scipy.io.wavfile.read is a convenience wrapper to decompose the .wav file into a header and the data contained in the file.. From the source code. The code for reading the file could be summarized as follows: import scipy.io.wavfile as wav (sig, rate) = wav.read(_wav_file_) For some .wav files I … data : numpy array Data read from wav file. Data-type is determined from the file; see Notes. The Overflow Blog
The sampling rate returned by Thanks for contributing an answer to Stack Overflow! I am trying to load a .wav file in Python using the scipy folder.
I also think thnq you for replying, i used this library and successfully read it but there was a problem with ram when huge amount of data are read. In [1]: import scipy.io.wavfile as wav In [2]: rate,f=wav.read('980__rhumphries__rbh-glass-break-04.wav') This gives me the following error: "ValueError: string size must be a multiple of element size" Since the function is working fine with all the other wav files that I have I suspect that this is a bug.
