To expand on the other response to this question. Foobar and other good software for creating RG tags will create tags for each track and a whole album based on some fixed level you want to average all your tracks to. And, most software for playing music will read those numbers and make its own adjustments if you have settings there for averaging. Depending on where your target is, clipping may occur because the RG is just for an average while many peaks will still be peaks and could clip. Maybe the track was on average a 90 and you are targeting 95. Well if the track was a 90 because some peaks were at 99, then shifting everything by +5 would cause clipping. Most software, when evaluating for RG, will also identify the peaks and either limit the RG tags so that these don't clip or provide a basis for other software to make that decision. I suspect that the higher your target average is, the more likely you are to be in a situation where the peaks will exceed the dynamic limit where clipping will occur and the software will be setting RG tags to prevent clipping rather than to meet an average. Consequently, you might hear a difference if the RG is varying itself to prevent clipping rather than to create an average sound. However, if you set your target average at a lower value, then the music will now be RG to the average you want, without peaks being clipped, and you will be less likely to hear a difference in volume. Now, this is somewhat theoretical as I've never looked that close to know this is exactly the case. Conceptually, the above would be critical regardless of the music genre, but classical generally has more dynamic range so perhaps it is more likely to accidentally set RG values too high or end up with the clipping situation and volume discrepancy that could occur in the situations above. Remember that the main purpose of RG is so that when you listen to music from multiple albums, that you aren't having to adjust the volume from track to track or album to album. However, if the peaks are getting into the way because the RG settings are too high, you could still be in that situation. I've not experienced this myself, but I generally set my RG in LMS and in Foobar or other analyzing software to target at around 90. That seems to work, and I generally don't find myself changing the volume except when I get surprised when I switch over to streaming (which generally doesn't have RG) and the jump in volume startles me. ------------------------------------------------------------------------ emalvick's Profile: http://forums.slimdevices.com/member.php?userid=35382 View this thread: http://forums.slimdevices.com/showthread.php?t=110369 _______________________________________________ ripping mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/ripping
