Alexander Pedals Velvet Noise Stereo Widener

Most stereo wideners fake it. They shift phase, add delays, or manipulate frequency bands in ways that can fall apart on headphones, in mono, or at the mastering stage.

Velvet Noise takes a different approach, using a method grounded in acoustic research into how the human brain actually perceives space.

At its core is a technique called velvet-noise decorrelation. Rather than treating the left and right channels as a single stereo image to stretch, Velvet Noise makes the two channels genuinely less similar to each other in a way that mirrors how real acoustic spaces naturally scatter sound.

The result is a wider, more spacious stereo image that holds together in mono, survives the mix, and keeps the center intact.

Simple Control, Natural Width

A single knob controls the amount of widening:

• Fully counterclockwise: Your original signal, completely untouched.
• Turn clockwise: Progressively blends in the widened signal.
• Maximum settings: Adds subtle modulation for more extreme stereo separation.

No phase weirdness, no pumping, and minimal latency — just a natural, spacious stereo field that stays usable in a real mix.
