MIXAGENT DASHBOARD — 13-TRACK SESSION, GENRE: TRAP, GAIN STAGING + PAN + COMPRESSION ANALYSIS
Every mix starts the same way: gain staging 30+ tracks, setting rough panning, carving EQ to stop stems from fighting each other, applying basic compression to tame dynamics. This takes hours of tedious, mechanical work before you even get to the creative decisions that actually define a mix.
Engineers with 20 years of experience do this work on autopilot. But it's still time they're spending on science instead of art. And for home producers without that experience, this phase is where mixes die — buried under mud, harsh frequencies, and competing elements.
MixAgent analyzes your multitrack session and makes intelligent, genre-aware mixing decisions — gain staging, panning, EQ shaping, compression settings, frequency conflict resolution — then applies them directly to Pro Tools.
You stay in the driver's seat. Accept, reject, or modify any decision from the dashboard. MixAgent handles the first 80% in minutes so you can spend your time on the 20% that actually matters: the creative choices that make a mix yours.
MixAgent runs entirely on your machine. Your audio never touches the internet.
Export your Pro Tools tracks as individual audio files to any folder. WAV, AIFF, MP3, FLAC, OGG, M4A — MixAgent reads them all.
MixAgent's stem analyzer runs 22kHz downsampled spectral analysis with 500 FFT frames across a 15-20 second window. Per-stem output: RMS, peak, crest factor, LUFS, spectral centroid, bandwidth, rolloff, flatness, 7-band frequency energy, dynamic range, activity ratio, and transient score.
The gain staging engine classifies each track by role (kick, snare, bass, vocal, pad, lead, fx) from the filename, selects a genre profile (hip hop, pop, R&B, rock, country, EDM), and calculates targets with relational balance enforcement, activity-scaled adjustments, and intent detection for intentionally quiet tracks.
PTBridge sends 14-bit fader values and pan positions to Pro Tools via HUI protocol over virtual MIDI. Bank switching handles sessions of any size. Watch your faders move in real time.
Every stem gets a full spectral fingerprint: RMS and peak levels, integrated LUFS, crest factor (dynamic range indicator), spectral centroid and bandwidth (brightness and spread), spectral rolloff and flatness (tonal vs. noisy), 7-band frequency energy mapping (sub, low, low-mid, mid, high-mid, high, air), activity ratio (how much of the stem is active), and transient score (percussive vs. sustained). This isn't a simple loudness meter — MixAgent understands the sonic character of every track in your session.
Six built-in genre profiles — hip hop, pop, R&B, rock, country, and EDM — each with calibrated target levels and relational balance rules. In hip hop, kick sits 3-6 dB above bass. In rock, guitars and drums share the forefront. The engine classifies each track by role from its filename (kick, snare, bass, vocal, pad, lead, fx, etc.), then computes gain targets that maintain genre-appropriate balance while preserving -3 dB master headroom. Intentionally quiet tracks are detected and preserved. Sparse tracks aren't over-boosted. Every decision has a reason.
PTBridge communicates with Pro Tools through the industry-standard HUI protocol over virtual MIDI ports (loopMIDI). It sends 14-bit fader values for precise level control, pan positions via V-Pot encoders (with stereo track support for independent L/R panning), and handles automatic bank switching for sessions with more than 8 tracks. The connection uses standard ping/keep-alive messages to maintain the HUI handshake. Run in --slow mode and watch your faders move one at a time — perfect for demo videos.
MixAgent generates custom FabFilter plugin presets (.ffp files) calibrated to your specific stems. The preset library includes 54+ EQ presets for Pro-Q 3 covering high-pass filters at multiple frequencies, mud cuts (200-500 Hz), harshness reduction (2-5 kHz), presence boosts, air shelves, instrument-specific chains, and masking resolution curves. Additional presets for Pro-C 2 (LUFS-relative compression), Saturn 2 (role-based saturation), Pro-MB (multiband dynamics), Pro-L 2 (limiting), and Pro-DS (de-essing). Load the presets, trust the analysis, adjust to taste.
When two stems occupy the same frequency range — kick and bass fighting in the low end, vocal and guitar competing in the midrange, multiple synth layers stacking in the highs — MixAgent identifies the conflicts from the spectral analysis and generates corrective EQ recommendations. In future versions, these corrections apply automatically through the FabFilter preset system. The AI doesn't just tell you there's a problem; it tells you exactly where (frequency), how much (dB), and which track should yield.
Built specifically for Windows Pro Tools users — the underserved majority in a market dominated by macOS-focused tools. Every computation runs on your local CPU. No cloud processing, no audio upload, no subscription to someone else's server farm. Your unreleased sessions stay on your machine. Python 3 with librosa, numpy, scipy, mido, and soundfile. No GPU required for the analysis tier.
MixAgent is built as a modular three-layer system, designed to scale from basic offline analysis to real-time AI-powered mixing.
Python-based DAW control via HUI/MIDI protocol (python-rtmidi + loopMIDI virtual ports) and Windows UI Automation (pywinauto for setup tasks). Handles fader control, pan, transport, and bank switching. This is the live connection between MixAgent's brain and Pro Tools' hands.
Custom C++/JUCE plugin suite for real-time audio analysis and processing — MA Monitor (transparent analysis tap), MA Parametric EQ, MA Compressor, MA De-esser, MA Gate, MA Saturator. These plugins replace the need for offline stem bouncing by feeding live spectral data to the AI engine. Pending Avid AAX developer approval.
Python analysis engine using librosa for spectral analysis, rule-based decision making for V1, PyTorch ML models trained on professional mix archives for V2, and Claude API natural language interface for V3. The intelligence layer that turns raw audio data into mixing decisions.
Other tools operate at the plugin level or require cloud uploads. MixAgent sees and controls your entire session.

MixAgent is built by Asaf Fulks, founder of The OC Recording Company. With over two decades of professional audio experience — credits on Netflix, ESPN, MTV, and Disney; records with Grammy-winning and platinum-selling artists including work with Lil Wayne and Kendrick Lamar; three #1 hits mixed for Common Kings (written by Meghan Trainor); and a Billboard-charting Christian Rock track for Whosoever South — MixAgent isn't built from theory. It's built from thousands of real sessions.
Named 2016 Producer of the Year by Now Hip Hop Magazine, Asaf holds a U.S. patent for microphone technology and a B.A. in Computer Science from Denison University. He is a member of the California State Bar, giving MixAgent the rare combination of deep technical audio knowledge, real software engineering skills, and professional business judgment.
Every gain staging target, every EQ curve, every genre profile in MixAgent comes from actual professional practice — not academic datasets or synthetic training data. This is what happens when a working engineer builds the tool he always wished existed.
