What s the code to generate mel-spectrograms from audio for training Generative AI models

Question

Can you tell me, if possible, with code help, what code generates mel-spectrograms from audio for training Generative AI models?

Answer 1

Here is a concise example of generating mel-spectrograms from audio using Librosa below:

In the above code, we are using Librosa. This library handles audio loading and spectrogram generation, Mel-Spectrogram, which is Generated with librosa.feature.melspectrogram and converted to decibels for better visual representation and Parameters  n_mels controls the number of mel bands, and fmax limits the maximum frequency.

Hence, this spectrogram can be used as input for training generative models like WaveNet or Tacotron.
