my bathroom where small speakers do their thing and require correction more than “bit perfection”.
For example, on the high band, the selectable values are 1000 Hz apart - 8000, 9000, 10000, etc. On the mid-high band, they’re 500 Hz apart - 7000, 7500, 8000, etc. It would be amazing if you could dial in an exact frequency on all bands. Either the sliders could be continuous and you just drag them to the exact frequency you want, or perhaps a text box instead of a slider.
It would be really great and flexible to be able to select exact frequencies (like 8285 Hz), exact decibel values (like a 3.5 db cut), and exact Q values (like 1.32), and likely a text box would accomplish this. Parametric EQs require a bit of assumed knowledge anyway, so I think users of a parametric EQ would actually appreciate text boxes instead of sliders.
Again, great work! Its just that some headphones really shine when you can dial in an exact parametric EQ, and that would be such an awesome thing to have.
Hi!
I just uploaded a new version with a more precise step for the different parameters. I can’t use smallest step because my mouse is not precise enough to select them !
low - 30-125hz step 1hz
mid low - 100-2000hz step 5hz
mid high - 1500-9000hz step 20hz
high - 8000-14000hz step 50hz
thanks for your great work. The plugin by itself works great on my setup. Just one question, can I also combine it with another plugin, e.g. the stere2mono plugin of yours? (which works great on its own too, btw.)
