Acon Digital Media has released Studio Clean, a collection of DirectX plug-ins designed for noise reduction and quality enhancements.

Studio Clean consists of the following plug-ins:

• 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 algorithm eliminates larger clicks and pops in the recording, while the crackle filter algorithm 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.

The plug-ins support multi-channel audio up to eight channels, including 5.1 and 7.1 surround formats. Both PCM formats (up to 32 bit resolution) and floating point (IEEE 32 bit) formats are supported.

Studio Clean costs US$69 and a demo version is available.
