Features & Capabilities

Engine Sound Analyzer: RPM Calc is a Chrome extension that estimates engine revolutions per minute (RPM) by analyzing the exhaust noise of motorcycles and cars while idling. Perfect for vehicle maintenance when a tachometer is not available, such as with scooters or older vehicles.

The tool uses the microphone to capture engine sound, splitting it into frequency components and calculating RPM based on the loudest frequencies. Users can configure engine parameters like the number of strokes and cylinders, adjust gain and thresholds for accuracy, and start or stop measurements easily. Although results may vary depending on ambient noise, vehicle type, and microphone quality, it provides a handy reference for DIY enthusiasts and professionals alike.

With safety reminders and user-friendly features, this extension helps you maintain your engine's idle performance more precisely without expensive tools. Whether tuning carburetors or ensuring proper idle speed, Engine Sound Analyzer aids your vehicle upkeep with sound science and convenience.

User Reviews

Users find the Engine Sound Analyzer app very useful and accurate for multi-cylinder 4 stroke engines, praising its minimal interface and precision close to real tachometers. However, many report significant inaccuracies with single-cylinder 2 stroke engines, often showing unrealistic RPM values. Several users noted issues with adjustments not impacting readings, problems reinstalling after phone updates, and slow ad loading causing suspicion. Overall, the app is effective for certain engine types but has notable limitations and usability concerns for others.

Pros

Accurate and helpful for multi-cylinder 4 stroke engines, with readings close to dash tachometers and OBD2 scanners.
Allows tuning the filters and thresholds to improve speed detection accuracy.
Minimal and user-friendly interface for easy operation.
Useful for adjusting and checking idle speed on various engines, including scooters and outboard motors.

Cons

Inaccurate readings for single-cylinder 2 stroke engines, often showing unrealistic RPM values.
Adjustments and settings sometimes do not affect the readings, leading to frustrations.
App removal or uninstallation issues reported after phone updates, with difficulty reinstalling.
Advertisements are slow to load, raising concerns about the app's safety or behavior.
Lack of a clear exit option within the app.

Why time out..? Is it free or paid...?

Seems to work as intended. I wanted to check and adjust the idle speed on my Buddy 50 2 stroke scooter. I thought it sounded a bit high. It was. Lowered to 1900 +-200
