Abstract :
As continuing support of National Public Radio´s Tomorrow Radio project, this paper presents results from a consumer study conducted with iBiquity´s HD Radio codec. Forty participants judged the quality of the HD codec (HDC) at various bit rates, ranging from 16 kbps to 96 kbps. A range of musical and speech genres were tested. This study provides in-depth information intended to help broadcasters select optimal bit rates when HD Radio´s 96 kbps data stream is shared between primary and supplemental channels.
