TIP? Taming Automatic Equalization

[DarkStar]

Sometimes when analysing two quite different audio streams in, for example, MAutoDynamicEq, can give some extreme results. As in:

You can reduce the impact of this EQ by dragging the Dry/Wet slider down (as the Help info says), but that still mixes the dry audio with some extremely-equalised audio.

I tried something-else: I 'learned' the 4 Gain values into a multiparameter (MP), with their ranges being from the calculated gain set by the equalisation engine down to 0 (for the negative gain values I also enabled 'Invert' on the MP Setting window):

Now I can change all the Gains at once, for example, here they are at about 21% depth:

Does that sound of any use to you?

...mmmmmmm...very interesting...gonnna' haft try that one...I use MADEQ:analyze all the time.../s~

I thought that the dry/wet already does that. I think it scales down the gain values rather than mixing in the dry signal. What makes you think the dry/wet works like that? Because the display tends to suggest otherwise.

[DarkStar]

Oops, it does - I didn't check that

Dry/wet defines ratio between dry and wet signals. 100% means fully processed, 0% means no processing at all. In normal mode only peak and shelf filters are affected correctly, other filters are left at 100% unless the ratio is set to 0%, in which case the equalizer is bypassed

So it doesn't mix dry and wet; indicates the 'depth' of the processing .

Even so, I've learned a bit more about the capabilities of these plug-ins

I know they are a gift that just keep on giving!
I like your thinking BTW I often create scaled MPs and the like.
I just wish I could scale convolution, but it only mixes dry wet.

Now there's a challenge

Given the way MAutoDynamicEQ and MAutoEQ are minimum phase, it probably wouldn't be the best idea for the wet/dry control to actually mix in dry signal. I'm sure Vojtech is aware of this, which is why he made it the way it is - where it acts as a proportional gain control for all bands.

Now there's a challenge

I've taken IRs of some EQs with bands at various frequencies and gain amounts. I just wish I could interpolate between them.

While we're on the topic, I'd love to see the addition of more than 7 bands in MAuto's matching section.

CurveEQ allows 60 points as seen here:

Do you own freeformEQ? That perfectly plots the frequency shape using it's auto function.

[mesaone]

CurveEQ is a spline equalizer, not a parametric EQ. By its very nature it requires multiple points to mimic the same curve as could be attained with fewer parametric bands.. Whether one is better than another is a matter of taste and application, but I personally don't see the need for higher than 7 bands.
