The Prompt-to-DSP
Mastering Architecture
Kharivox eliminates human studio bottlenecks and lossy streaming degradation through automated multi-agent state machines, local GPU neural stem separation, precision Butterworth filtering, and strict LUFS compliance.
Signal Flow & Audio Architecture Graph
Mastering DSP Specifications & Mathematical Bounds
Butterworth Subsonic Cut (28.0 Hz)
Sub-audible DC drift and acoustic rumble below 28 Hz waste amplifier headroom and generate intermodulation distortion in high-power playback transducers. Our Butterworth 4-pole highpass filter purges inaudible frequencies with maximally flat passband response and zero resonance peaking.
Ultrasonic Lowpass Brickwall (15,850 Hz)
Harsh high-frequency harmonics above 15.5 kHz provoke autonomic sympathetic activation, ear fatigue, and sensory overload in neurodivergent listeners (Autism Spectrum / ADHD). We enforce an aggressive 8-pole brickwall lowpass filter that completely terminates ultrasonic harshness while preserving air and percussive transient crispness.
Microtonal Pythagorean Retuning (A = 432 Hz)
Standard equal temperament at 440.0 Hz creates psychoacoustic tension over multi-hour focus sessions. Kharivox applies a high-order sinc pitch-shift algorithm without temporal dilation, retuning reference pitch from 440 Hz to 432 Hz Pythagorean harmonic proportions to maximize continuous listener endurance.
Neural 4-Stem Separation (Demucs v4)
Synthesized audio cannot be mastered as a flattened stereo composite without compromise. Demucs v4 runs directly on the local RTX 4060 GPU (8GB VRAM) to separate drums, bass, leads, and noise beds into isolated 24-bit streams, permitting surgical equalization and independent stereo placement.
Crest Factor Smoothing & Zero Startle
Startle responses trigger the amygdala and abruptly terminate creative and technical flow states. Kharivox governs dynamic crest factor through gentle tape saturation and multi-band soft-knee limiting, ensuring that transient peaks never exceed baseline root-mean-square loudness by more than 8 dB.
Streaming Compliance (-14.0 LUFS / -1.0 dBTP)
Consumer streaming normalization algorithms penalize over-compressed audio with destructive gain attenuation. Our mastering chain locks masters precisely to -14.0 LUFS integrated loudness with a -1.0 dB True Peak brickwall ceiling, preventing inter-sample clipping during lossy AAC and Opus transcode.
