Test 01
Audio test
Confirm that your browser and output path can play a known reference.
A browser signal-path lab
Start with a known signal.
Use a clear reference, change one thing at a time, and keep a record of what the problem followed.
Test index
Start with the path you have.
Open test
Test 02
Tone generator
Generate a controlled reference tone with explicit level and safety limits.
Test 03
Left / right test
Check channel routing before moving into fault isolation.
Test 04
Speaker test
Run a short, repeatable speaker check and record what you hear.
Test 05
Headphone test
Check both sides and turn a failed result into a controlled next experiment.
Test 06
Frequency sweep
Run a controlled sweep and record repeatable changes across the range.
Test 07
Noise generator
Generate deterministic white, pink or brown noise locally.
Test 08
Microphone test
Inspect digital level, waveform, spectrum, clipping and actual browser settings.
The practice
Move from symptom to evidence.
Map the path
Name the device, connection and app in play.
Run one reference
Use a known test before changing the setup.
Change one variable
Let the result show where the fault followed.
A useful audio test
Does more than say pass or fail.
States the reference
You know exactly what the browser was asked to do.
Names the uncertainty
A browser level is not a calibrated room measurement.
Keeps the next step clear
Your notes survive the handoff to support or a technician.
