Audio Compass
A free 3D spatial audio compass for blind and visually impaired users. Uses HRTF-based Web Audio to position directional sound beacons around you. Adjustable volume, pitch, tone type, haptic feedback, and target bearing mode.
Navigate by listening to directional sound beacons
Features
How to Use the Audio Compass
Open this page on a mobile device with orientation sensor (phone or tablet).
Grant orientation sensor permission when prompted.
Tap "Start" to activate spatial audio beacons — North is a high ping, South a low hum, East clicks, West a bell.
Adjust volume with the slider. Change pitch and tone type to find sounds that work best for you.
Enable voice announcements to hear your heading spoken aloud. Choose interval or continuous mode.
Turn on vibration for haptic feedback when you cross cardinal directions.
Use Target mode: enter a bearing (0-359), tap Set, and follow the audio/visual guide to reach it.
Frequently Asked Questions
Does the audio compass work on desktop?
The audio compass requires a device with an orientation sensor (accelerometer/gyroscope), which is typically found only in phones and tablets. Desktop computers do not have this sensor.
How accurate is the compass?
Accuracy depends on your device sensor quality. Most modern smartphones provide heading accuracy within 5-10 degrees. Use the Calibrate button to improve relative accuracy.
What are the different sounds for each direction?
North uses a high-pitched ping (880 Hz), South a low hum (220 Hz), East a click pattern (660 Hz), and West a bell tone (523 Hz). You can change all tones with the pitch slider and tone type selector.
How does the target bearing mode work?
Enter a compass bearing (0-359), tap Set, and a green marker appears on the compass. The tool shows how many degrees you need to turn and announces when you reach the target (within 5 degrees). You also get a vibration pulse on arrival.
Is this accessible for blind users?
Yes, the tool is designed primarily for blind and visually impaired users. It uses 3D spatial audio (HRTF), voice announcements with 16-point compass directions, haptic vibration feedback, and high contrast mode. All controls have ARIA labels for screen readers.
Can I change how the compass sounds?
Yes. Use the volume slider (0-100%), the pitch slider (0.25x to 4x frequency), and the tone type buttons (sine, square, triangle, sawtooth) to customize the sound to your preference.
