Sonic Sweep 2: Three-Channel Console EQ and Bus Processor

Each of the three channels includes a Hi-Mid band covering 500 Hz to 18 kHz and a Lo-Mid band covering 45 Hz to 3 kHz. Both are fully parametric, with bandwidth continuously variable from 3 octaves down to 1/12 octave. Dedicated 12 kHz and 80 Hz shelf EQs and a 75 Hz, 18 dB/oct Chebyshev low-cut filter complete each strip.

Rave Generation describes the analog stage as multi-stage soft-clip amplifiers with +26 dBu headroom, NJM4560 op-amp slew rate limiting and calibrated transformer drive. Console Age adds asymmetric distortion, and Console Noise adds hiss, 50 Hz hum and slow drift for a less static sound.

The Parallel-Serial blend lets you move continuously between parallel summing and serial, daisy-chained processing. An equal-power crossfade handles the transition, and shared post-blend shelf filters keep phase coherence across routing modes.

Oversampling is selectable in three modes: CO at 1x with zero latency, NORMAL at 2x and HIGH at 4x, all using Kaiser-windowed FIR anti-alias filters. NORMAL and HIGH apply automatic latency compensation. Gain X2 extends boost and cut to ±30 dB, Freq X2 doubles the sweep ceiling, and EQ Flip moves the EQ before or after the clipper. All filters run at 64-bit double precision.
