VOC is an audio file category format. File format VOC (or Creative Labs Audio File) was created by Creative Labs. Creative Labs was involved in the development of the audio file format in order to store and transfer audio data for its 8-bit and then 16-bit Sound Blaster sound cards. The format is a sound effect, sound clip and instrumental sound, referred to as a voice. To reduce the size, VOC files are compressed. Since this format has already been thoroughly investigated, its file structures have already been described in detail. A .voc file is a digital audio file in VOC format. In the title, it can be easily identified by the text line “Creative Voice File”. The file includes a header, as well as one or more blocks of audio data. Due to PCM / ADPCM audio encoding, VOC files can be easily converted to WAV format. VOC audio files can be played by several universal multimedia players. Sound editors import them. Using many utility converters, you can convert other audio formats to WAV. In many cases, the .voc file type becomes associated with some kind of multimedia processor that is installed on the system.
