Test tips

Make sure the audio output device is connected and selected.
Headphones are best for judging channel separation.
Keep the system volume moderate (around 30%) before starting.
Lower the volume before loud tests to protect your hearing.

Frequency response in detail

Frequency response describes how loud each band is. Listening to low (100Hz), mid (1kHz) and high (8kHz) in turn quickly reveals whether the three bands are balanced.

Reference points:

Low 100Hz: the bass foundation — checks depth and that bloated feel; overly loud points to a bass-heavy tune.

Mid 1kHz: the core of the human voice — checks mids are full and clear.

High 8kHz: treble detail — a dull or piercing high end both signal a problem.

Custom frequency: enter anything from 20–20000Hz to probe the response curve point by point.

Listening tips:

Lower the volume before testing high frequencies — they hit the ears hard.

Close your eyes and compare band loudness to spot obvious peaks and dips.

Subwoofer test: punch custom 20–80Hz tones to rattle the sub — listen for port chuffing or bottoming-out distortion.

Frequently asked questions

Why can’t I hear the low or high frequencies?

Human hearing spans roughly 20Hz–20kHz, but most ordinary speakers and budget earbuds can’t produce below about 60Hz, and high-frequency perception falls with age — this is normal.

How do I test bass depth?

Type 40, then 30, then 20 into the custom frequency. The point where you stop hearing it is your depth; lower-and-still-audible means better low-bass control.

How do I test treble reach?

Try 14000 and 16000. Keep the volume low — high tones are hard on the ears. If you can’t hear them, your hearing or the device’s top end has rolled off.

A custom frequency plays no sound?

Make sure the value is within 20–20000Hz, the page isn’t muted, and the system volume isn’t zero.
