Support Vector Machine Classification of Microarray Data

Apparatus for enhancing the sound quality of musical instruments and of electronic sound sources is disclosed. Electrical signals representative of sound are modulated in a predetermined manner to increase their spectral content and are then processed by a resonance network which alters the amplitude and phase relationships of the various harmonic signal components. The processed signals are then demodulated in accordance with the modulation method used, thereby recreating a distorted replica of the original tone which is rich in harmonics that are uncorrelated in amplitude and in phase with each other. Upon conversion to sound this demodulated signal results in a pleasing tone.
