Waves Doubler is a digital audio processor designed to replicate the effect of double-tracking. Unlike simple copying and pasting—which often leads to phase cancellation and a "hollow" center—Doubler uses small variations in pitch, timing, and panning to create a natural, lush stereo field.

By continuing to develop and refine the Doubler 2 Stereo technique, audio engineers and researchers can create more immersive and engaging audio experiences for a wide range of applications.

The Right Voice: He panned it hard right, detuning it up by 4 cents and adding a tiny 10-millisecond delay.

The Verdict: If you want a "shoegaze" guitar, use chorus. If you want a lead vocal to sound like it was sung by three people, use the Doubler 2 Stereo.
