I Built an AI Audio Mastering Engineer with Claude — It Analyzes 13 Acoustic Measurements

What I Built MixMaster AI is an AI-powered audio mastering system. You upload a raw audio file, describe what you want in plain English, and Claude handles the entire mastering chain automatically. GitHub: https://github.com/Tanzil-Ahmed/mixmaster-ai The Problem Audio mastering requires deep technical knowledge — EQ curves, compression ratios, loudness targets, stereo imaging. Most musicians and indie creators can't afford a mastering engineer for every track. I built one with Claude. How It Works 1. Audio Analysis Claude analyzes 13 acoustic measurements from the uploaded file — loudness (LUFS), dynamic range, crest factor, spectral balance, stereo width, true peak, and more using librosa and pyloudnorm. 2. AI Decision Making (Claude tool_use) Claude reads the measurements + your creative brief and sets every DSP parameter — EQ frequencies and gains, compression ratio and threshold, saturation amount, stereo width, limiter ceiling. 3. Signal Processing Chain The full mastering chain r
