The standard for CD quality audio is a sample rate of 44.1kHz, and a bit depth of 16-bit. Anything below this and your audio is not considered High-Definition (HD) or High-Resolution.
WebBoth correspond to a sequence of data points that can be played back at a specified sample rate in order to play a sound. For a bytes object, each sample is stored as a set of two 8-bit values, whereas in a NumPy array, each element can contain a 16-bit value corresponding to a single sample. WebAs you can see above .wav and FLAC indicate 16-24bit and MP3 has 128-320kbps (bits per second). You can get an example of this by selecting any song on your computer.
