Abstract
The global spectral envelope is particularly important in the perception of sound. The use of a parallel bank of linear phase FIR filters for a versatile and high quality acoustic synthesis is suggested. The dynamic parameter control techniques (center frequency, bandwidth, amplitude and shape) starting from lowpass prototype filters are studied. Finally, two implementation models with different control modes are presented.
