Abstract
The disclosed subject matter includes, in one aspect, a signal processor having circuitry configured to substitute an assortment of pre-recorded sounds in place of the sound of the guitar. The pre-recorded sounds are triggered by a guitar note that is above a certain threshold. The threshold can be varied, as can the length of time of the substitution.
Claims21
A sound processor for substituting one or more pre-recorded sounds for a live sound upon receipt of an input signal sound, comprising:
- a threshold detector circuit configured to receive the input sound signal, compare the input signal to a threshold, and output a trigger signal if the input sound signal exceeds the threshold;
- a timer circuit configured to receive the trigger signal and output a one-shot pulse of a first duration;
- a sound selection circuit configured to receive the one-shot pulse and select and output one of the one or more pre-recorded sounds;
- and
- an output selection circuit configured to receive the one-shot pulse and select and output an output signal from the at least one pre-recorded sound and the input signal.
A sound processor for substituting one or more pre-recorded sounds for a live sound upon receipt of an input signal sound, comprising:
- threshold detection means for receiving the input sound signal, comparing the input signal to a threshold, and outputting a trigger signal if the input sound signal exceeds the threshold;
- timing means for receiving the trigger signal and outputting a pulse of a first duration;
- sound selection means for receiving the pulse and select and outputting one of the one or more pre-recorded sounds;
- and
- output selection means for receiving the pulse and selecting and outputting an output signal from the at least one pre-recorded sound and the input signal.
