Re: Combining crossover types

Yes. You have to properly combinea high-pass with a low pass.

Re: Combining crossover types

Matt,

instead of SplitNJoin you can also try convolution followed by a symmetric CutNWindow. It should be more precise.

Re: Time alignment of drivers in active multiway speaker systems

Matt, the measured pulse also contains information e.g. about the sweep start and end frequency. You can consider a mid driver measured from 1 kHz to 6 kHz as a driver measured from 0 Hz to fs/2 but with an applied steep bandpass filter 1 to 6 kHz. Thus the pulse response also contains properties of...

Re: FD Magnitude sum

Imagine both channels are properly playing. Thus the time domain addition will lead to amplitudes increased by factor 2 = 6 dB. Now imagine that one channel has a phase rotation of 90°at a given frequency, e.g. 200 Hz (see you curves). This means that the amplitude sum increases just by 3 dB. Now wh...

Re: FD Magnitude sum

The magnitude as result of a Fourier-Transform does not contain time information anymore. Thus the sum of the magnitudes will clearly change phase and pulse response. So you can select between a linearphase or minimunphase result. Any yes, the magnitude (= not signal amplitude!) is shown with logari...

Re: Macro4 & ICPA

It is necessary to have some filters defined and enabled in ICPA (macro6) before macro4 can use the ICPA function.
Similarily the prefilter checkbox is greyed out if there is no prefilter existing.

Re: Combining Virtual Bass Array and Alternative to VBA Pre-filters

So I have always wondered if I should be less obsessive compulsive and just relax and simply enjoy the music more. Each one of us has to find his own way. I have followed the discussion but not stepped in. IMO you are on the right path so far. But I just like to add some thoughts: After a while of ...

Re: Optimizing speaker distortion

Hello Dalton, I see at least 2 points in your picture: 1. the logsweep data are not detected. The correct steps are: - record pulse responses by the logsweep recorder. The recorded sweep is also saved in the workspace - run the manual logsweep convolution and select the saved recording. Deselect Ext...

Re: Acourate Version 2 is Fantastic

I'm very sorry, there is no discount. V1 has stopped.
BTW what about audio equipment in Brazil? Is it so much cheaper then here?
