Lost in Transmission
WAMU-FM in Washington, D.C. tested a live broadcast of multiplexing to a Kenwood receiver, tells Starling, and it was heard by a test group of close to 150 people.
But multiplexing still has to operate in the same bandwidth as a single stream and so potential quality loss had to be analyzed. The 96 kilobit stream they tested was split into 64/32.
"Initially we thought that was inevitable and that there's going to be something of a hit here," Starling remembers. But the results were good. "In general, it sounds pretty good at 64 kilobytes."
