Abstract

An audio signal processor capable of both sampling and audio processing external audio signals is disclosed. The audio signal processor can sample anaudio signal and store it in a fixed store in a two function memory for later playback or manipulation. The processor can also audio process external signals in real time by splitting an incoming signal into two parts; processing one part such that it is time delayed and/or pitch shifted, or both, with respect to the unaltered part; and recombining the processed part and the unaltered part to achieve time delay effects such as flanging, chorus and echo. Moreover, the audiosignal processor can output samples from the fixed store and real time processed signals simultaneously to achieve complex sound combinations and auditory effects.
