Version History & Changelog
v5.5.0 — Category 1 Core DSP Enterprise Engine
  • Dual-Rate Decimated Sub-band STFT: High-resolution 0.36 Hz/bin filtering below 1.2 kHz with only 42.6 ms latency.
  • True Stereo & Mid/Side Matrixing: Independent L/R and M/S matrixing; notch lateral room modes without collapsing phantom center.
  • Logarithmic Frequency Sliders: Start and End frequencies re-mapped to human auditory curves (50% of track covers 20–1000 Hz).
  • Pre-STFT Infrasonic DC Filter: 15 Hz Butterworth HPF removes sub-rumble and prevents Bin 0 normalization distortion.
  • Harmonic HF Damping: 0, 3, or 6 dB/octave attenuation slope mimics physical room air absorption.
  • Micro-Lookahead Limiter: 4-sample lookahead with smooth exponential decay completely eliminates clipping clicks.
  • Pure Allpass Disperser Mode: Breaks acoustic boundary reflections through temporal phase smearing without frequency attenuation.
  • Transient/Sustain Splitter: First-derivative energy detector allows percussive attacks to pass un-notched.
  • ERB Critical Band Spacing: Psychoacoustic critical-band notch spacing.
  • Live Q & T60 Metrics: Real-time display of physical Q factor and Sabine reverberation decay equivalents.
