Find the key. Feel the frequency.
ROOTLAB is a key finder plugin that gives music producers a clear visual reference for a sound’s musical key and root frequency. Whether you are checking a sample, shaping a bass line, or exploring a vocal idea, ROOTLAB puts the information you need in two focused views.
KEY: Understand the musical key
The KEY view displays the detected key and its major or minor quality. A confidence percentage and alternative matches give you more context when the audio does not point to one obvious tonal center. Compare the possibilities before deciding how a sound fits your track.
HZ: Inspect the root frequency
The HZ view displays the root frequency in hertz alongside the corresponding note and cents deviation. Use it as a quick reference when checking the pitch area of a bass sound, sample, or vocal signal.
The waveform and piano keyboard make the analysis easy to follow. Sharp/flat notation, Freeze, and Reset controls keep the essentials close at hand.
BLACKRAM AUDIO ROOTLAB helps you see the key and frequency behind the sound.
