Subject:0dBFS (SF 4.5) Posted by: MoonicaDeenus Date:11/11/2002 9:30:41 PM What exactly is the voltage representation for Full Scale in Sound Forge 4.5? I routinely mixdown several audio tracks (in Cakewalk Pro Audio 9) to .wav format. When I open those .wav files in Sound Forge 4.5, peaks are sawed off at several points in the song...yet there is no clipping! Without altering the file, I can convert to RealAudio or .mp3; & upload to my site; or burn the .wav to CD. In every case, the file conversions & audio CD's have never clipped (as in "audible" clipping.) Is there some sort of auto setting I have missed? Is there a generous amount of headroom built in? Is "0" purposely scaled back? Thanks in advance. mark4man

The definition of clipping is when one gets 3 samples of 0.0dB in a row. Most equipment is not going to make this kind of clipping all that noticeable. If you get clips of 5 or more samples in a row, you'll be able to start hearing it. It also depends if the clipping is just individual transients or sustained. HTH, Joel
