[QUOTE="Merlijn van Veen, post: 96400, member: 4708"] Re: Sim VS Smaart To clarify my previous reply, I've attached a picture illustrating the differences regarding time constants. I got the values from SMAART 7 by observation. SIM3 uses 8 time constants SMAART 7 uses 6 time constants. To me, the interesting part is the lower and upper frequencies of each span expressed in multiple wavelengths of the time constant. According to Bob McCarthy, signals arriving within 6 wavelengths are considered tonal, within 24 wavelengths spatial and anything beyond 24 wavelengths echos. As the amount of wavelengths increases the usefulness of equalization decreases and the need for alternative solutions rises. Anything arriving past the time constants is considered incoherent and shouldn't be equalized. I feel the choice of time constants is one way how in this case, Rational distincts itself from Meyer Sound. [I]"We chose, as our default, to use multiple time windows as we had done in the past.
