OPUS is an efficient audio codec optimized for both speech and music, widely used for internet streaming, video conferencing, and VoIP. It supports low latency and high-quality audio compression, making it ideal for dynamic network conditions. OPUS maintains high audio quality while significantly reducing file size, ensuring fast transmission and playback. Recommended players include [VLC](https://www.videolan.org/) and [Foobar2000](https://www.foobar2000.org/).

MP2 (MPEG-1 Audio Layer II) is the second layer of the MPEG-1 audio coding standard, widely used in digital broadcasting, DAB (Digital Audio Broadcasting), DVB (Digital Video Broadcasting), and early digital audio storage.
