librosa.util.buf_to_float¶

librosa.util.buf_to_float(x, n_bytes=2, dtype=<class ‘numpy.float32’>)[source]¶

Convert an integer buffer to floating point values. This is primarily useful when loading integer-valued wav data into numpy arrays.

Parameters:	x : np.ndarray [dtype=int] The integer-valued data buffer n_bytes : int [1, 2, 4] The number of bytes per sample in x dtype : numeric type The target output type (default: 32-bit float)
Returns:	x_float : np.ndarray [dtype=float] The input data buffer cast to floating point
