How Do You Know?

How do you know if what you’re downloading or listening to is really HD? Well, first we have to define what high-definition audio actually is. It turns out that this is not an easy task. Click on the video to the left to get an overview of how I define HD-Audio. While others might regard their favorite audio format as “high-definition”, clearly not everything ever produced and/released qualifies as HD nor are all formats equally capable of delivering high quality audio. But maybe that’s OK.

That’s why this site was launched to discuss and explore the realities of audio formats.

Mark Waldrep, aka Dr. AIX, has been producing and engineering music for over 40 years. He learned electronics as a teenager from his HAM radio father while learning to play the guitar. Mark received the first doctorate in music composition from UCLA in 1986 for a "binaural" electronic music composition.

Dr. Waldrep has been an innovator when it comes to multimedia and music. He created the first enhanced CDs in the 90s, the first DVD-Videos released in the U.S., the first web-connected DVD, the first DVD-Audio title, the first music Blu-ray disc and the first 3D Music Album. Additionally, he launched the first High Definition Music Download site in 2007 called iTrax.com.
