Understanding MPGA files

What is a MPGA file?

MPEG audio stream, similar to MP3

MPGA files, also known as MPEG-1 Layer 3 Audio files, are the audio tracks usually found embedded in MPEG-based videos and streaming files. Most MPGA files are encoded with the same compression algorithm as MP3 files. Thus, any media player that can handle MP3 files can also decode MPGA files. MPGA files are compressed audio filesand takes up less space when compared to WAV files. MPGA files are also commonly used in police investigations or for recording interviews. Since MPGA files are compressed, it is more difficult to tamper with the underlying audio because a user would have to decode the MPGA file to a more editable format and then re-encode the file, which would also inadvertently overwrite most of the file’s meta data. MPGA files are a widely accessible file format.
