fix pbe/haas surround dsps: surround_enabled, redo flush functions. 2015-01-22T02:28:34+00:00 Chiwen Chang rock1104.tw@yahoo.com.tw 2015-01-22T02:24:15+00:00 30784cc262a4ee34f73c25704e19905c1be9998e surround_enabled was never true, end up dsp_surround_flush didn't work; Thats why a cracking noise occurs in right channel when moving track positions. redo pbe/surround flush in a much simpler way suits the current single buffer style.

perceptual bass enhancement
- a bbe-ish group delay corrction with Biophonic EQ boost.
- precut

auditory fatigue reduction
-reduce signal in frequency that may trigger temporary threshold shift

haas surround
-frequency between f(x1) and f(x2) is always bypassed.
-can apply to side only.
