Syntrillium Software execs must be in a festive holiday mood after announcing that super-group Clear Channel Radio has standardized on Cool Edit Pro for its digital audio editing, recording and mixing. The supplier says Clear Channel has made “two major rounds of purchases” of software licenses for distribution to Clear Channel stations. Steve Davis is senior VP for capital management for the radio group. Bob Ellison is president of Syntrillium. Syntrillium said the software’s primary application at Clear Channel is for creating promotional and commercial spots.
