Quantec IR - I tought of Impulse Response, the convolution thing. For sure it is noisy tho it is bandpass noise cause 18khz processing = 9k thruput :)) Bout sonalksis blokes: "The audio signal processing technology developed by Sonalksis is the result of extensive research by ourselves, in collaberation with academics and music industy professionals. Indeed many of our algorithms would not have been possible even 5 years ago, as they build upon research at the very forefront of digital signal processing theory." And Neve (..group of companies) made the first commercial digital console,tho not sold well, but the result , the smaller DTC has its effect on CD production, so rather let's say that, there is quite a lot percentage to it that youve heard it already! The head of Weiss engineering (top end equiptment) said, that the thing got him into engineering was in fact the DTC (one of the few "serious" devices what did the justice). And here is this decade between bitslice processing and ADSP Sharc too.
