Its purpose is to amplify the signal by a user selectable amount, then smoothly reduce gain for those samples that clip as a result. This allows listening to dynamic material in noisy environments that could drown out quieter passages, sort of a smart volume control. This version is ready to commit, at least to see if it's going to break on some targets, those with small amounts of IRAM for instance. It may be the case that it should be disabled on some targets. I've been running it on my Sansa E280 for a few weeks and it works well there. I've streamlined the code so that when the process isn't active, it doesn't affect normal operation. Unlike earlier versions, as long as it isn't active, it's completely transparent to normal operation. Please apply the patch to your favorite player and try it out for a bit. I'd like the feedback and blessing of the dev group before committing something this large.
