Algorithm features high and low frequency exclusion from main lookahead, for a bit more pronounced highs, and firm analog lows. This improves intermodulation in the main lookahead also, which does a mix of 1 and 2 lookupbuffers, with filters in between for optimal sound. Main lookahead filters also features phase-coherent saturation." Peace Be With You.
