CarSound Doctor — AI Engine Acoustic Diagnostics

Overview: CarSound Doctor is an AI-powered automotive acoustic diagnostic platform designed for vehicle owners, fleet operators, mechanics, and small automotive workshops. By analyzing the harmonic frequencies of engine audio recordings using Gemini 2.0 Flash, OpenAI Whisper, and GPT-4o, CarSound Doctor identifies mechanical anomalies—including serpentine belt slippage, connecting rod knock, hydraulic lifter tick, exhaust manifold leaks, and alternator bearing wear—delivering structured repair triage and severity ratings in under 4 seconds.

The Problem: Vehicle owners lose an average of $400 annually due to late mechanical fault diagnosis, and over 60% of repair shops misdiagnose early-stage engine noises. Engine sounds contain critical vibration and acoustic telemetry that human ears cannot reliably decompose, leading to catastrophic engine block perforations and unexpected breakdowns.

The Solution: CarSound Doctor turns any smartphone into an intelligent mechanical stethoscope. Drivers hold their phone near the engine bay for 5 seconds. The acoustic engine decomposes combustion harmonics, rhythm periodicity, and friction squeal, returning a clear severity rating (Low, Medium, High), confidence score, 3 actionable repair steps, and predictive maintenance timelines.

Key Capabilities: 5-second live microphone capture with live frequency visualizer; Multi-modal audio and photo ingestion; Instant mechanical fault classification; REQ-007 compliant predictive maintenance disclaimer; Sensifai Gatekeeper metered billing at $0.05/scan; Privacy-preserving 24-hour raw audio data purge.
