MP3 format commonly designates files containing an elementary stream of MPEG-1 audio and video encoded data, without other complexities of the MP3 standard. MP3 formally was MPEG-1 Audio Layer III or MPEG-2 Audio Layer III and MP3 was directly descended from OCF and PXFM.

LAME is the most advanced MP3 encoder. LAME includes a VBR variable bit rate encoding which automatically selects MPEG-2 or MPEG-2.5 sampling rates as appropriate for human speech recordings which need only 5512 Hz bandwidth resolution. When performing lossy audio encoding, such as creating an MP3 data stream, there is a trade-off between the amount of data generated and the sound quality of the results.
