RTA·01 Real-Time Spectrum Analyzer — Room / EQ Calibration
STANDBY

Uses your microphone as input. For room correction, place a measurement mic (or reasonably flat USB mic) at the listening position. Grant microphone access when prompted — audio is processed locally in your browser and never leaves your machine.

TONE GEN
Hz
Start at low volume. Sweeps and pure tones can be much louder-sounding at some frequencies than others.
CAPTURING… 0.0s
No target curve set yet. Go to the ANALYZER tab, get a good live reading (ideally with a pink-noise sweep playing), then come back here and click CAPTURE AS TARGET. Once captured, this becomes your reference — take your mic to another room/speaker, capture a new live reading, and this tab will show you exactly which 31-band EQ sliders to move to match your saved target.
