Hi,

As I already posted in the other thread, I released a tiny tool for Windows to access the QuickTime AAC encoder from the command line. Now some important features, gapless support and pipe encoding, have been added, so I've decided to create a dedicated thread for this software.

You can get the latest version here.

Any comments or questions are accepted in this thread.
Thanks

I implicitly trust lvqcl, so I won't continue to make an issue out of this except to say one can easily take a loud and likely "clippressed" track that routinely peaks at full-scale, encode and then decode to see if it has a reduction in level.

How do you think did i noticed it?
And why don't trust "seems" but "looks like"?
Am I stamped as a liar somehow? mad.gif
