What This Page Covers
This page covers microphone failures, missing detections, false C7 jumps, and results that change too much. For the normal guided flow, start with How to Use the Vocal Range Test.
Microphone Permission Does Not Work
- Open the site settings near the address bar and make sure microphone access is allowed.
- If you denied access earlier, change it to allow and reload the page.
- Close recording or call apps that may already be using the microphone.
- Confirm you are using the HTTPS version of
oniki-check.com. - Try the latest Chrome, Edge, Safari, or Firefox.
Audio is processed in the browser and is not sent to the server as a recording.
Notes Are Not Detected
- Keep the microphone 20 to 30 cm away and avoid covering a phone microphone.
- Hold an “ah” near the same pitch for at least 1.2 seconds.
- Avoid breath-only sounds, heavy vibrato, and very quiet input.
- Use headphones if the speaker is feeding back into the microphone.
The Timeline Jumps Near C7
Pitch detection can catch harmonics, breath, or room noise instead of the vocal fundamental. If the line repeatedly jumps near C7:
- Turn off music, television, and steady room noise.
- Move back from the microphone and avoid blowing directly into it.
- Start near speaking volume instead of shouting.
- Use “Repeatable chest range,” not “Detected extreme,” as the result.
Results Change Between Tests
Keep warmup, sleep, room, device, and microphone distance as consistent as possible. Test two or three times and use the notes that repeat across sessions instead of a one-off extreme.
Track chest voice and falsetto separately. See the Japanese karaoke pitch notation chart if you need to translate C3 or A4 into mid1C or hiA.
When to Stop
Stop the test if you feel pain, hoarseness, throat pressure, or shortness of breath. A vocal range test should help you understand your current range, not push past it.
