This suite of DirectX plugins cleans up audio from any source. Remove the clicks, crackle, hiss and hum from recordings.

The programs - DeClicker/DeCrackler, DeNoiser, Filter Toolbox, Stereo Processor and Band Extrapolation - are not standalone but intended for use in a DirectX-compatible audio program such as Sonar, Sound Forge, CoolEdit Pro or WaveLab.

DeClicker/DeCrackler will automatically remove clicks and crackles from recordings (with no corruption of the source material), while DeNoiser removes broadband noise (hisses or hums) using algorithms based on psycho-acoustic techniques.

Filter Toolbox is a set of digital filtering tools for low, high and band pass filtering with 32bit internal processing.

The final two tools, Stereo Processor and Band Extrapolation, provide the ability to create stereo from mono, and synthesise high and low frequency harmonics respectively.

Each tool supports 24 bits/96KHz.
