Avoid placing compressors, EQs, or time-based effects (reverb/delay) before the tuner, as these can confuse the pitch detection algorithm.

If you don’t know the key, you can use the Waves Key Detector plugin or external sites like Tunebat to find the song's BPM and key.

Select the root note (e.g., C) and the scale type (e.g., Major or Natural Minor).

For the most accurate pitch detection, Waves Tune Real-Time should be the on your vocal track.
