Redesigned waveform rendering with smooth triangle-strip ribbons and tapered end caps. Added frame-to-frame interpolation for fluid, jitter-free waveform animation. Auto-detecting stereo mode with left/right channel split display. Circular mode: animated zoom tunnel trails. Flurry mode: improved audio responsiveness with asymmetric attack/decay and peak detection. Optimized GPU rendering path across all visualization modes. Fixed circular waveform seam alignment with amplitude changes. Resolved cross-thread data race in waveform buffer updates. Improved high-DPI rendering with wider, more visible waveform lines. Reduced visual noise in glow ribbon width and opacity. General rendering stability and performance improvements.
Early Schroeder reverberators consisted of the following elements: a series connection of several all-pass filters, a parallel bank of feedback comb filters, a mixing matrix.
