Find where your voice lands.
A song can be perfectly good and still feel wrong because it was written for somebody else’s voice. This tool finds where your voice naturally centers so you can move the song into a key that does not make the low notes disappear or the high notes turn into a fight.
What the key actually changes
Changing the key does not change the melody or the song. It moves every note up or down together. The point is to place the melody where your voice is strongest and most comfortable instead of forcing your voice to fit the original singer. The test listens to where you land, suggests a key, and gives you a practical place to start. You still try that key with the real song, because the highest, lowest, and longest notes are what decide whether it truly fits.

Troubleshooting
I hear no sound
Press Test sound. If the diagnostic says the audio system is running but you still hear nothing, check that the browser tab is not muted, the computer output is set to the correct speakers or headphones, and the system volume is up.
The microphone does not start
The page must be opened through HTTPS or localhost. Check the browser address bar for a blocked microphone icon, allow access, then reload the page. The diagnostic log will also report whether permission was denied or no input device was found.
The microphone starts and then seems to stop
Watch the live input-level bar in Diagnostics. If the bar still moves, the microphone is working and the detector is simply rejecting unclear pitch. Move closer, sing a steady vowel such as “ah,” and increase the sensitivity slider. If the bar freezes completely, another program may have taken control of the microphone.
The meter jumps between notes
Use headphones, reduce room noise, and sing one clean sustained vowel. Speaker bleed, vibrato, consonants, and breath noise can all confuse a pitch detector. The tool waits for a reasonably clear pitch before scoring a sample.
It misses quiet singing
Increase the microphone sensitivity slider. A setting around 2.5× is a good starting point. Laptop microphones may need 3× or 4×, while an audio interface may work better around 1× or 1.5×.
The melody is being detected as my voice
Use headphones. If you must use speakers, lower the volume and move the microphone farther from the speakers, since the reference melody and key tone can otherwise leak into the microphone on loud systems.
What this does not do
One test cannot define your permanent vocal range. Fatigue, warm-up, technique, and the melody itself can move the useful result.
What to do with the result
Try the suggested key with the actual song. The test gives you a starting point, not a law. A melody with one unusually high, low, or sustained note may need to move another step before the whole song sits correctly.
Find the song’s current key
Enter the chords from the song so you know where it starts before moving the entire progression to the suggested key.
Test the new key in time
Build the progression, loop it, and sing the real melody over it. That is where you find out whether the suggested key actually works.
