I listened to your AAC 96 stream and you have something to be proud of there as well!
Thank you for the kind words; I keep tweaking away at it.
I remember in 1989 hearing a local AM using a 3-band "David" processor, I think it was called? (an Inovonics product, anyway) on the TX11a and being absolutely blown away at how open, rich and clean the sound was... the local FMs sounded constipated next to this little AM stereo station (KXTD-AM 1530, Wagoner, OK).
Certainly the differences in processors and how they are set make a huge difference in the sound; I'll never argue AM sounds better than FM... OK, I will on a bad night when I feeling particularly crotchety... but when reason is in my head, there's just something about cleanly reproduced amplitude modulation which, even with the potential noise interference, does something nice to sound waves.
I suspect it is partially the "tube amplifier" effect: audiophiles swear by tube amps vs. solid state, techs run the specs and discover the tubs are adding pleasing distortion to the original signal. 8)
WION doesn't sound quite as crisp as I remember KXTD sounding (long since sold, all equipment changed out, and different programming today), but I wonder if KXTD was using the NRSC curve at the time... not sure it was mandatory yet... someone else will remember better than I do. WION is also processed less aggressively than KXTD was (even with their simple box)... WION exchanges KXTD's "punch" for openness and depth... which works for me.
There is a partial truth that is the basis for the original "process web streams independently," and that is that the lower the density and the less peak clipping performed, the better time the data compression codec (mp3, AAC+, etc.) will have deciding what to keep and throw away... in other words, it will sound better.
Consider that most FM stations are compressing the SNOT out of their programming, and you can see why plugging the output of an FM tuner into a sound card and encoding it might give less than ideal results...
...but how about FM radio stations stop FREAKING OUT about being the loudest thing on the dial and process for fidelity? Then they will have a great on-air signal (with no loss in coverage since density = coverage only applies to AM), and it will double as a quality web stream, too.
Yeah, I know: keep dreaming... :
The density vs. fidelity issue is one of the things I struggle with on my little web stream. Here I am, trying to duplicate the sound of the hot-rockin', flame-throwin' top 40s of the 1980s, and many of them created a "wall of noise." I aim more for the track-to-track consistency and limited fade-outs than actually getting the kind of density you'd see from a couple of Audio Prizims in front of an 8100A with an XT/2 limiter chassis, all set for "blowtorch."
Most stations today (I believe, based on listening) don't use a ton of AGC but deeply limit and clip for most of their density. The result is programming that doesn't pump and breathe, but is razor-flat across the top... very loud, and fatiguing to my ears.
Stations in the 80s were more likely to use TONS of AGC, resulting in "coloring" of the recordings in some pretty unique ways. You'd hear the record and find this isolated hand-clap or that isolated guitar lick wasn't NEARLY as loud on the record as it was in the recording... the compressors had sucked it all up.
It was an extension of what had been done in the 60s and 70s, just with new tools: in the 60s, AM stations used singleband compression to create maximum coverage and the result was an exciting (some would say fatiguing) sound. Multiband compression came out in the 70s, and suddenly stations could run more compression with less obviousness and also end up with more consistent eq and "texture" from song to song and source to source.
One of the things I do is run the attacks just as slow as I feel I can get away with... in some bands, attacks are as high as 75 milliseconds. Why? Analog processors couldn't react instantly to peaks without clipping the way today's digital boxes can. That "sloppiness" (hopefully) helps re-create the sound of the analog 80s radio station.
A fantastic side-effect is that the songs that have had all the life beaten out of them by the local digitally-processed AC suddenly sound alive and punchy again!
Anyway, I'm rambling... thanks for the kind words, and I hope many people take a listen to WION's audio stream to hear how good both AM and web streams can sound!!
