I'm ticked...

The good news is that if you throw this particular NOW cd in the garbage and just get the promos/regular CD versions they happen to be available in lossless elsewhere.

That's one thing I haven't understood. Songs are mastered loud (sometimes excessively) for CDs, but once that file gets played on the radio the extra compression is so much more obvious. I've been noticing a trend lately of more and more 24 bit FLAC files. Maybe it's a sign of something to come.]]> Wed, 07 Jul 2010 12:36:40 +0000 https://top40musiconcd.com/forum/forum_posts.asp?TID=5619&PID=27036&title=lossy-sources-on-big-2009-hits#27036 https://top40musiconcd.com/forum/forum_posts.asp?TID=5619&PID=27016&title=lossy-sources-on-big-2009-hits#27016 Author: KentT

And they are shooting themselves in the foot with radio stations. MP3 doesn't like extra conversions in the audio chain. And when broadcasters take that lossy pile of junk and run it through their digital Optimod and their digital STL there is two conversions already. Guaranteed artifacts in the station audio ensuring crappy FM and AM listening. AAC is better about multiple generations but broadcast audio should be delivered uncompressed as BWF files or as CD Audio resolutions. And we should get the audio with minimal/no dynamic compression as well so we can process it better.

That's my experience with most lossy sourced tracks on CDs. Most of them seem to be from AAC files. I guess some people just really love iTunes and hit "Import CD" as soon as the CD is popped in haha.]]> Mon, 24 May 2010 09:10:00 +0000 https://top40musiconcd.com/forum/forum_posts.asp?TID=5619&PID=26631&title=lossy-sources-on-big-2009-hits#26631 https://top40musiconcd.com/forum/forum_posts.asp?TID=5619&PID=26630&title=lossy-sources-on-big-2009-hits#26630 Author: aaronk

Nick, the Now tracks leave behind a very "watery" artifact when canceling the channels with each other, but they do sound better than an mp3 when playing normally. I would have to guess they came from an AAC based on your description.

Not all of the AAC files are guilty of leaving behind heavy artifacts, though. I mentioned in another thread that I purchased "Sharp Dressed Man" (single version) on iTunes, and surprisingly, there are very few artifacts at all.]]> Mon, 24 May 2010 07:59:16 +0000 https://top40musiconcd.com/forum/forum_posts.asp?TID=5619&PID=26630&title=lossy-sources-on-big-2009-hits#26630 https://top40musiconcd.com/forum/forum_posts.asp?TID=5619&PID=26628&title=lossy-sources-on-big-2009-hits#26628 Author: Nick2341

What I find interesting is that AAC has less noticeable artifacts vs. MP3 when playing normally, but when you cancel the left or right channel over each other it has more of a "watery" sound. I'm no expert on how the encoding schemes work, but I wonder if the residual noise is fed through an FFT filter of sorts to help it stay out of the way of the main frequencies.]]> Mon, 24 May 2010 07:35:55 +0000 https://top40musiconcd.com/forum/forum_posts.asp?TID=5619&PID=26628&title=lossy-sources-on-big-2009-hits#26628 https://top40musiconcd.com/forum/forum_posts.asp?TID=5619&PID=26612&title=lossy-sources-on-big-2009-hits#26612 Author: Todd Ireland
