Everything inside MixEngine AI

A complete AI-powered mixing assistant that runs entirely on your machine. No cloud dependency, total privacy, professional results.

Real-Time Analysis

6 analyzers running in real-time

Every instance of MixEngine AI continuously analyzes the audio on its track and reports data to the local server for global mix context.

  • FFT Spectrum Analyzer — 4096-point FFT, 32 logarithmic bands (20Hz-20kHz), updated every 100ms. Compared against genre target curves.
  • Level Metering — Peak, RMS, and crest factor per channel. True peak detection with 4x oversampling.
  • LUFS Loudness — ITU-R BS.1770 compliant. Momentary (400ms), short-term (3s), and integrated loudness. Per-track and mix bus.
  • Spectral Analysis — Spectral centroid, spectral rolloff, and spectral flux for tonal balance and brightness tracking.
  • Stereo Image — Cross-correlation coefficient (-1 to +1), stereo width estimation, and phase coherence monitoring.
  • Transient Detection — Attack sharpness, sustain level, and dynamic range. Feeds into compression and gate recommendations.

AI Architecture

Local AI, zero cloud dependency

All AI runs on your machine. The plugin communicates with a local Python/FastAPI server via WebSocket, which in turn talks to Ollama for LLM inference.

LLM Function Calling

The AI doesn't just chat — it calls structured tools to control your mix.

set_gain — Set track gain in dB
set_eq — Configure parametric EQ bands
set_compressor — Set threshold, ratio, attack, release, knee, makeup
set_pan — Set stereo position (-100 to +100)
set_send — Route to bus with level control
Effect Chain

Host your VST3 plugins

Each track instance can host VST3 plugins in series. Free: 2 slots. Pro: unlimited.

Wet/dry per slot, bypass toggle, drag-to-reorder, automatic latency compensation, plugin preset management.

Sidechain Compressor & Gate

Route any track as sidechain source. Ducking for kick/bass, gating for drums. Full control over threshold, ratio, attack, release, hold.

Mid/Side Processing

Split audio into mid and side components. Apply independent EQ and dynamics to each. Perfect for mastering and stereo enhancement.

Master Chain

Dedicated master bus with soft clipper (drive, ceiling, knee) and true peak limiter (threshold, release, lookahead). Essential for final loudness.

Automation

Record and playback parameter changes over time, synced with DAW transport. Linear, smooth, and step curves. Automation lanes per parameter.

Reference Track

Load a reference track and compare your mix in real-time. Level-matched A/B comparison with spectral overlay.

Mixing Techniques Library

A curated library of mixing techniques (NY compression, Haas effect, serial compression, etc.) that the AI can auto-apply to your tracks.

Plugin Scanner

Scans your system for installed VST3 plugins. Background thread, crash isolation, categorization by type.

Processing Tools PRO

AI-powered audio processing

Four dedicated processing engines, all running locally.

Noise Reduction

RNNoise-based neural denoiser. Real-time, zero latency. Removes background noise while preserving voice clarity.

Source Separation

Demucs v4 for stem extraction: vocals, drums, bass, other. Offline processing with progress tracking.

Audio to MIDI

Basic Pitch (Spotify) for polyphonic audio-to-MIDI conversion. Drag & drop MIDI export to your DAW.

Auto Mastering

Matchering for automated mastering. Match your track's loudness and frequency profile to a reference.
