Hugh Robjohns has been Sound On Sound's Technical Editor since 1997. Prior to that he worked in a variety of (mostly) sound-related roles in BBC Television, ending up as a Sound Operations Lecturer at the BBC's technical training centre.
He continues to provide audio consultancy and bespoke broadcast audio training services all over the world, lectures at professional and public conventions, and occasionally records and masters acoustic and classical music too!
I work in a facility where AES3 110Ω cables have been used to connect some splitter outputs to mic preamps. What kind of influence, if any, can this ‘impedance mismatching’ have on the signal quality?
I understand that data-compressing audio files is really just chopping out frequencies we think we don't need, but I don't understand what encoders do to go the other way.
