read(filename[, mmap])
- Open a WAV file.
https://docs.scipy.org/doc/scipy/reference/generated/scipy.io.wavfile.read.html#scipy.io.wavfile.read
- Return the sample rate (in samples/sec) and data from an LPCM WAV file.
- rate:int
- Sample rate of WAV file.
- data] numpy array (numpy.ndarray)
- Data read from WAV file. Data-type is determined from the file; see Notes.
- Data is 1-D for 1-channel WAV, or 2-D of shape (Nsamples, Nchannels) otherwise.
- If a file-like input without a C-like file descriptor (e.g., io.BytesIO) is passed, this will not be writeable.
