These are some of the worst clicks and artifacts I've ever heard. A zoom in on the waveform revealed hideous spikes of very high frequency. You really have to preview your entire program before commiting to this process. It seems to be very powerful with a great number of adjustable parameters. However, all these parameters have made it a bit difficult to get a hold on.
Bonus is that there are a bunch of setups which come with it.
So I am sure it is a product that requires a lot of use and experimentation to perfect. To truly copy the BBE, the crossover points are 150 Hz and 1200 Hz. The low band is delayed 2.5 ms and the mids are delayed 0.5 ms relative to the highs. This phase compensation is intended to pre-correct phase distortion of loudspeakers. The Aphex is harder to simulate, since it is a harmonic generator.
