Left and right stereo test
Check whether sound plays through the left channel, right channel or both.
Use a moderate volume. The test checks signal playback; it does not measure acoustic quality or certify hardware condition.
Left and right stereo test
This tool lets you check left and right channels. It is useful for spotting differences, anomalies or behaviour that may need a more specific audio test.
How it works
The test plays or analyses an audio signal and shows the result immediately. Behaviour can vary with the device, browser, speakers, headphones and audio processing.
What you can check
- La prueba reproduce o analiza una señal de audio y muestra el resultado de forma inmediata. El comportamiento puede variar según el dispositivo, el navegador, los altavoces, los auriculares y el procesamiento de audio.
How to perform the test correctly
- Abre la herramienta y selecciona la prueba que quieras realizar.
- Desconecta dispositivos que puedan desviar el audio si quieres probar la salida integrada.
- Utiliza un volumen cómodo.
- Repite la prueba si detectas un resultado extraño.
- Si el síntoma persiste, utiliza una herramienta relacionada para aislarlo mejor.
How to interpret the result
The result is indicative and should be considered together with other checks. A different response can be caused by the device, its settings or playback limitations and does not by itself confirm physical damage.
