1. A combined audio processor and sampler comprising:

  • an analog input for receiving audio input signals to be processed;

    an analog-to-digital converter (ADC) for digitizing the audio input signals received from the analog input into samples;

    a two function memory for receiving the samples from the ADC having;

    a circulating store having a plurality of sequential locations for temporarily delaying the samples a predetermined amount, anda fixed store having independently addressable locations for storing the samples for playback;

    a digital-to-analog converter (DAC) for receiving the samples from the two function memory and converting them to analog output signals;

    a processing means for controlling manipulation of the samples, the processing means controlling the predetermined amount of delay imparted by the circulating store and selectively addressing the independently addressable locations in the fixed store; and

    ,output means under the control of the processing means for selectively combining the audio input signals and the output of the DAC into a final output signal to achieve time delay effects.
