Erm, if you're using DFX
It's not really "reproduction", more just just playout.. you're mangling an already lossy signal quite badly.
Best of all is when people use "stream rippers" to record stuff- yer radio station plays out mpeg compressed (typically) content, into Optimod processing, which then gets recompressed for streaming, and then uncompressed, recompressed and written to disk on the client end, cascade code artifacts ahoy!
Of course, most people will rhapsodise about the "fidelity" if you just boost the high and low end somewhat, even if it sounds very little like the original.
