The CX1V is a professional compressor/expander available as a VST plug-in for PC.

This unit offers an easy to use interface that drives a sophisticated and flexible dynamic control algorithm. The wide number of control parameters and features (e.g. look ahead, hard/soft knee), makes the CX1V the tool of choice to control the dynamic of vocal parts, instruments or complex mixes. Additionally, the expansion capability of the CX1V can be used to improve old audio recordings by restoring a more natural dynamic and an enhanced signal-to-noise ratio.

The CX1V compressor/expander has been designed to obtain an extremely transparent action with a natural and smooth response.

Professionals say:

"...ANWIDA delivers what it promises...The sound is consistently transparent, and the signal dynamic range compresses smoothly even at extreme settings. In our tests, for example, we found that the CX1V is effective in softening transients, such as from drum kits, without adding any coloration. Sometimes the transparency was so effective overall that we often checked to make sure the compressor was active...Since most musicians are usually concerned with compression rather than expansion of dynamic range, it is easy to forget that the CX1V is also an expander. However, the expansion capability worked just as well and displayed the same virtues of transparency and smoothness...In addition, the demand on CPU usage is very low, which means that on most computers there should be little problem running as many instances of the CX1V as needed for multi-track recording. In general, this uncomplicated, straightforward compressor/expander is a reliable workhorse. It does the job it's supposed to do, and it does it very well."

"What's most impressive about the CX1V is the transparency. This is not a compressor that encourages "squashing"-type special effects, but you can easily restrict the dynamic range of everything from individual instruments to program material while retaining a very natural sound...if you crave a quality compressor, check out the demo of this fine plug-in."

"The GUI is very nice and the sound is excellent!!!! Both Limiter and Compressor have really good algorithms!!!!! I tried lots of compressors within the last 3 months, only the ones from Waves comes near to yours. Very good work!!!!!"

"I'm really impressed by the transparency this compressor has. With this plugin it's so easy to compress; unnoticeable, very good.
Nice looking and easy to use interface. Great compressor!"
