What constitutes an activation? I currently use correction filters, of length 262144 samples in the .dbl format, in my convolution computer. Will the software handle this? Tony

I prefer greater flexibility than provided by most A/V hardware and use Acourate to generate correction filters and provide time alignment. I use 30th order Bessel filters (no pre or post ringing) with a crossover at about 90 Hz. The high pass filter rolls-off at 6 dB per octave and so I...

First a real-life story. Many, many years ago, when I was using Tact 2.2Xs in my system, I sensed a problem with the correction and, as a result, I spent a lot of time on measurements and analyses to understand why. It turned out that the Tact was performing no correction in the frequency range...

The measurement was made many years ago. I can't remember exactly when but the file, which I considered as non-essential, was lost in a major computer system failure. At the time I was only interested in a 30 dB range but I am sure that extending the range would start to show low level garbage...

You are correct in thinking of using tuned bass traps. This is really the only way to address resonant modes (other than active cancellation). If you have the space very thick broad-band absorption helps to some degree. To give you an idea of what can be achieved in a relatively small room I...
