This one is easy. MP2 files “Just Work”.&lt;br /&gt;
&lt;br /&gt;
In fact, [[MPEG-1_Audio_Layer_II|MPEG-1 Audio Layer II]] (MP2) is one of the three Rivendell “native” file formats, the others are 16-bit and 24-bit [[Pulse-code_modulation|PCM]] [[WAV]].&lt;br /&gt;
&lt;br /&gt;
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.&lt;br /&gt;
