A left right check tool is a simple audio utility that lets you test whether your headphones or speakers are outputting sound to the correct audio channels. It plays sound specifically to the left and right channels, helping users confirm the proper orientation of their audio setup.
How It Helps with Audio Channel Detection
It helps detect:
- Swapped or reversed channels
- Faulty headphones with no sound in one side
- Speaker wiring issues in stereo or surround systems
Difference Between Mono, Stereo, and Surround
- Mono: Single-channel audio (same sound in both ears).
- Stereo: Two-channel (left/right).
- Surround: Multi-channel, including rear and center.
How To Use
- Click "Start Test" and allow microphone access.
- Play audio into your mic
- Listen carefully—one sound should come from the left, then the right.
