Abstract: A method and apparatus are described which reduce the presence of an unwanted signal. According to one embodiment, a first signal is provided from a desired location that includes an unwanted signal while a second signal is provided from an alternate location (e.g., one where the unwanted signal is less of a proportion of the total signal). The first and alternate signals are provided to respective signal processors. A level for a selected frequency band of the first and alternate signals is adjusted so that an increase in one results in a decrease in the other. Doing so allows the frequncy band that includes the unwanted signal to be reduced in the desired first signal and filled in with a similar frequency band from the alternate signal.

Abstract: Embodiments of a method and apparatus are described which provide for a consistent, continuous and/or repeating signal. Such a repeating signal may be used to set the controls for a processor. For example, an embodiment of a preview sampler described herein allows a user to repeatedly output a data segment into a processor so that the processor can be adjusted to achieve a desired effect. Such a method and apparatus provides improved results when compared to an individual attempting to repeatedly generate a data signal (e.g., a note or chord on a musical instrument).

Abstract: A method and apparatus for level compensation is presented to compensate for signal level changes made by a signal processor. The original, unprocessed input signal and the output signal from the signal processor (e.g., an equalizer) are provided to a comparison unit which determines a difference in signal level between the two signals. The output of the comparison unit is provided to a level compensator along with the output signal from the signal processor. The level compensator then modifies the signal level of this output signal (e.g., matches it to the original, unprocessed input signal).
