How to force a file to be MPEG-1, MPEG-2, or MPEG-2.5?
https://hydrogenaud.io/index.php?topic=113999.0
The three audio compression layers are defined in MPEG-1, MPEG-2, and MPEG-2.5, of which the first two are the official standards, and the third one is proprietary and unofficial. In total, there are basically nine encoding versions, but how can I safely distinguish the nine versions form one another?
MPEG-1 and MPEG-2 Layer II Audio Encoding
https://www.loc.gov/preservation/digital/formats/fdd/fdd000338.shtml
MPEG-1 Audio Layer II is defined in ISO/IEC 11172-3. An extension of MPEG-1 Layer II is defined in ISO/IEC 13818-3, which adds more sampling and bit rates as well as support for up to 5 audio channels. Production phase: Generally used for final-state, end-user delivery. Relationship to other formats; Subtype of: MPEG-1, MPEG-1 Video Coding (H.261)

Abstract. This chapter describes the MPEG-2 Audio coding family which was developed to extend the MPEG-1 Audio functionality to lower data rate and multichannel applications. First we will discuss MPEG-2 LSF and “MPEG- 2.5” systems in which lower sampling frequencies were used as a means to reduce data rate in MPEG-1 audio coding.

MPEG versions available are MPEG-1, MPEG-2, MPEG-4, MPEG-7, MPEG-21 etc. These are used as standards for general coding of Moving Pictures and Associated Audio. The syntax of compressed video and audio bitstreams will enable great amount of flexibility at the encoder.
MPEG-2 - Wikipedia
https://en.wikipedia.org/wiki/MPEG-2
The MPEG-2 Audio section, defined in Part 3 (ISO/IEC 13818-3) of the standard, enhances MPEG-1's audio by allowing the coding of audio programs with more than two channels, up to 5.1 multichannel.This method is backwards-compatible (also known as MPEG-2 BC), allowing MPEG-1 audio decoders to decode the two main stereo components of the presentation.
