Cuong, We don't have a 0-crossing location feature, but you can accomplish what you want by holding down Shift when you press Delete. This is called Crossfade Delete, and should remove the pop sounds you are hearing.

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<mailto:dangmanhcuong@xxxxxxxxx> Yahoo!
