🎵 TuneCritic AI

Your AI-Powered Mix Engineer. > Instant, professional audio analysis that bridges the gap between demo and commercially ready tracks.

📋 Overview

TuneCritic AI is an intelligent audio analysis platform designed for producers and mixing engineers. Open-source and used along with Gemini API, the application judges your music track. Unlike standard spectrum analyzers, TuneCritic uses Machine Learning to listen to your track, compare it against a dataset of Billboard Top 100 hits, and provide actionable, timestamped feedback.

It answers the ultimate question: "Is this track ready for Spotify, or does it need more work?"
