话题: Isolate frequency range

由于该帖子已年深日久，可能包含陈旧过时或描述错误的信息。

Does anyone know how (in C/C++) to get only a certain frequency range (i.e. either Bass, Mid or High), to apply an effect only on those frequencies?

Thanks

Ho, huge problem.

It is a problem of signal processing but you may find some to code about filtering frequency on DSP and C++ websites.

Do you know any particularly good website about DSP signal processing and C++?

Actually, what I want it to change the volume of only one of the three frequency ranges that we can modify in VDJ, according to a formula. I can do it by sending commands to change the slider's position, but I was looking for something faster and that didn't require a powerful computer.

Lol, so you should still doing it with the command of the embedded equalizer.

All this processing require cpu power.
If you make it yourself in a plug_in you will not go faster and you will require more cpu power as the EQ of VDJ still working.

If you want your sendcommand to be processed as soon as possible, just use the value -1 as "when" parameter.

If you can read french, have a look here:

If not, you can try an automate translation with google.

You can find links in the bottom of the page.
