STEREO & FREQUENCY DIAGNOSTIC

Hear every part of your speakers.

Locate each channel, explore the full range and reveal buzzes, rattles or missing frequencies.

ADVANCED SIGNALS

Find problems a single tone can miss.

Generated locally · no audio file
Buzzing or rattling?

Replay the sustained bass and rattle finder. A physical vibration at repeatable frequencies can indicate a loose part or damaged driver.

One side sounds weaker?

Use the same tone and level on left, then right. Check balance settings and cable connections before assuming hardware damage.

A frequency disappears?

Small speakers naturally miss deep bass, while high-frequency hearing varies. Sudden gaps in the sweep are more useful than absolute loudness.

YOUR LISTENING RESULT

Record what you heard.

Compare at a comfortable volume. Mark a problem only when it repeats with the same signal.

Left and right are equally clear
