Play It Again, Sam
This one is easy. MP2 files “Just Work”.
In fact, MPEG-1 Audio Layer II (MP2) is one of the three Rivendell “native” file formats, the others are 16-bit and 24-bit PCM WAV.
In “olden days” decoding MPEG-encoded files was a job some considered too hefty for a PC CPU. So manufacturers created audio cards with codecs in hardware to speed the process. These days (Early Twenty-first Century) with on-board floating point, blazingly fast clock rates, multiple CPUs and threads, and other standard hardware support, it is a simple job to encode and decode audio files in real time.
