Forums     Plugins     CurveEQ Spectrumatch inverse

This topic was created before release of the latest product version, and it may contain details irrelevant to this version.  Replying is disabled for this topic.

Aleksey discussed allowing an application of the inverse of of the match.

That is, capturing the spectrum of a voice, then matching it to an acoustic guitar, but instead, applying the INVERSE curve of what spectrumatch normally would.  It would reduce the frequencies in the guitar that are common between the guitar and vocal, and increase the frequencies that are uncommon.

Hopefulyl i explained it correctly.

I wanted this as well, and I eventually realized this can be done quite easily.  Simply create a spectrum match file created from solid white noise and apply that to the sound.  The resulting curve -- since the match feature is attempting to make it sound like a flat spectrum -- will be the inverse curve of the program material.

Actual application of the idea, I've found, unfortunately, seems to have limited results, since sounds are generally complicated and have resonances across the board.  Alas.  Nobody ever said mixing was easy.

Cheers.


I'll add a button.

It appears to me that the "white noise" part only does half the job.  It does not add/subtract the 2 source parts alone, it simply gets the curve of one, and applies the inverse to another.

My idea/suggestion makes that BOTH are considered, so that if both have a peak at 2K, it is not duplicated (as it would not in regular spectrum matching).

Do you understand the difference in what im saying aleksey?  Hoping that i can make this clear before you go and add it

in case you guys missed the guide on how to do it with the current version of curveeq already, i post the text from another thread in here:

Re: Curve Matching In Reverse

hi empty planet. no, its not the opposite way. look: take an sound, for example and bassdrum, now anaylze the original with CurveEQ and save that preset. now apply an Equalizer on exactly this same sound and boost some frequency about 12db or something very high. now go to CurveEQ again and analyze this modified sound as destination. you now see that CurveEQ makes a -12db at exactly this frequency, but instead applying this preset to the sound you modified, you now go to the ORIGINAL sound again and apply it there!! and what do we get as result now? the original sound now has a -12db dip at the frequency as the other sound with 12db has it as peak. and they both sit perfectly together now.  So this is exactly what you are looking for, a REVERSE curve! now you just need to do it as i described before. see what i mean? no need for such a switch.  Logical thinking roxx )

Regards.


It seems to me that Inverse EQ curve will do what you need, faster.  And since this is a very common function, I have added it anyways.

Aleksey, since this has been added.  Will you soon make a beta release with that addition?  It is very important to a project I am working on now.

thank you

Yes, I'll release this beta very soon (1-2 days).

@ Robert, CurveEQ has this feature now, but Inversing is inaccurate especially in the low end (its not the real invert curve, Aleksey also stated it does not), so the other way that was already described in the forum works alot better.
