Clipping Converters

I agree with LSD. Crap converters will sound shit when you push them hard... but if you insist, here is a "tutorial" of what you need to do:

1: get your mix bounced to a (or dual mono) stereo file.
2: import back into your sequencer.
3: Creat a new stereo track and select the output of the track into one of your audio interface's stereo outputs.
4: plug that output into some hardware that has a VCA amp (volume knob/gain - such as a compressor, preamp, eq, whatever,).
5: Connect the device output into a stereo input on your sound card (so goes back into your sequencer)
6: create a new stereo track in your sequencer and assign the inputs to the output of your external device.
7: arm the track and press play - you have a loop (OP -->DEVICE-->IP).
8: crank up the device output (or your mixes track level). You meters will go to red when pushed (clip). If you crank it too much your converters will start to distort and it will sound like arse.
9: Push gain to taste and record in...

That's it.

Now (disclaimer):

1: cheap converters have less headroom, so they will distort easily not letting you getting your mix as loud as your limiter will.

2: some converters actually distort nicely (but generally those which cost a lot of money)

3: cheap converters sound bad when pushed.

4: You will need to use a brick-wall limiter in the end anyway, because if the level goes over 0, it will distort and sound horrible through consumer products (which have crappy D/A's built in).

5: if you do not have excellent monitoring, I recommend NOT to do this.

6: Experiment, A/B to your current limiter.

7: Bear in mind that every process on a waveform is DEGRADING.

8: Good luck frying up your weeks of work :)


I have mastered a lot of records and sometimes, clipping my Lavry's does the trick (although I do this through a combination of gain stages through my analogue rig), sometimes thing like the L1, L2, do the trick, sometimes tape does the trick... it's all down to everything in the recording process, starting from the song arrangement (believe it o not) and the performance.
 
Yeah I didnt think the fireface was not capable of this. Can someone explain how to do this? A quick tutorial

If you have analogue inputs in a computer sound card, it means they have Analogue to Digital (A/D) converters (same goes for analogue outputs)... they convert voltage into ones and zeroes so your computer can turn everything into maths.
 
I've got a hardware insert on my twobus.
that way you can use your outboardgear in cubase like any vst plug.
so when/if I'm clipping the converter (not doing that very often tbh and if so only in mastering of course, never in mixdown!) I just have the C2 on the 2bus, limiting the very peaks just a tiny bit (so the needle doesn't even move) and boosting the output of the C2 into the apogee.

I f I find the time I could perhaps make a short comparison clip of softclip on/off one the converter.
 
k, here's a little comparison:

no processing (so you can compare using your own limiter/clipper

Apogee Softclip off

Apogee Softclip on

for the records:
(you can perhaps hear how it's getting quite mushy already)
this is WAY more clipping than I'd usually use!
(at least in this one stage....this is about 6 dB of gain increase...usually I'd just chop a dB or two...than another 4-5dB in the finalizer (again in two seperate stages like 2-3dB each).
than perhaps another dB (if that) with a limiter

my average mixes have like -17/-18dB rms....in the mastering I'm aiming for around -10dB for the loud parts
 
Can someone please expain this. How can you clip digitally? 0dBFS is max so how is this possible?
 
I know my convertors are crap, but i couldn't hear a huge difference between the clipped and soft clipped clips. The unprocessed one left the snare "intact", but i like how the snare sounds after the clipping; it almost sounds punchy or harder.

it's pretty simple...imagine that 0dbfs is really a huge turbine fan that's spinning above your head at thousands of RPM's

now you add a bunch of analog gain to a signal in order to push it up to, and beyond, 0dbfs...but oops! your signal hits the turbines and gets lopped off instantly. if you only push it a little bit you'll still be ok...cram it too hard, and everything's going to be mangled.

Lasse, are you clipping prior to going into the Finalizer?

I have a Finalizer that I run SPDIF through my interface.

Could I set it up to get the output of the interface into the Finalizer via SPDIF and then run analog outs into the front end of my interface and clip there (by increasing gain)? I don't think you can go digital in/analog out, though...

I may have to do analog outs of the interface into the Finalizer and then into interface's ins, but that's another step of conversion...
 
Yeah, this is the Sterling Sound slam technique. I do ti all the time with Mytek 8x96 converters, sounds awesome. Best way to get things loud. I usually only hit the L2 for an extra 2 db or so at the very end. The guy next door did it with his Pro Tools 192 converters and I thought it sounded dull and mushy though. If you have sick converters, its a great way to get loud and clean for metal. But if you have crap converters, just go for the smooth and clean all digital mastering. If you really want clean and loud, you need the sick all analog pro mastering path. But plug ins are sweet, you just have to keep the mix a little quieter. No problem, why push it.?

If I could track down a 48k Crane Song HEDD I would be set... Those things are good, and about 1/4 the price of the newer versions, but they are VERY hard to find. I've only seen one surface on eBay since the beginning of the year.
 
Aaron, I don't think there was a 48k version, I think it was 96k - but I could be wrong.

Also bear in mind that technology has improved since then. You can pick up Prism Sound AD2's for like 500 u.s. They're 20 bit 48K (I think). I'm sure they sound great, but the newer reincarnations are probably better.

Yeah, those things sound great, I would not mind one myself (got Lavry's here).
