Hello Melda Production,

I decided to check out MAutoEqualizer last night and it's very nice. I noticed that the spectrum analyzer tracks three frequencies with the largest amplitudes, it tracks quickly and precisely. Is it possible to have the spectrum analyzer tracking frequencies tied to the EQ bands? The Manalyzer does this as well,l but I can't link the tracking frequencies to an EQ. Do you offer a product that can do this?

Thank you,

Rob

Hi Rob,

I'm afraid it is not possible and quite frankly I don't think you would want that. The results would be extremely unstable. However MAutoDynamicEq features several modulators, which can do pitch detection and there you can easily map to the bands, so that you will be processing the fundamental (or a harmonic, or just any frequency related to the fundamental pitch).

Thank you for your response,

Tracking and EQing the fundamentals is exactly what I want to do. I tried to figure out how to do pitch detection with MAutoDynamicEq and it EQ'ed out all of the fundamentals and a fair bit of the harmonics (a 3 sine wave frequency sweep). The frequency of each band wasn't dynamic, which is what I need. I think it would be simple to do with your plugin because it already tracks the 3 fundamentals perfectly, that's 90% of the work. Nice UI BTW!

Cheers,

Rob

Thank you Rob! Now, did you figure it out? I'm a little lost in your description, I'm not sure if it's ok or not :).

No problem, I should have been more specific.

I have created a continuous sine sweep that is modulated at 1/10 the frequency of the fundamental of the sweep. The sweep contains the fundamental and two side bands that are .9 and 1.1 times the fundamental, and about -6dB down from the fundamental. The purpose of this sweep is to detect intermodulation distortion in amps, sound cards and speakers. Typically the IM distortion is between -100 to -20dB below the fundamental, depending on the device under test.

After the sweep is recorded from the device under test, I'd like to remove the fundamental and side bands so I can compare the amount of IM distortion between similar devices.


MAutoEqualizer tracks this sweep but it will not dynamically change the notch frequency, it notches out the whole range of the fundamental. A competitors EQ tracks the fundamental dynamically, but for some strange reason they restrict the range from 30 to 2.7KHz.

As an added benefit, which I think most users would utilize, is a useful feature to dynamically enhance harmonics too. Tracking the fundamental, which can shift over time, and tuning the inharmonicity (harmonic non-linearity) of the EQ to enhance only the instrument related harmonics, keeps the sound natural and leaves more space for other instruments. Most harmonic enhancement EQ do not take inharmonicity into account and use textbook harmonic enhancement, which is close, but not as exact as it should be. For example take a note that has a fundamental of 440Hz, the first harmonic should be 880Hz but the reality is it's usually a slightly higher frequency (sharp) with stringed instruments. As you progress through each successive harmonic the sharpness increases. Anyway, I'm a bit off track but I think you get the idea.

Cheers,

Rob

Ok, so I'm a little lost here. What do you mean by "MAutoEqualizer tracks this sweep but it will not dynamically change the notch frequency, it notches out the whole range of the fundamental." ? First of all, we are talking about MAutoDynamicEq, right? And mainly "notches out the whole range of the fundamental"??? What does that mean? From the context it looks to me like you want to shift the frequency, but you can easily do that in the modulators, so I'm kind of lost.

I meant MAutoDynamicEq, sorry for the confusion. As far as modulators, are you referring to track automation or is there a function that I'm missing within MAutoDynamicEq? I tried the Automatic Equalizer function and it created a notch of the frequency sweep after I scanned the track.

NO NO NO! I meant the modulators!!! Ok, so please check this tutorial:



It's a little outdated, but the principles are the same. Basically you can make MAutoDynamicEq follow input pitch and set the bands automatically, no automation grrr :D

Ahhh, the modulators, I found them, they were tucked away behind a panel.

So I got it working and it tracks perfectly from 20Hz to 2K, then stops! I set the limits for the detector to 20-20kHz and the parameters fields to full range and 20kHz but it would not go beyond 2kHz, any idea why? Is there a way to override this limit?

Thank you

Post

Check the Pitch panel in the modulator ;). This limit is there because pitch detector needs some restrictions to avoid detecting harmonics, noise etc... This default range is correct for basically all real world instruments, but not for testing signals of course.

Hello,

Here are the setting I'm using, I already have the pitch detector maxed out, but it will not track beyond 2kHz. I'm using MDA Test Tone VST to generate a slow log sweep from 20-20kHz. Suggestions?

Aaaah, damn, you are right! It's the deharmonization. Simply put, the detector needs to remove the higher harmonics from the signal, otherwise it could pick a harmonic as a fundamental. But this process lowers the maximum frequency. Anyway I'll add it to to-do list for 8.03. We won't make it to 8.02, too late for that.

Aaaaah damn, haha.

If you're going to add the feature in 8.03 I'll go ahead and purchase the plugin, my trial is about to expire. When do you think 8.03 will be released?

I am also looking at purchasing MMultiBandConvolution, does this plugin have the ability to be a textbook convolution plugin? Meaning, it will just precisely convolve two signals out the nyquist frequency or close to the nyquist frequency of the host?

Thanks,

Rob

No idea really, this is rather extreme thing, so it definitely won't be featured on its own. So if you want the plugin just for that, please don't buy it yet.

About the MMultiBandConvolution - yes, it can do the precise convolution with any IR. But I really don't understand your description - how is that related to Nyquist?
