Speaker testing is essential for verifying audio equipment functionality, troubleshooting sound issues, and ensuring optimal audio quality. This free online tool generates pure sine wave tones that help identify problems with individual speakers, stereo balance, or frequency response.
The left/right speaker test helps identify if one channel isn't working, which could indicate a wiring issue, a damaged speaker, or incorrect audio settings. The frequency tests help check if your speakers can reproduce the full range of audible sound, from deep bass (100Hz) to high treble (8000Hz).
Use this tool to test any audio output device including desktop computer speakers, laptop speakers, external monitors with built-in speakers, headphones, earbuds, Bluetooth speakers, and home theater systems. For best results, test in a quiet environment and compare both channels carefully.
