Abstract
A data processing system for identifying an audio signal includes an audio sensor, a receiver module, a signal recognition module, and a receiver device. The receiver module receives audio data from the audio sensor. The receiver module transmits the audio data to the signal recognition module. The signal recognition module calculates time-varying vector arrays of octave band energies, and/or of fractional octave band energies, and calculates time-varying vector arrays of Mel-Frequency Cepstral Coefficients (MFCC) values based on the received audio data. The signal recognition module generates audio feature image data based on the vector arrays. The signal recognition module includes binary classifier machine learning models and inference models to identify the audio signal based on the generated audio feature image data. The signal recognition module transmits a notification message to the receiver device.
