Application of wireless sensor network and audio anomaly detection in oboe timbre training

Abstract

This study suggests combining wireless sensor networks (WSNs) into audio anomaly detection methods to further improve timbre training for oboe players. Basically, WSNs capture information regarding real-time measurement of parameters such as breath pressure, embouchure, and the actual moments of sound features, serving as a backbone of scientific data-driven music education. Thus, the application of audio anomaly detection permits the assessment of the quality of oboe sound and the giving of real-time feedback on any musical performance. The audio data is preprocessed such as noise elimination, resampling, and removing silence so that it is stable and free from any extraneous influences. Sound anomalies are identified through a hybrid method that uses Variational Autoencoder (VAEs) combined with Convolutional Neural Networks (CNNs), enabling us to strongly evaluate oboe performance. The system is tested with an assortment of performance measurements: accuracy at 98.18%; precision at 97.12%; recall at 97.34%; and F1-score at 97.55%. Hence, it showcases a capability to provide exceptional performance to identify variation from the standard in audio signal. The approach in question is addressing some key challenges in oboe training, breath control, and accuracy of embouchure, thus providing musicians and instructors with valuable tools for sound quality improvement and performance analysis.
