All audio file must be saved as .wav in the ./data directory.

Once you have downloaded your audio files, you are tasked with pre-processing your data by converting the raw waveform to a spectrogram using the Fast Fourier Transform (FFT). You can find more information about the FFT HERE Finally, your must convert your spectrogram from Hz range to the mel-scale. More information about me-scaling can be found HERE

Note: You are not permitted to use built-in functions to perform FFT and mel-scale operations mentioned in part 2.
