In python, I'm going to create a spectrogram from a .wav file
Like this image, I want the final saved image similar to this
I just need a spectrogram that has many colors. I also tried tinker with this code, to give a try and add the colors, but after spending too much time, I couldn't able to figure it out.
When I tried this tutorial
In this code, on the 17th line, the code got crashed, when I tried to run the code with the error
TypeError: 'numpy.float64' object cannot be interpreted as an integer.
samples = np.append(np.zeros(np.floor(frameSize/2.0)), sig)
I also tried fixing it by casting
samples = int(np.append(np.zeros(np.floor(frameSize/2.0)), sig))
Tried in this way too,
samples = np.append(np.zeros(int(np.floor(frameSize/2.0)), sig))
None of these worked. I just need to know how to convert my .wav file to spectrograms with many colors, so that it would be helpful for me to analyze them.
