To convert audio files into such a smaller format, they need to be compressed. Audio compression is available in two forms: lossy and lossless. MP3s are converted using lossy compression. This means, that to get the file size as small as they are, some of the sound quality is lost. A process called temporal noise shaping decides which audio

Sound files must be: WAV files in standard PCM format. 16-bit with 44.1 kHz sample rate. Mono format. Stereo format will be automatically converted to mono. 30 seconds or less in length. On Unix and Unix-like operating systems (including macOS), the command file audiofilename.wav will produce something like:Your array of bytes won't just be audio data, it all also include the various headers that describe the file. I assume scipy.io.wavfile.write will also attempt to write its own headers, so the headers in your bytearray will be interpreted as audio data, with audio garbage being the result.
