Subject:How does SF define Clipping? Posted by: msterlin Date:11/4/2003 10:31:37 PM I understand that clipping is defined as N consecutive maximum value samples and my observation from using SF Studio 6.0e to rip cds is that it uses N=2. However, occasionally i have a song that lights the clip indicators even though I don't see 2 or more consecutive max samples. Is it that clipping is also indicated if there are 2 or more max value samples within the time resolution of the meters? IE, if the meters are updated every 300 ms and there are 2 or more max samples within 300ms of each other, the clip indicator lights.
Subject:RE: How does SF define Clipping? Reply by: Soundshepherd Date:11/6/2003 5:13:34 AM We need user-defined clip definitions. This is very important for some people who move into the DAW world from working 10+ years with a DAT machine that used (for instance) 10 consecutive samples as its definition of clipping.

I tried your experiment and the answer is 4 - one more than the number of bites it takes to get to the tootsie roll center. :) It's mainly mp3 i create from waves ripped from cd that show the occasional clip, although some songs are clipped right on the cd. Its inaudible so I probably shouldn't worry about it, but I just wanted to know what standard SF is using.
