Deterministic Audio Analysis.
Every deviation explained.
Mathematical deviations from ITU / EBU / AES standards only.
No inference. No estimation. No black boxes.
K-weighting applied to raw PCM stream. Integrated loudness via gating algorithm.
Welch-method PSD across 32 bands. Cosine similarity clash matrix. ±0.1 dB precision.
Composite score S=Σ(wk·mk). Priority actions ranked by severity. Zero inference.
8-Module Technical Schematic
Deterministic, bit-perfect analysis. Every module outputs an explicit dBFS deviation against an open measurement standard. No inference. No estimation.
Frequency Masking

Cosine-similarity clash matrix between spectral vectors. Identifies destructive interference in the Kick/Bass relationship.
32-Band Spectral Audit
Welch-method power spectral density across 32 critical bands. Pinpoints humps, holes, and resonances with ±0.1dB precision.
Stereo & Mono Compliance
6-band L/R correlation profiling. Verifies translation from club PA systems to mono mobile devices.
Master Bus Analytics
Crest factor differential between drum transients and mix ceiling. Detects bus crush with sub-millisecond precision.
Mix Readiness Index
Composite 0–100 score from four deterministic pillars: Loudness 40%, Spectral 25%, Dynamics 20%, Stereo 15%.
Priority Action Engine
Categorical deviation list sorted into CRITICAL / WARNING / INFO tiers. Every flag tied to a specific dBFS threshold.
Genre Benchmarking
Z-score comparison against mathematical fingerprints of 172 successful commercial releases across 15 genres.
A/B Version Tracking
Quantitative delta overlay between current and previous iterations. Tracks regression and improvement per metric.
Formula Verification
Every metric emitted by the analysis engine is deterministic and verifiable against open measurement protocols. No proprietary black-box scoring.
Loudness & True Peak
The global standard for broadcast and streaming normalization.
Integrated Program Loudness
Standardized measurement of perceived loudness and loudness range (LRA).
Inter-Sample Peak Accuracy
Precision peak detection using Whittaker-Shannon interpolation protocols.
Your Music. Your Privacy.
MixAudit does not rely on generative AI or model training. Your music is analyzed using deterministic audio methods — not fed into training pipelines, not reused, not stored for learning. You stay in control.
MixAudit is built on transparent, deterministic analysis.
Here’s exactly how we handle your audio:
No Model Training
Your audio is never used to train machine learning models. We don’t build datasets from your work.
No Long-Term Storage
Files are analyzed in-session and automatically purged. We don’t keep your stems or mixes on our servers.
No Generative AI
MixAudit uses deterministic signal analysis — math, not neural networks. Every result is explainable and reproducible.
You Keep Full Ownership
We never claim rights to your uploads. Your intellectual property remains yours.
Pure Signal vs. Generative AI
A deterministic engine is not an opinion. Every output is a mathematical measurement against an open standard. Generative AI cannot make that claim.
Improve Every Mix
Less than the cost of a plugin. Better feedback than guesswork.
