# MP2 encoder

Media Blocks SDK .Net

MP2 (MPEG-1 Audio Layer II): An older, lossy audio compression format that is less complex than MP3, commonly used in broadcasting and digital radio due to its robustness.

An MP2 encoder can be used to encode audio streams in formats like MPEG-TS or VOB.

Use the MP2EncoderSettings class to set the parameters.
