You've got source files that are below your desired target volume, and they're already near/at/beyond the clipping point. This means it is impossible to turn the volume up with a simple linear operation and not have clipping. To meet your -10 target you need to turn that -12.9 source up by 2.9 dB (nearly a 100% increase!) and the source appears to already be clipping, given what the TP value is in this example. The only way to make this louder is to use dynamic compression in the process, and thus your dynamic range will be reduced. That's just part of the deal. You can't compress peaks without reducing dynamic range. Compressing peaks reduces dynamic range by definition. If your goal here is to match volumes so you never have to adjust the volume on your amplifier you'll have to come up with a target volume that is lower so that most/all of your sources will have to be turned down rather than trying to turn some of them up. At least, if you want to avoid having to use dynamic compression in the process. Turning things down a little bit in the file isn't a big deal since you can (presumably) compensate in the playback system by turning the amplifier up. You'll lose less than you will by turning things up in the file and using dynamic compression in the process. -- Clayton Macleod If no one comes from the future to stop you from doing it, then how bad of a decision can it really be? _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
