Record your car's sounds and get instant AI-powered diagnostics for mechanical issues.
Likely causes: Low octane fuel, carbon buildup, or incorrect ignition timing
Our AI analyzes sounds that human ears might miss, detecting issues before they become expensive problems.
Use your phone's microphone or connect an OBD-II mic to capture engine, gear, or suspension noises.
Our hybrid CNN-Transformer model analyzes spectrograms to detect patterns and temporal dependencies.
Receive a detailed diagnostic with likely issues, confidence scores, and repair recommendations.
Our advanced NVH optimization ensures accurate sound capture even with phone microphones.
(sample rate ≥44.1kHz)
Filters out ambient sounds like wind and traffic
Helps you record near problem zones (engine bay, wheel wells)
For enhanced vibration analysis
Hold to record. Release to analyze.
Our model combines the best of convolutional and transformer networks for unparalleled diagnostic accuracy.
Our model combines the best of convolutional and transformer networks for unparalleled diagnostic accuracy across different vehicle makes and models.
Identifies characteristic sound signatures like piston slap (2-5kHz) or belt squeal (1-3kHz) with spatial awareness.
Analyzes how sounds evolve over time to detect intermittent issues like valve train problems or transmission slippage.
Partnered with professional mechanics to collect labeled sounds for 150+ common issues across 30+ vehicle manufacturers.

Stop guessing what that noise is. Let Ascend Acoustics analyze it with professional-grade AI.
Our AI achieves 94% accuracy in controlled tests with known issues. Real-world accuracy depends on recording quality but typically exceeds 85% for common mechanical issues. For best results, record in a quiet environment near the suspected problem area.
Ascend Acoustics specializes in diagnosing mechanical issues through sound and vibration analysis. This includes engine problems (knocking, misfires), transmission issues, wheel bearing wear, suspension problems, belt and pulley issues, exhaust leaks, and more. Electrical or computer-related issues typically require OBD-II diagnostics.
No special equipment is required - your smartphone's microphone works for most diagnostics. For optimal results, we recommend using an external microphone placed near the suspected problem area. Professional mechanics can connect OBD-II devices for enhanced diagnostics that combine sound analysis with vehicle computer data.
Ascend Acoustics complements but doesn't replace professional mechanics. Our AI excels at initial diagnosis and can detect subtle sounds humans might miss. However, a mechanic's hands-on inspection is still needed for confirmation and repair. Think of Ascend Acoustics as giving you expert-level information before visiting a shop.
