V2.1.0 — The Clean Paradigm
CRISP MASTER PRO
Find the music. The rest is the artifact.
A standalone Windows audio restoration and mastering tool. A new Clean paradigm locates the musical content in your track — harmonics, sinusoids, transients, formants — and subtracts the non-musical residue. What remains is your music without the damage. Clean regions stay untouched. Damaged regions get only what they need.
No AI models. No pre-trained networks. No cloud. No subscription. Deterministic physics-based DSP, all core algorithms written from scratch. Your audio never leaves your computer.

HOW IT WORKS
STEP 01
Music Detector
Finds the musical content in your track — harmonics, sinusoids, transients, formants. Everything that belongs.
STEP 02
Difference Analyzer
Iteratively refines the non-musical residue. Artifact-free overlap-add processing. No low-frequency pumping.
STEP 03
Clean Output
Clean = Input minus residue. Nothing added, nothing hallucinated. What you hear is what was always there.

WHAT'S IN V2.1
Reference-Match
Transfer tonal character from any reference track. SUB REF ONLY matches sub-bass (20–45 Hz) for SPL-style low-end. FULL AUTO REF transfers the full 24-band spectral tilt. Blend 0–100%. Loudness is never changed by the reference — only tonal character.
A/B/C Live Playback
Switch between INPUT, DIFF, and CLEAN during playback without interruption. DIFF shows exactly what the engine removed — your built-in sanity check. What you hear is byte-identical to what you export.
Live FX Panel
Bass, Mids, Highs, Width — live during playback. Off-thread processing, no slider lag. Byte-identical between live preview and export.
Batch Processing
Add files, add folders, or drag and drop. Output to target folder or in-place with _CRISP suffix. Collision handling automatic. ABORT finishes the current file cleanly — no partial output.
Live Meters
VU (instantaneous RMS, both channels), LUFS (400 ms integrated), True Peak (4x oversampled, BS.1770-4 compliant). All live during playback.
Three Vectorscopes
INPUT (purple), REMOVED (amber), OUTPUT (acid green). Lissajous stereo visualization synchronized to waveforms. See exactly what changed in the stereo field.
Time-Synced Waveforms
All three waveforms (input, diff, clean) with synchronized M:SS position and playback marker. Staged progress bar with stage name and gradient fill during processing.
Source-Aware Processing
Codec-aware source classifier. No false positives on 128 kbps MP3. Adapts processing to the actual degradation profile of your file.

YOUR AUDIO STAYS YOURS
No uploads, no cloud processing, no telemetry. The engine runs 100% locally on your machine. No internet connection is required for activation or operation. Your studio work stays your studio work.
