Doubler

Doubler by Waves is a vocal doubling effect built for producers who want bigger, wider, more captivating mixes. It layers up to four independent delayed voices—each with its own delay time up to 100 ms, feedback, pitch modulation, detune of ±100 cents, and stereo panning—so you can thicken lead vocals, enrich background harmonies, or spread a mono instrument across the stereo field. A one-octave-down switch and output filtering add depth and tonal shaping, while the graphic display lets you drag gain and pan quickly. Because it can stack doubling in multiple layers, it excels at lush acoustic guitars, subtle width on synths, and creative sound design. With over 50 artist and factory presets, it suits hobby producers and mixers working in FL Studio, Ableton, or Logic who want a fast, musical way to add space and character to vocals and instruments.
