626be18da0 [Bug Fix] haas surround use delay_ms instead of index surround_strength
this appears to be an old bug

rather than using an index use delay_ms directly

49a2953ade surround: Fix two issues with the haas surround code.
1) Handle ID 0 is legal
 2) Make sure handle is initialized before trying to memset its buffer

5eee28e37d Nitpick configuration code in a few DSP filters to fix some bugs
Most importantly is surround shouldn't operate in mono mode. Have it
watch and (de)activate itself on relevant format changes as it should.

Other changes to better handle buffer allocation failure.

PBE was set internally at 100 by default; SBZ.

30784cc262 fix pbe/haas surround dsps: surround_enabled, redo flush functions.
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.

3ae0f32ac3 three new DSPs
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.
