Studio Clean is a audio plug-in suite. Studio Clean is a DirectX and VST compatible plug-in suite for use in host applications such as audio editing or processing software. It consists of four plug-ins for noise reduction and audio restoration:
1. StudioDenoiser is a plug-in for broadband noise reduction. Because the algorithm takes the perceptual properties of the human hearing into account it achieves a high level of noise reduction with a minimum of audiable artifacts.
2. StudioDeclicker contains two different algorithms. The actual declicker algorithm eliminates larger clicks and pops in the recording, while the decrackler algorithm eliminates very frequent, but short clicks.
3. StudioDeclipper restores recordings that suffer from analog or digital clipping.
4. StudioRebirth adds synthesized high frequency harmonics to give life to old and dull sounding recordings.

Studio Clean Features:
1. Accessible from DirectX or VST compatible host applications
2. Supports multichannel formats up to 8 channels, including 5.1 and 7.1 surround formats
