#SCIPY IO HOW TO#
來自源代碼的簡化代碼: fid = open(filename, 'rb') try: file_size, is_big_endian = _read_riff_chunk(fid) # find out how to read the file channels = 1 # assume 1 channel and 8 bit depth if there is no format chunk bit_depth = 8 while fid.tell() < file_size: #read the file a couple of bytes at a time # read the next chunk chunk_id = fid.read(4) if chunk_id = b'fmt ': # retrieve formatting information fmt_chunk = _read_fmt_chunk(fid, is_big_endian) format_tag, channels, fs = fmt_chunk bit_depth = fmt_chunk if bit_depth not in (8, 16, 32, 64, 96, 128): raise ValueError('Unsupported bit depth: the wav file ' 'has -bit data.'.format(bit_depth)) elif chunk_id = b'data': data = _read_data_chunk(fid, format_tag, channels, bit_depth,is_big_endian, mmap) finally: if not hasattr(filename, 'read'): fid.close() else: fid.seek(0) return fs, data Data-type is determined from the file see Notes. data : numpy array Data read from wav file. 從源代碼 Returns - rate : int Sample rate of wav file.
