Acon Digital Media has released version 1.5 of the Studio Clean collection of DirectX and, new in v1.5, VST compatible, noise reduction and quality enhancement plug-ins.

Studio Clean includes:

• 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 artifacts.
• StudioDeclicker contains two different algorithms. The actual click filter eliminates larger clicks and pops in the recording, while the crackle filter eliminates very frequent, but short clicks.
• StudioDeclipper restores recordings that suffer from analog or digital clipping.
• StudioRebirth adds synthesized high frequency harmonics to give life to old and dull sounding recordings.

Studio Clean costs $69; a demo version is available.
