Abstract
A dry/wet bit for controlling dry and wet components of an output sound during processing of an input sound is provided. The bit is configurable by a program to indicate when to reverse the dry and wet components of the output sound. When the bit has a first value, the dry component is calculated by modifying the input sound by an attenuation factor, and the wet component is calculated by providing to a reverberation filter as input the dry component modified by a reverberation factor. When the bit has a second value, the wet component is calculated by providing to the reverberation filter as input the input sound modified by the attenuation factor, and the dry component is calculated by modifying the input to the reverberation filter by the reverberation factor.
