Desktop Mastering: Book Release
Our own past Chair and Committee Member, Steve Turnidge, has gone off and

knowledge regarding audio engineering principles and practical applications for
those wishing to enhance their own as well as their clients' work. In addition to
providing a step-by-step in-depth survey of a successful mastering plug-in chain,

Internet Audio Networking
with Bob Moses, Island Digital Media Group.
As the dust settles from the dotcom hoopla, one thing is for sure - Internet Audio is here to stay. Some industry pundits predict that online consumption of audio/video media will eventually eclipse brick and mortar commerce. But critics point out that online music sounds bad, and such a tremendous transformation will take years, perhaps decades, to complete. Moreover, downloading music to a PC and listening to it while seated at a desk is not exactly a replacement for listening to a CD in the comfort of the living room. Bob Moses spoke aboutt the lastest advances in the business and technology of Internet audio. He reviewed the trend toward home networks so that audio and video can be digitally transported around a home along with other computer data. We listened to a variety of audio compression formats.
