MP3 encoder

MP3 (MPEG Audio Layer III): A popular lossy audio format that revolutionized digital music distribution by compressing files while retaining a reasonable sound quality.

An MP3 encoder can convert audio streams into MP3 files or embed MP3 audio streams in formats like AVI, MKV, and others.

Use the MP3EncoderSettings class to set the parameters.
