Equalization

[Macdelf]

The new equalizers in Moode 7.0 are fantastic, however I would like to go one step deeper.

-Where are the resultant equalizer files stored?
-Are they in the frequency domain, or time domain (impulse response)?

I would like to generate a custom amplitude and phase equalization (or its corresponding impulse response) and somehow implement it. This is to mimic the response of a Sallen Key highpass filter with a Q of 2. These were used with old B&W matrix loudspeakers (e.g. 801, 802,...).  Amplitude is easy with the current set up, but phase is unknown.

Knowing the location of the files (and potentially their format) will make this possible. This would also tell me exactly what the equalizer is doing.

I think I got the method down and given the wonderful new capabilities Moode 7.0 offers it should not be too difficult. Looking at https://www.bitlab.nl/page_id=634 and the Camilladsp pages it is possible to enter an impulse response filter, or even simpler a high pass filter with desired Q. I take it that the equalizer performs a convolution with the impulse response as the dit stream is generated. I also believe that the filters are transformed internally to create that impulse response making the job much simpler.

I don’t know if anyone else is trying to get camilla to wok, but I have hit a snag. After replacing the device alsaequal with camilladsp I get “device not found”. Any advice is welcome.
