What these tools are for
When you record a vocal over a beat, the first questions are always the same: how fast is the beat, what key is it in, what chords are under it, and is my vocal clean and loud enough? These tools answer them in seconds so you can set your project tempo, your autotune scale and your levels before you start mixing.
They are the same kinds of checks Tunedzy runs automatically before it cleans, tunes and masters a rough vocal for you, and the app is free to try for 7 days.
Questions
Are these tools really free?
Yes. No sign-up, no limits and no watermarks. They are free forever.
Do you keep my audio?
No. Files are decoded and analysed by your own browser. Nothing is sent to our servers.
Why is it free?
These are the same kinds of checks Tunedzy runs before it fixes a vocal. If they are useful, the Windows app (also free) does the fixing for you.
Which browsers work?
Current Chrome, Edge, Firefox and Safari. Very old browsers may not support the audio features.
