VOC is an audio file format developed by Creative Labs for storing sound data on Sound Blaster sound cards. VOC files can contain voice recordings, sound effects, and music. While it was popular in the early days of computer sound, it is now largely obsolete, with MP3 and WAV taking over as more common formats.
MP3 is an audio format that can compress and encode an audio file. It uses the lossy compression algorithm to contain audio data. The lossy compression helps to reduce the data significantly without losing audio quality. MP3s are created using different bit rates maintaining the original quality.
