To convert a .wav file to a spectrogram in python3, we can take the following steps −Load a .wav file from local machine.Compute a spectrogram with consecutive Fourier transforms using spectrogram() method.Create a pseudocolor plot with a non-regular rectangular grid using pcolormesh() method.Use imshow() method with spectrogram.To display the figure, use show() method.Exampleimport matplotlib.pyplot as plt from scipy import signal from scipy.io import wavfile plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True sample_rate, samples = wavfile.read('test.wav') frequencies, times, spectrogram = signal.spectrogram(samples, sample_rate) plt.pcolormesh(times, frequencies, spectrogram, shading='flat') plt.imshow(spectrogram) plt.show()Output
Read MoreHow i can replace number with string using Python?
For this purpose let us use a dictionary object having digit as key and its word representation as value −dct={'0':'zero', '1':'one', '2':'two', '3':'three', '4':'four', '5':'five', '6':'six', '7':'seven', '8':'eight', '9':'nine'Initializa a new string object newstr=''Using a for loop traverse each character ch from input string at check if it is a digit with the help of isdigit() function. If it is digit, use it as key and find corresponding value from dictionary and append it to newstr. If not append the character ch itself to newstr. Complete code is as follows:string='I have 3 Networking books, 0 Database books, and 8 Programming ...
