Abstract
A method for the simulation of a realistic reverse tape effect, in real time, comprising the steps of detecting the beginning of a note by monitoring the input audio signal to determine when the same exceeds a variable amplitude threshold for a predetermined period of time and initially modulating audio signal gain with a rising exponential, while simultaneously recording the note attack and initial portion of the note decay period in digital memory, and when the input note amplitude envelope has decayed to a predetermined percentage of its peak value, stopping recording and beginning playback of the previously stored portion of the note decay and attack dynamic, in reverse, with a fixed signal gain.
