Compression has become an integral ingredient of most music these days. At the same time it remains somewhat a secret science – a commonly misunderstood one. It’s a great pleasure to have the mastering engineer Barry Gardner from SafeandSound online mastering services to talk to us about how to learn compression. During his long career in music Barry has worked with people such as Terry Callier, Ronnie Wood, Craig David, Kano, Chick Corea and many others. Needless to say he knows his stuff. Time to pay attention.
