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.
WMA is a digital audio format developed by Microsoft, primarily used for music and audio streaming. It offers high compression while maintaining good sound quality. WMA files are supported by Windows-based devices and media players, but are less compatible with other operating systems compared to MP3.
