IBUZZ-THE TRUTH ABOUT HD RADIO-UNMASKED!
IBUZZ HD RADIO-DEFECTIVE TECHNOLOGY!
The most elegant encoding algorithm in the world cannot produce "near-CD quality" sound with such limited bandwidth (considering uncompressed CD audio has a bitrate in excess of 1,400 kbps, HD Radio signals convey less than 10% of the original program audio data).
An HD Radio signal is essentially a hybrid analog/digital signal. Its configuration keeps the analog portion of the signal nearest the center frequency and puts the digital data on "sidebands," which are broadcast at 1/100th the power of the analog signal. Thus listeners should expect the coverage area of multicast channels (especially new secondary channels) to be somewhat limited.
