KlyveroSpeaker Test
Listen to speaker output and channel identification.
Set your device volume low before starting. Avoid testing uncomfortable frequencies or loud levels. Each tone stops after five seconds. This does not assess hearing or measure sound pressure.
Ready · use a low device volume
Current selection: stereo. Stereo requires suitable stereo output and operating system routing.
Cannot detect audible sound, physical channel wiring or hearing ability automatically
How to use this test
- Lower system volume, then play short left/right channel checks and report what you heard.
- Start a short tone or left/right channel check. Increase volume only if comfortable.
- Stop playback and record your own listening observation.
Checks included in this tool
Headphone Test
Listen to headphone channels and output clarity. This is a manual channel/listening check. It does not detect plugged-in headphones or certify acoustic response.
- Use your headphones at a low comfortable volume and compare left, right and stereo playback.
- Start a short tone or left/right channel check. Increase volume only if comfortable.
- Stop playback and record your own listening observation.
User must select physical output; no reliable automatic headphone detection or hearing diagnosis
Frequency/Tone Test
Listen to controlled frequency and bass/treble tones. Perceived loudness varies with frequency, output and hearing. This is not a hearing test or calibrated frequency-response measurement.
- Choose a conservative frequency and gain before starting a short tone.
- Start a short tone or left/right channel check. Increase volume only if comfortable.
- Stop playback and record your own listening observation.
Low initial volume, explicit start/stop; transducers/volume/listener affect perception; no hearing/medical test
How it works & what results mean
How the test works
Listen to speaker output and channel identification. It uses Web Audio; HTMLMediaElement. The workspace shows observations from this browser or asks for your own confirmation.
Understanding your result
The browser can generate channels but cannot know where sound physically emerged. OS routing and downmixing affect playback. Cannot detect audible sound, physical channel wiring or hearing ability automatically Missing data, blocked permission and an operation that could not run are shown separately. None establishes a hardware fault.
