DIRECTX NOISE REDUCTION FEATURES

The Sonic Foundry Noise Reduction DirectX Plug-In analyzes and reduces low-level background noise such as tape hiss, electrical hum, and machinery rumble from recordings with minimal effect on the source material.
Audio is separated into its frequency components to distinguish distracting noise from the desired signal. The Noise Reduction DirectX Plug-In also includes Click Removal and Vinyl Restoration Tools. Click Removal enables click and pop removal automatically or manually for greater control. The Vinyl Restoration Tool reduces clicks and pops along with surface noise in a single pass.
