    initial v1  
    6969Files have a CD-quality, two-channel signed 16-bit Linear PCM sampled at 44,100 Hz. The audio bit rate for a Red Book audio CD is 1,411,200 bits per second or 176400 bytes per second; 2 channels × 44,100 samples per second per channel × 16 bits per sample. We extract 30 seconds, so audio data size must be 5292000 bytes (176400*30). The WAV header has a 78 bytes size, so the total size of file must be 5292078 bytes. For the from_wav.wav file is true, but from_ape.wav is smaller.
