Hey Oz, in case you're still here...
Speaking of digital testing as it were, I was going to say (before I got interrupted earlier) that I've noticed the channel I listen to regularly online, www.radioparadise.com, has been sounding increasingly better. The guy and his wife do a lot to get the best sound they can and they have a great format IMO.
We've e-mailed before about this, so I e-mailed him again yesterday and he wrote back:
...and so on.Hi Art,
I've made a few tweaks to our signal processing, though it's still the same gear. About a year ago, I introduced the ability for me to tag songs with a playback level value, boosting the level of some older recordings by as much as 4db, and reducing the level of some heavily-compressed newer recordings by as much as -6db. This allowed me to greatly reduce the amount of overall gain control on our stream. That's a pretty significant change. I have also made a number of improvements to our source files over the past 2 years or so, often replacing older versions with remastered versions.
If you're listening via one of our apps on iOS or Android, I'm in the middle of a really major overhaul of the audio quality. Rather than applying global audio processing, each sound file is processed individually for uniformity in level & spectral density -- meaning virtually no processing at all other than overall level control in the case of modern masters, and a tailored bit of de-facto remastering of my own on older recordings. It sounds quite nice, I think. Currently about 50% of teh song files are hand-tweaked in the way they all will be by the end of this year or so -- the others are adjusted according to a less-accurate bit of automated guesswork.
...
Anyway, the 590's bring out everything they've been doing to improve their feed, and I've heard it every step of the way. It sounds pretty damned good now, but he'd like me to A/B and critique his newer 320k AAC stream against the 192k stream I've been using, but I don't use Android or iOS. If you do, maybe you should check it out: http://stream-tx3.radioparadise.com/aac-320 and see if you can run it through the speakers. Bill says it makes quite an audible difference.
Hope to see you back soon!
