    I found a plugin for Audacity called ReplayGain. It seems to better handle the random loud “tick” without drastically affecting everything.

    ttps://wiki.hydrogenaud.io/index.php?title=ReplayGain

    Page doesn’t mention a word about Audacity. Is there a different download link for the plugin?

    I had a little bit of a chuckle regarding the transposed left and right channels, as I would have otherwise mistakenly assumed that in the modern world of digital audio, this should not happen.

    Well, Muzak’s stereo simulcast of “Jukebox Gold” on Echostar had the channels swapped for years, and probably still does for all I know (I haven’t airchecked it in well over a decade). Granted it’s not technically broadcast radio in the traditional sense, even though it’s produced using basically the same technology.

    I think that the request for -6dB normalization has to do with how the gain is set at various points in the airchain, and it is the modern equivalent of telling DJs to not allow the VU meters on the console to go over 0 dB. (R)unning the levels slightly on the hot side would cause the processing to engage more, if you will, so that there would be less audible difference between soft and loud passages. In effect, this would cause these volunteer stations, which are very likely trying to avoid the trappings of commercial radio and appeal to more serious music aficionados, to sound more like contemporary hit music stations.

    I believe that would be correct. Similar principles apply to analogue tape, where 0 VU is the theoretical “maximum” level that most common magnetic emulsions (i.e. ferrics) are able to record full dynamic range without going into saturation and clipping.

    Don’t use MP3 for any kind of music content to be broadcast on the air!

    There, finished your sentence for you.

    MPx are perfectly acceptable as general-purpose codecs for headphones listening or to be pumped directly into a PA amp/speaker chain from a playback device. I mean, the “big two” music services have used modeate-bitrate MP2 for years in their disk products, but they also have mostly or all-PCM production workflows and audio chains for their satellite broadcasts. They can get away with it. And in a lossy 70/40 mono PA chain in a noisy store or restaurant or a quiet office, when properly EQd and companded for the specific playback environment it’s mostly not noticeable anyways.

    Generational quality loss is inevitable in analogue-digital hybrid broadcast audio chains like all the other guys have touched on and since PCM is much more widely deployed (due to its age and ubiquity) than the much newer FLAC format, it’s the format that should be used for broadcast content.

    FLAC website, for those who don’t feel like redirecting through a Wikipedia page: https://xiph.org/flac/

    Most of the popular acrimony and discontent against the MPEG1 audio codecs, particularly in audiophool circles, comes from improperly encoded files (i.e. lower than 44100/320/stereo or 160/mono), usually by (deaf and dumb) people using the default settings which usually specifies a far-from-optimal psych model (RTFM!!!!!), or using suboptimal or outdated codecs (cough Itunes cough). That’s why there’s so much shitty MP3 audio floating around the Internetz today. The thing is, encoding using the highest bitrate/transform settings takes time. It’s the whole “instant gratification” stereotype. For most people it’s quicker and easier to generate a file that sounds like shit than to wait a few extra seconds (or minutes) and generate files that are indistinguishable from the original.

    It’s a notoriously easy format to totally screw up and do wrong, but it doesn’t have to be. When done right it can really sound great.

    Would be nice if he used a DNS service, though.

    No receivers in LA or New York City/Long Island! Probably the last places on earth I’d have expected to see that!

    Can’t say I have any first-hand experience with the eruption(s) since I was born 4 years and a month* or so after the first one.

    (* It was a rainy cold day in April, and the clocks were striking thirteen.)

    But, my uncle and I were replacing the siding on mother’s old house in Orchards ~15 years ago. When we pulled the old T111 away all this whitish powder started falling out of the wall. Turned out it was St. Helens ash that had been trapped in the wall for 2 1/2 decades prior, and there was a shit-ton of it on the house’s north side! That part of Clark County (not terribly far from Heritage Federal Correc…um, High School) wasn’t nearly as over-developed as it is today, so they got hammered.

    There was this nice whitish-gray outline of the house in the dirt for a few weeks until he put new bark chips down.

    … I have yet to find anybody who can figure out why that is. You get what you pay for in a tape, especially in performance and fidelity, but they expensive tapes really stiffed people in the “how-many-decades-will-it-hold-up” area.

    One big problem is acetate tapes. Vinegar syndrome tapes may be playable but can royally fuck up heads, path and deck electronics if the tape path isn’t thoroughly cleaned after each pass.

    Maybe if another major retailler like Target or Wallyworld, or shit, even Freddy’s zhwoops in and takes the place of one of the major department stores they might buy the mall a little time but I doubt any of those will.

    Van Mall has been floundering for a good 15 years now. Westfield was one of the worst things that happened to it and had probably its highest vacancy rate between 2003 and 2007. (I worked at the mall then.) Cheney & Co didn’t help, but Westfield’s constantly jacking rent up was the salt in the mall’s proverbial wound.

    I’m not surprised. They’ve been slowly circling the drain for years (along with most of the legacy department stores).

    After Penney’s, all that needs to happen is for Macy’s (Meier & Franks) to close. There’s an extremely high likelihood that AMCrap-O-Topia will file chapter 11 in the next few months so it’s doubtful that shithole excuse of a theatre will reopen, and once those three are gone that’s it. Vancouver Mall will fall flat on its ass. Old Navy, H & M, Men’s Warehouse and the gym (used to be Nordstrom’s) have lots of square footage but they’re not big enough to be considered major anchors that caould, in theory, hold up an entire dying mall.

    I really doubt it’d be your preamp causing the problem. (FWIW, I use a stereo receiver with the tape-out connected to the line-in of a sound card or an….. sorry.) I think we can safely narrow it down to two factors. (1) Their decoder doesn’t properly handle joint stereo (don’t shrug it off; I once had an APEX DVD machine with an earlier (crappier) firmware that made it put sum on the left channel and difference on the right) or (2) they’re downbitting when preparing the show for broadcast and playing the reduced bitrate file over the air.

    I’d probably bet on condition #2 these days. Probably some volunteer who doesn’t know what they’re doing, or doesn’t care, and is using the default bitrate (usually 128) and transform accuracy settings (usually medium) for the export. Not much you can do except beat them upside the head and ass with a rubber chicken, and rinse and repeat until they finally get a clue. I don’t even use 128 Kb except for mono material!

    Condition #1 was more common 15-20 years ago than now, when the MP3 format was just coming of age, but it’s surprising the amount of decrepit equipment decades past its prime there actually still is in the wild, in regular operation.

    He’s using Audacity for editing, which probably means he’s exporting using LAME since the one interfaces with the other directly. Current version of LAME is 3.100.

    What Andy_brown said. I assume you’re encoding at constant bitrate, discrete stereo (not joint stereo). They could be reencoding the final show at a lower bitrate, for whatever sick reason.

    If it were me then I’d lock everybody in the station and hold them at gun point until they finally pledged to stop doing that! 48/320 or Fight!

    FYI, -6dB is 50% peak (switch your output meter in Audacity to linear mode, generate a test tone, normalise it to -6 then hit play and you’ll see) which AFAIK is a fairly standard program level. SRL is -18 dB in digital audio systems which is equivalent to VU 0, or IIRC 250 nWb/m magnetic flux when measured across the head gap, but that’s tape. Presumably they want a little more headroom in case somebody’s program audio exceeds the station’s preferred peak level. That’s just my wild guess based on nothihg, anyways.

    Their stereo systems in the 70s were amazing.

    Actually they still are, at least until their aging transistors start flaking out and getting noisy.

    Amazing how you two can turn even a thread about failing and at-risk businesses into another pointless candidate-versus-candidate pissing match.

    It must be a talent you have.

    As for J.C. Penney yep they are next to go. My local mall still has Macy’s but once Penney leaves they likely will follow. These large spaces will have no choice but to be repurposed. How that works out is probably dependent on the local economy. But yes, malls are quickly going to be a thing of the past.

    Vancouver Mall?

    Nevertheless, VM is definitely hanging on by a very fine thread. They’ve been slowly converting to a “lifestyle center” (i.e. hipster millennial-friendly) business model since late in Westfield’s reign of terror. There are several construction projects currently in progress around and in the mall (the military were in the process of opening a huge-ass new recruiting station when the mall shut down) but who knows if it’ll survive when everything finally reopens next month. I’m wagering that it won’t survive past 2021 because of the very fact that malls are generally in their dying days, virus hysteria or not. Once Penney’s, and finally Macy’s/Meier & Franks are gone, Van Mall will finally EOL and collapse with nothing left to hold it up. The concept of centralised brick-and-mortar, one-size-fits-all specialty retail is simply not viable any more, both with social paranoia and private/convenient online shopping being what they are these days.

    As for the resulting grayfield’s future, who knows. I imagine they’d probably tear the mall down, rezone the campus and redevelop as yet another planned community of a shit-ton of apartments and McMansions (gotta warehouse all those Texaforegonian license plates somewhere).

    I can’t even get fibre since Centuryshit have stated they have no plans to pull cables into my neighborhood. Unless I were to develop a masochistic side that pushes me to live with the headaches and bleeding ulcers that come with dealling with Commiecast, I’m stuck paying for 15M/5M VDSL2 and getting 9.2M/896K on a good day. Closest thing I can hope for is fiber to the concentrator with a decrepit last-quarter-mile copper pair to the house.

    Rereading my earlier post, I am reminded of the late, great Andy Williams:

    “No! We will NEVER give you fiber! Not now, not ever, NEVER!”
