I recently posted a video demonstrating how Apple's Sound Check feature works, and exploring whether it really means that the loudness war has been won as Bob Katz claims.

The short answer is - I hope so, but I do have reservations.

But even if Bob is right (and there are encouraging signs that perhaps the loudness war tide is turning, recently) I've still always had a reservation about Sound Check.

It evens out all the levels on albums, too - as well as when you're listening on shuffle.

This is a huge negative point, for me - Sound Check alters all the internal dynamics within an album - the contrast between quieter and louder tracks.

Or at least, it used to.

Tests made recently by Bob and others suggest that Apple have implemented a fix for this problem and quietly rolled it out, without any fanfare.

Of course I wanted to try this for myself, and I made the video above to demonstrate what I found. I also discuss why I think it's important, what I think Apple's next step should be - and why that decision could be a really big deal.
