Hi all I'm interesting of using Studio recorder to cut out unwanted part in my recorded file. However I record my audio at my room, not studio. So if I want to cut out the silence part, I usually hear a small click after cutting. This problem can be solved with some other program with the options called Find zero crossing. But with studio Recorder, I don't know it support or not, and how to do it. Any help would appreciated Cuong. ________________ Dang Manh Cuong HCMC University of Pedagogy: The Educational Psychology Mobile: +84 902-572-300 E-mail: dangmanhcuong@xxxxxxxxx Yahoo!
