Overloading on purpose

Discussion in 'Recording' started by ineedtolearnhowtorecord, Nov 15, 2008.

  1. HI there,
    I record at 24/96

    1) Sometimes wile tracking I overload the mic pres in purpose to get a distorted sound.
    Can this technique damage the mic pres or interface converters?

    2)Of course when I do that I can see the red clipping in protools, and the audio track clearly don't' fit inside the space anymore, however I can't hear any digital distortion jet!
    I'm damaging the converter when I do this?
    How far I can go after the red clip before digital distortion ? There is a different view option in protools that visually show how much is really left before digital distortion?

    You aren't going to hurt the pres or converters just by putting in a standard level signal and cranking the volume.

    Unfortunately, if you are talking about the preamps in your PT unit, I don't think there is any way to overdrive the analog portion of the circuit without clipping the digital signal. Overdriving a tube circuit, a solid state circuit, and a digital circuit all sound very different. If you like the sound of the overdriven digital signal...well...it's your song and you won't damage the equipment...and I guess the signal will look like the output of a lot of mastering houses these days.
     
  3. Thanks BobRogers,
    I have real preamps connected with patch cable to the interface/coverters, I'm cranking the gain of the preamps, and I don't have compression like mastering houses

    If I crank the preamps, the level in protools is clipping (red) and the track looks almost black

    How can I expand the track and axially see ?

    I guess the converters/protools, can handle much more dynamic than my analog preamps because I'm not able to hear any digital distortion jet!
    I'm blind because I don't know how to expand the track and see what's going on!

    If you see the red clip light in Pro-Tools, then you are digitaly clipping. If you train your ears you should be able to hear it. The vertical zoom is on the upper left bar above the zoom buttons. RTM there is a lot of good stuff in there... Like the answer to both of your questions.

    Don't worry

    The individual tracks is protools can clip and not cause unwanted distortion. As long as the master channels are not clipping you can push the other lines in the red. The main reason for this as I understand it is the way digital fills in gaps in recording rates. Google Dither and read up a bit. I am not sure I understand it enough to teach it.,

    Don't push it...

    The clipping from the original track is transposed into the master, it just happens within the waveform not on the extremities. However, when you sum a clipped track with another track, that isn't clipping, the flats will resolve into curves because of how the second track phases into the oringinal. If this all happens within the headroom of the master bus then you can win. But be aware that if you push it it will sound nasty.

    Also, regarding the thread title, caps are annoying and change "in" to "on". It hurts my sensibilities.

    All this pandering to people who find certain words offensive...

    Re: Don't worry

    If we were talking about playback you would be right, but the OP is talking about red clip indicators durring recording.

    i want to hear that jet also.
     
  10. OK I hope now the title is better.
    P.S.
    YET or YEt or jeT?
    But I want to train my self to digital distortion because I can't hear that

    Digital flat lines. You can't hear nothing. Or can you?
     
  12. Re: Don't worry

    OK , I'm cranking the analog preamps in recording mode , watching protools red clip, wile I set levels, before the recording too.

    I can try that , but I need to disconnect the preamp, why?

    Why are you doing that?

    It makes it much harder to mix down, you are stuck with the volume you've created.
    I can understand driving an analog pre hard, but I don't get why you want to feed your converters so hot.
     
  14. No, I don't do that, I just crank the analog preamps, it just happen as a consequence of cranking the pres

    I don't mix at all, I just record the tracks, that eventually will be mixed in analog.
    I'm using protools just like a tape recorder, no editing.

    so ...a red clip is digital distortion? how much headroom I have in the individual track before audible digital distortion, how can I see expand the track and see really what's going on?

    Read the manual.


    Yes indeed... Why?

    Why would you spend nearly $300 on software to record like a tape recorder? You can do that for free with Audacity?
    Yes. None. RTM or read my first answer.
