The math.pi is defined as the ratio of the circumference to the diameter of a circle.Spectrum Analyzer. This audio spectrum analyzer enables you to see the frequencies present in audio recordings. The spectrum analyzer above gives us a graph of all the frequencies that are present in a sound recording at a given time. The resulting graph is known as a spectrogram . Deep learning models rarely take this raw audio directly as input. As we learned in Part 1, the common practice is to convert the audio into a spectrogram .The spectrogram is a concise 'snapshot' of an audio wave and since it is an image, it is well suited to being input to CNN-based architectures developed.
