GRM Tools Spectral Transform (ST) is a bundle of four plug-ins that provides extremely powerful tools to transform deeply the spectral content of your audio material.
Conceived and realized by the Groupe de Recherches Musicales (Musical Research Group) of the National Audiovisual Institute, Paris, France, GRM Tools is the result of numerous years of research and development by composers and sound designers in sound transformation software.
Contrast adds vibrancy, liveliness, depth, and subtle changes in timbre to sounds in mastering applications. As one user said, It makes my old tapes come alive again. Better than when they were originally recorded. Contrast can also be used to create a wide range of extreme transformations and effects.
Equalize gives you powerful and dynamic controls to rebalance the highs, lows, and midrange of a sound. In the stereo version of this plug-in, you can control the equalization curves of left and right channels independently or together.
Shift is used to transpose or transform a sound by any combination of frequency scaling or frequency shifting.
Warp is used to transform a sound by rearranging its frequency components in a completely free and creative way. One user said, This is the most far out, the most radical, the most bizarre, powerful, and effective sound transformation tool I have ever seen.
