Preprocessing Audio: Digital Signal Processing Techniques. Dataset preprocessing, feature extraction and feature engineering are steps we take to extract information from the underlying data, information that in a machine learning context should be useful for predicting the class of a sample or the value of some target variable.

The pyAudioProcessing library classifies audio into different categories and genres. At a high level, any machine learning problem can be divided into three types of tasks: data tasks (data collection, data cleaning, and feature formation), training (building machine learning models using data features), and evaluation (assessing the model).

proposed method to audio classification. For preprocessing, the Mel spectrogram is used to represent the audio signal in a more descriptive manner. Transfer learning and a smaller CNN architecture are implemented to accurately classify our audio data. The following section details our raw audio preprocessing and the Mel spectrogram. III.
