# writing a binary file for demonstration data = np.array([1.1, 2.2, 3.3, 4.4], dtype=np.float32) data.tofile('example.bin') # reading the binary file loaded_data = np.fromfile('example.bin',. The main benefits of fromfile() are: (sample_rate, <u4), # (byte_rate, <u4), (block_align, <u2), (bits_per_sample, <u2), (data_id, s4), (data_size, <u4), # # the sound data itself cannot be represented here:
