The format includes various types of multimedia content: videos, animations, audio, 2D and 3D graphics. Files of this format can be used and viewed on the Internet.

mp3

MP3 (more specifically, MPEG-1/2/2.5 Layer 3; but not MPEG-3)

A standardized file for storing audio information. Supported by virtually all music players and playable on almost all mobile devices. When the audio data is compressed, the sound quality decreases, albeit insignificantly. The compression process erases the frequency that is imperceivable to the human ear. This format allows you to save storage space. You can store and send the audio files after compression. The MP3 format was developed by the German company Fraunhofer IIS. The user can adjust the compression ratio and the audio file quality.
