FASoft ParEQ is a DirectX plug-in that lets users equalize mono and stereo wave files tracks from within audio applications that support the DirectX plug-in architecture. You can modify the sound of a wave file boosting selected bands of frequencies, eliminating others, creating in this way new sounds or enhancing the quality of bad recordings, such as those made through a non-excellent microphone. Using separate settings for left and right channels, the plug-in can "spatialize" the sound. The settings can be easily adjusted with the mouse using an interactive frequency response window. It supports both 16 bit and 24 bit processing, and uses internal 64 bit precision for optimum sound quality and performance. It can be used from inside many audio applications.
