If they are to store stereo audio, the array must have two columns that contain one channel of audio data each. They must also have a signed 16-bit integer d-type and the sample amplitude values must consequently fall between -32768 to 32767. Below is the code to generate a NumPy array and play it back using simpleaudio.play_buffer().

A digitized audio signal is a NumPy array with a specified frequency and sample rate. The analog wave format of the audio signal represents a function (i.e. sine, cosine etc). We need to save the composed audio signal generated from the NumPy array. This kind of audio creation could be used in applications that require voice-to-text translation ...

The file can be an open file or a filename. The returned sample rate is a Python integer. The data is returned as a NumPy array with a data-type determined from the file. Example: variable1,variable2 = scipy.io.wavfile.read(‘example.wav’) Below is the actual Python Script that records the duration/length of any audio file:
