Vocal range test
What the vocal range test shows
A useful vocal range check is more than one strained high note. Oniki Check visualizes your measured low and high notes so singers can choose keys, plan practice, and track changes over time.
Lowest and highest notes
Detected notes are highlighted on a piano range so your vocal range is easy to understand at a glance.
Designed for safe testing
Use the tool to find a comfortable current range, not to force your voice past its limits.

FAQ
Common questions
How accurate is this vocal range test?
In a quiet room with a stable microphone, it is useful for note and range estimates. Voice type still depends on tessitura and tone, not only extremes.
Is my recording saved?
No. Audio is processed locally in your browser and is not uploaded to a server.
Can I use it without reading sheet music?
Yes. Results use note names such as C4 and A3, and the guide explains how to read them.
