Fuction graph_spectrogram from W3 Trigger Word Detection

Is the following function a built-in function or pydub?

x = graph_spectrogram(“audio_examples/example_train.wav”)

Hi @yujin_yano

You probably misplaced the question in the wrong Specialization / Course section.

You’re right. It was deep learning course.

The first cell in the C5 W3 A2 notebook tells you that the td_utils.py function is imported.

If you go to the File menu and open that file, you’ll find the spectrogram plotting function.
