What you'll learn

  • Raw audio waveforms must be transformed into structured numerical representations to enable effective processing by machine learning models.

  • Spectral features, STFT, MFSCs, & cepstral features, MFCCs, capture complementary signal info supporting ML classification, detection, recognition.

  • Noise injection, time-shifting, pitch modification & speed adjustment improve model generalization in real-world acoustic environments.

  • Automated audio augmentation pipelines are essential for production-ready AI systems ensuring reliable performance across diverse conditions.
