Scaled.
Always in key.
Detects the musical scale and tuning of any audio — quietly, accurately, and in real time.
What Scaled does
Scaled passively analyzes the key of your music (e.g. C# minor) and the precise tuning of A (e.g. A = 437.2 Hz), so you always know what you’re working with.
The only free tool of its kind
While other options are paid, web-based, or imprecise, Scaled is fully offline, real-time, and designed for creative flow.
Scaled
The only free plugin that shows both the musical key and exact pitch of A — in real time.
Whether you're sampling, singing, or syncing instruments, Scaled quietly keeps you in key.
Designed for clarity and flow.
Available as VST3 and AU on Mac and Windows.
