HD Radio is great. Vastly improved sound quality (on fm, anyway), and more important...more VARIETY (with "multicasting"...allowing a single station to simultaneously broadcast multiple programs...known as "channels", or "streams"). But if none of those extra channels interest you, it's just so much background noise.
I often tell my wife that there's not much on radio that I enjoy listening to (despite 33 years in the business). I enjoy soft music, primarily instrumental. Go ahead, use the "New Age" label if you like. That's cool, as Windham Hill has stayed in business the last few decades largly due to my contributions "to the cause". Last night I discovered something on the radio in my area that I really love. WFAE Charlotte (90.7 FM) has a Sunday evening show called "Nightscapes"...three hours of instrumental, "new age" music. I freakin' love it! Perfect music to soothe the soul! It's even in HD, and sounds very good. Not perfect, because WFAE has THREE HD streams, and consequently divides their data-stream three ways. Still it was bright, crisp, "full" soundinding...clearly better than analog fm, and the music was GREAT. I'll be listening next Sunday, and on the Sundays that follow! If you're ever in Charlotte (or HIckory...where it's simulcast on 90.3 WFHE), check it out!
This joins "The Shuffle Channel" on WLYT (Charlotte, 102.9) as my co-favorite HD offering to-date.
