RadioSonic was a Canadian radio program, which aired on CBC Radio 2 from 1997 to 2003. RadioSonic, which aired on Saturday and Sunday evenings, was originally created by combining two predecessor programs, David Wisdom's Night Lines and Leora Kornfeld's RealTime. Both Wisdom and Kornfeld initially remained as cohosts of the new program, which profiled Canadian indie rock and alternative music, as well as other performing arts such as comedy and spoken word poetry. In its second season, the program's format was changed, with the Saturday night episode becoming more music-oriented and the Sunday episode being reduced in length and serving more as a magazine-style show for documentary and cultural features.
