Digital Processing and Signal Analysis of Computer-Generated Acoustic Output for Application as Modulated Audio Identifiers

In this study, a series of computer-generated acoustic signals were created for evaluating their potential application as modulated audio identifiers. When the acoustic signal generated by an electric musical instrument was digitally recorded, it was saved as the original audio pattern and then used for further modification. Based on the original audio pattern, four audio variations were digitally created for comparison and evaluation. Our analysis shows that those four computer-generated audio variations exhibited distinct acoustic features and demonstrated that they could potentially be implemented for application as modulated audio identifiers.
