What have people who listened to the radio regularly ever experienced?
Anyone who listens to the radio regularly, AM, FM and short-wave, has experienced the annoyance of signal distortion. Technical types call the reception problem "multipathing". What it means is that, on their way from transmitters to your home or car, the radio waves sometimes get sidetracked by tall buildings, tunnels, passing trains or your whirling hair dryer. In five years or so, there will be still passing trains and hair dryer--but radio interference could well be a memory. Digital radio is coming, and it promises to bring to future listeners distortion-free music that matches the quality of compact discs. Supporters of the technology say the sound will be so clean that people will record songs and programs directly off their home receivers.
Digital radio wont lie available until 1995 or 1996, at the earliest. When it does arrive, perhaps first in Canada, it could help radio stations in advanced countries compete with CDs, digital cassettes and emerging digital cable service. Its impact in developing regions such as Africa and the Caribbean, where radio coverage is spotty and programming insufficient, could be even bigger. In those places, digital radio developed by satellites could bring the world to scattered listeners.
