Description

SUMMARY

[0013] Summarized, the process is one which analyzes a selected sample of audio waveform to generate an automated placement of calculated reversals over portions of the sample. The result is a perceivable audio effect like distortion, reverb, delay, etc. The result is achieved by first finding the samples articulation measurements. Then, the reversals are applied to calculated portions of the sample articulations (within the middle/center of each articulation) to produce a desired effect. The onset and duration parameters of applied reversal (otherwise defined as the “portion” of audio being reversed) is calculated based on a desired level of this creatable effect. The correct portion parameters of which to apply reversals can be calculated using measured waveform/articulation properties, by calculating the reversal parameters as they will respond the output result based on waveform characteristics accordingly. For example, if I want a glitchy or choppy result of this effect, the reversal parameters can be calculated by a. selecting this level of desired effect, b. determining what reverse parameters are applicable to create this effect based on waveform properties, and c. applying such reversal parameters to achieve the desired effect. In some instances, reversing the entire center of the articulation will produce the desired effect. In other scenarios, the desired effect may entail reversing a small portion of “the inner-most center”, slightly offset or shifted to the left. Similarly, waveform properties will render the need to calculate the reversal placement for each articulation individually to more accurately create an application of this effect. A skilled audio engineer will be familiar with waveform property and pattern definitions correlative to the application of reversal functions of this invention. A skilled software will be able to utilize audio spectrum finite rules relating to applied reversal scenarios to specific wave shape generalized scenarios. Further a database of memory programmed functions or processing rules can integrate calculated, observed rules associated with definite property/elements pertaining to waveforms/shape/type generalized definitions or types, as their inherent waveform properties are predictably reactant in specified manners pursuant to a specified, application of the reversal function of this invention. The inherent finite properties of the audio processing functions further are integrated into a user friendly graphic software interface for the control and dictation of the invention/functions.

[0016] 3. Articulation data is defined, measured;

[0017] 4. A selection of a level or “intensity” indicative of one or more audio spectrum measurable properties are, selected.

[0018] 5. The waveform properties are measured against the selected spectrum parameters to calculate the best possible placement parameters(portions) of the applied reversal instances;

[0019] 6. As calculated, a portion of each articulation (in the middle or center) is reversed accordingly to said calculations;
