There are some advantages to a "quiet" sweep - avoids overloading the mic/input (although as long as the recordings stay below clipping that should never be a problem) - reduces heating-based and other distortion in the loudspeakers (generally); I think most speakers are more linear with low-level signals than with high - keeps friends & neighbors from calling local enforcement officials...
On the other hand, background noise becomes more of a problem. With very loud spweeps there's a distinct risk of blowing tweeters, too. Hence my recommendation to set volume by playing the pink noise test signal at a level which sounds "loud but not uncomfortable". I've tinkered around a bit with trying to understand how sweep-triggered noise (harmonic distortion, rattling china, etc) affect the measurement of the impulse response, but haven't come to any good conclusions yet. I tend to think that "booming" (resonating cabinets, etc) is OK since it's pretty much a linear effect, where "rattling" is probably undesirable. -- inguz ------------------------------------------------------------------------ inguz's Profile: http://forums.slimdevices.com/member.php?userid=1139 View this thread: http://forums.slimdevices.com/showthread.php?t=26005 _______________________________________________ plugins mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/plugins
