Reduce your volume, especially when using headphones.

Low digital gain does not guarantee safe acoustic volume. Stop if uncomfortable; do not raise volume to hear inaudible tones.

FrequencySweepPhase

Driver matching plays the same sweep in left and right. Perceived imbalance can come from drivers, fit, the room or hearing. Phase is a subjective stereo wiring check; DSP and mono playback can change it.

Tones last 1 second; sweeps 6 seconds. Auto L/R uses one tone per channel; matching uses identical 6-second sweeps. Sound never resumes automatically after hiding the tab.
