|UPD: tom 7 albums-a-day
(05 May 2003 at 22:25)
| I'm starting to move my old albums from their previous home at mp3.com (where you can now only have 3 songs) to my own web server in my office. I've uploaded #13 Examine Machines and Enrich (not previously available!) and #12 Image Gap Committee. More soon, plus new updated AAD homepage...|
|When comes new(er) Maigin Blank AAD?
Ooo, how crazy! I just looked at your AAD-12 page and said to myself, "Crazy! Tom took the photo I patched up and put in the DFX bio and used that for his AAD-12 album cover!" But then I looked again and said, "Wait a minute, those are only Tom lips, no Marc lips. In fact, this is a different picture altogether." And then I realized, "Whoa, that's weird, we both had the same photo collage idea, totally independently!" (Mine was actually inspired by a Yeah Yeah Yeahs record cover.) Freekee...
|Yeah, the AAD-12 cover predates Super Lips FX by several months. I had the same reaction, in milder form, when I saw that image.
I'll try to up Maigin's albums when I do the AAD page overhaul. What's a real easy way to do clip restoration?
Also, we still need mixes of Marm & Toc Album-a-Day #3... ;)
|Not to mention the very first one, Spastic Moose - Then Come The Chunks...|
|True, it would be good to have mixes of that too. I like that one.|
|Ahhh, what is going on?!? Now I am getting bugged to mix our albums not only by Tom, but by people who I don't even know? Oh no, now I need to come up with more excuses... Well actually, I now have fewer excuses. For a while, I had two main technical excuses: 1) my speakers are going kaput and 2) I don't have the Waves plugins in Mac OS X yet. I did a sly trade for new speakers a few months ago, and as of a week ago, I now have the Waves AU plugins for OS X, so now I have no more technical excuses, so maybe I will actually do those tasks soon...
Tom: Regarding clip restoration, I have always had good results with CoolEdit. First you convert your audio file to 32-bit (you need the float range). Then restore clips with no gain change. Then hard clip with 0 dB max. Then convert back to whatever bit depth you started at. If you need more specific step by step instructions, I can go actually check and write down the steps for you. Clip restoration in CoolEdit is one of the main reasons why I still keep my Windows emulator around.
Waves have a clip restoration plugin in their Restoration Pack, but I haven't tried it yet. Their other stuff is all super high quality, so it may in fact be very good (I simply haven't had to do any clip restoration for a while, so I haven't tried it yet).
|Marc: I'm the Arthur with 4 albums in the Album a Day list... not that you actually know me now, but it's a start. :-)
Oh, and I didn't mean to bug you, ok?
|OK. I will try CoolEdit. Is that shit free?|
|No, it's $69. See for more info on http://www.syntrillium.com/cooledit/
You can get a 30 day trial version though.
|Tuuur: Oh, it's no problem to bug me, I need it. ;) My reaction was really just surprise-that-someone-other-than-Tom-cared.
Regarding CoolEdit, it actually might be the "Pro" version that has those features and not the other version (I'm not sure, though), and that one is 250 smackers. But probably with a demo, too...
|Marc: ever since I'm aware of the AAD project, I'm curious about that elusive first conscious Album a Day that started it all... ;)|
|I wonder how hard it would be to write a clip restoration plugin? I suppose all you need to do is find clipping, then interpolate the waveform around it.
(And then DESTROY !!!!!!)
|I bet it wouldn't be too hard to write a clip restoration plugin. I, too, have considered doing one. I one main challenge, though, which is that, ideally, it would be offline, because the processing requires some lookahead, and the amount of ideal lookahead time is variable (depending on what the input signal looks like). But I guess you could do your best in realtime with a fixed lookahead. I guess you could assume that any clipping wouldn't last more than 1/2 of a waveform cycle, and that the longest possible waveform cycle would be 20 or 30 Hz, meaning (for 20 Hz) 25 ms for a half waveform cycle (and maybe more required for leadtime or whatever you need). I think that getting the hard limiting, after restoring the peaks out of range, to sound good is also very difficult and there's all kinds of DSP research and knowledge out there for making dynamics processing sound good, but personally I would just leave that stage out of the plugin since the output of AU/VST/etc. plugins is 32-bit anyway, you could just follow it with a limiter plugin, since there are already limiter plugins that do their thing very well, and I for one have no interest in learning how to make a limiter that sounds as good as the Waves L1, for example.|
|Right, there are a bunch of good limiter plugins so I was thinking of just letting the signal creep up past 1.0. That also gives you flexibility to just "turn down" the signal afterwards instead of limiting it.
|Oh yeah right, of course, turning it down is an option, too, I forgetted about that...|
|"forgetted".... is that on porpoise? :)|
|Oops, of course I meant "forgotted"...|
