FR - MTransformer - Bypass above effective range

[vectorwarrior]

MTransformer remaps the frequencies to whatever you want, however it only goes up to 20khz, anything above that gets deleted as this is as high as the frequency transformation graph (the left one) goes. If you have any material above this limit, it gets deleted. For most people this isn't important, but for some of us who work in more esoteric sound design (game/film/weird stuff) that content can be important, maybe I want to pitch the output down later, etc. By deleting this high frequency content, I am essentially 'locked' to using the output at that pitch if I want to keep a full frequency signal.

My request is that anything above the cutoff (which i believe to be 20khz) is passed through to the output untouched. This way, only the frequencies you can transform are effected and you are safe in the knowledge that anything above this range is clean.

Below you can see the result of an MTransform process on a 96khz file that DID contain signal before the process, notice the dark patch above 20khz and the sudden cutoff in that range:

Below you can see a vertical frequency zoom of the the exact area where the cutoff happens:

Thanks!

-nvm totally misread the post-
You could do that manually run a parallel effects chain with a steep high pass at 20khz.

Yeah, I know that I could do this in mxxx easily, but I'm saying that it should do it by default. I think most people would be surprised to hear that it deletes information above 20kHz and given that you don't get any control over that range you would want it left unaltered.

I personally think it would only add more to the confusion, you'd get holes in the spectrum etc.

[vectorwarrior]

Yeah, you're probably right. I can see how if you do a big pitch down, having some material still up high would be weird.

With that in mind, my preference would be for a button called 'ignore above max frequency' or something like that, this way you have the choice. There are similar buttons for low frequency stuff in a few of the spectral effects.

Actually it's part of the design and there needs to be a limit. It could be Nyquist, but in most cases it's far better to do it this way. Why would you need the stuff above 20k survive?

[vectorwarrior]

As I said in my original post, I may pitch down (with varispeed) sounds afterwards. The current process effectively sample rate reduces the output down to 40khz, making this highly undesirable. As pone suggested though, I can set up a crossover in MXXX to bypass the signals above, that's really easy to do so I'll just do that instead. I know I'm in the minority in caring about this stuff (I work with sound effects not music).

Aaaha, I understand. Well, that's really "extreme" . Anyways I'll check.

Not really. A lot of 'raw material' sample libraries aimed at film/game/media sound designers are recorded at 96Khz or 192Khz for this very reason.

Just in case the OP missed it, this has been added in version 10 of the Melda plugs.

[vectorwarrior]

Yeah thanks, I tested the alpha and it works perfectly. Very happy
