MIDI data is not digitized sound; it is a shorthand representation of music stored in numeric form.
The file size (in bytes) of a digital recording is sampling rate * duration of recording in seconds * (bit resolution / 8) * number of tracks (1 for mono, 2 for stereo)

Codecs are digital video and audio compression schemes that compress a video into a container for
delivery and then decode it during playback.
