    Here is a tech library at tc electronic

    In the Tech Library you will find Papers and Articles about Audio Fidelity and Processing published by TC Developers and other Industry Professionals.
    Note:
    The Tech Library is not TC device specific.

    The Tech Library is not TC device specific.

    but 90% of the engineers writing the papers are from Denmark or Norway and the rest from Germany :laugh_at:

    seriously though this is a very good thing – I’ve been meaning to share those exact papers, but EBU indexes them as obscure item numbers and they are mixed in with a bunch of other stuff, which is only of any use to those lucky(?) enough to be working with or for a multi channel major public broadcaster, but sinners link is all of them indexed in a easy to navigate fashion.

    to be fair Auntie have contributed to this project as well, but their tech papers contain page upon page of heavy maths which I was never that good at (a big reason why I dropped out of uni many years ago). They did even share a free loudness meter program, but it wasn’t immediately easy to install (looked like whoever did it normally used Linux and very begrudgingly knocked up a Windows version (in spite of most of the PC’s in the BBC outside the boffins’ labs being Windows)

    anyway, the end result was a ME12 emulation (the standard “British” analogue PPM) with a embarassing mens’ health problem. The amount of “droop” had something to do with the loudness (LKFS) value. I took one look at it, burst out laughing and thought “no fucking way is that going to be in my studio”. Hence why I use “eurometers” ( a LED-style PPM on EBU digital scale) from Darkwood (though the chap what wrote them is British) and the free Orban loudness meter.

    it also really is worth dedicating a separate PC to this is you are serious about producing music or online broadcasting. LCD monitors are cheap these days It can be a older second hand one – the Orban meter is a bit more resource intensive (it won’t run smoothly on the netbook) but the Darkwood ones run on many older machines.

    The soundcard need only be 44 Khz 16 bit with a line in input, doesn’t need to be pro audio as its only monitoring the sound

    you must of course line up the levels so that whatever meters on your DAW or DJ software (if they exist and/or show anything sensible) are showing the same on the other metering PC. beware that many LED displays on DJ mixers and other lower cost kit with in built USB cards show -dBFS on an analogue VU meter scale, and this is the level going to the input of the USB card (which you may well be using for broadcasting)

    This is worse than useless as it positively encourages users to clip the audio as they think the yellow (well over 0db) is OK to go into. if you have equipment like this and there is no easy way of adjusting the scale, simply ignore it – cover the LEDs with black insulating tape if necessary and use something else you know you can trust to check the levels.

    Ha! I worked in a tech library for a bit. Not audio mind you. Spent most of my time moving shelves around and updating technical publications. Quite dull ’twas. Good chairs though…

    If you are just going to be placed in there learning, there must not be a issue. If you want to examine something out, see if there is a lending contract between your association and theirs….i think this method is the best method to teach..
