Cube 2 from Virsyn
Here's what they say:-
"CUBE 2 is a musical instrument and the ultimate tool for sound designers who wish to have instant and intuitive access to all principal components every imaginable sound is build from. Every sound can be decomposed in a sine spectrum representing the harmonic and inharmonic partials and a residual noise spectrum for the noise components. The spatial character of a sound can be represented by a pan spectrum. The temporal evolution of these three spectra is a very convenient way to describe every sound. CUBE 2 is built around this model and allows you to manipulate the structure of a sound with all its components in a comfortable and musical way.
The main new feature of CUBE 2 is the ability to manipulate the analyzed sound spectra in a variety of musically useful ways: Imagine for example drawing a comb filter structure freely into the spectrum ! And you can do this not only in the sine spectrum, but also with the residual noise spectrum and the stereo panning.
The analyzer of CUBE 2 improved a lot and allows now specialized algorithms for different types of sounds. This includes harmonic / inharmonic and noisy sound types. The new residual noise generator of CUBE 2 allows you to create evolving noise spectra in a way which was never possible before.
Here are almost all of the new features of CUBE 2 at a glance:
