Keep your tonal curve in the zone

Not just a meter.

Most tonal analysis tools stop at showing you the problem. Tone Zone goes further — it analyzes, corrects, and lets you fine-tune by hand, all in the same window without switching plugins.

Traditional Approach

Open a metering plugin to see your tonal curve. Spot the issues. Switch to a separate EQ to make corrections. Flip back to the meter to check your work. Repeat until it looks right — or until you run out of patience.

See the problem in one plugin, fix it in another.

The Orra Way

See your tonal curve against a genre target. Turn up the correction knob and the FFT-based EQ nudges your spectrum toward the target automatically. Then fine-tune with a 6-band parametric EQ and add per-band saturation — all in the same window, all updating in real time.

Analyze, correct, and sculpt without ever switching plugins.
