Questions

Is it really free?

Yes, on any website, personal or commercial. There is no account, no key and no limit. Please keep the credit line under the tool.

Is anything recorded or uploaded?

No. The vocal range and singing tests only measure pitch while someone sings, in their own browser. The song tools open the file on the visitor’s device; it is never uploaded.

Does it work on phones?

Yes, on iPhone, Android, tablets and computers, from about 320 pixels wide. The microphone tools ask the visitor for the microphone the first time.

Can I change the size?

Change the height in the code if your page needs it. The width follows your page up to 720 pixels.

Will it slow my page down?

The code includes loading="lazy", so the tool only loads when a visitor scrolls to it.
