To bounce fast, or REAL TIME!?

Probably a silly question, but...

Will I have more dependable results if I choose to bounce my projects in real-time? Is there a quality gain from being so patient? Something feels good about de-selecting "Fast Bounce", and letting Sonar takes its pretty little time with the mixdown, but I have no idea if it's to any real benefit.

I found out recently that an audio CD burned at slower speeds is actually better- more dependable, with fewer errors. I wonder if the same holds true with "Fast Bounce" vs. Real time.

Thanks!

-Alex

    No, you'll get the same quality. The only time you need to bounce in real-time is if a soft synth has a problem with fast bounce or if you are using outboard gear.

    In general, I agree with the other replies that the 'quality' will be the same.
     
    However, there are occasions when real-time bounce may not yield the same 'results'.
     
    This depends on the plugins ability to pump the data properly.  So if you do fast bounces, you'll want to do playback anyway to be sure.
     
    FX plugins may yield different "results", as one example.
     
    My approach is:  do real-time to insure what you're hearing is what will be the 'result' unless you're in a hurry.
     
    MOST plugins bounce fast without problems.  There are a few that do not do so well in fast bounce.
     
    But in general, I repeat, fast bounce is more than acceptable.

    only people witth too much time on their hands (and protools users) do realtime bouncing.
    i cant imagine the patience required.

    I fast bounce everything that I can.  But occasionally there are still plugins that cause problem on occasion.

    Ha, that's one way to look at it.
     
    When I do a "mixdown" in the project, I always do real-time because often I have found myself wanting to change something due to the mindset of "this is a mixdown" as opposed to a "bounce."
     
    I certainly don't have too much time on my hands, so I find your statement a bit self-serving;  but to each his own ;)

    Certain soft synths will clip using fast bounce . . . sometimes badly.

    For example, Steinberg's The Grand has trouble with fast bounce. I don't even mess with it. Every time that I use that soft synth I uncheck fast bounce.

    ba midi,

    just kidding, of course.  but if you are realtime bouncing and changing your mind, then you keep repeating the process, no?

    i just know that sometimes after ive spent six hours mixing songs for a client, i have NO INTEREST in hearing them again.  in some cases this would get me another hour of pay as we slowly bounce each song, but i prefer to be very time efficient in every aspect so long as quality is not sacrificed. 

    why do i suddenly feel like the only person who doesnt have any plugins that cant fast bounce?  is it really that common?  i have plenty of 3rd parties....

    I thought the only reason to real-time bounce was to earn more money if you are being paid by the hour.

    By the way chuckebaby, I can't get the metronome going but thanks anyways for the advice. I can't be bothered bumping that thread again!

    Well, see, I'm both for and against fast bouncing.  For it in general.  Against it when a plugin doesn't play well with it.

    Unlike you, after a long mixing session and being tired, I would want to listen again even more to double check myself - especially if it's for a client.

    But more important, perhaps, is the fact that some 3rd party plugins just don't bounce well in fast bounce mode.   Not many, though.    So I'd rather err to the side of caution.   The only way to know is to do a playback anyway - but whatever works is what matters.

    We each have our own work philosophy.

    I feel your pain! Such a frustrating thing to come across items missing in your mix because for some reason Sonar (or the gnomes inside my computer) decided to leave it out.

    I used to fast bounce everything until I ran across problems with *certain* soft synths which do the job better in real time.  By "better" I mean that in fast bounce mode, with these particular synths, notes would be skipped, sometimes whole sections.  In reaction to that problem, I'm now bouncing everything in real time, and even though it takes longer, the peace of mind I'm getting from knowing that truly "what I hear is what I get," I'm gladly giving up the convenience of fast bouncing.  It's like a couple more minutes in my life--my music is worth the time spent.

    The only time I have to do a real time bounce is whenever I've got raw BFD2 tracks in my mix, or more than about a dozen or so EWQLSO tracks.

    But I agree with Randy that the peace of mind from doing a RT bounce is well worth it.

    Don't know about x1 - but in 8.53, tracks with side-chained fx have to be bounced real time.

    You're in an amazing state.

    So stay there.

    Re:To bounce fast, or REAL TIME!? 2011/03/18 12:12:16 (permalink)
    Here are the arguments in favor of Fast Bounce as I see them:

    1. There is no quality difference between fast and real-time bounce unless a plug has problems.

    2. If a plug has problems, it will be generally be quite obvious - not so subtle you would miss it on playback.

    3. Disk-streaming VSTis are the most likely to have trouble; the vast majority of synths and FX do fine.

    4. Real-time bounce can actually be more prone to problems if your buffer is small, because SONAR is having to manage real-time audio streaming as it is rendering audio and writing the file. Fast bounce removes this burden, allowing SONAR to perform DSP and mixing more efficiently without the constraints imposed by having to keep your audio interface satisfied.

    5. SONAR has a longstanding bug that MIDI automation is not processed during a real-time bounce. If you want to real-time bounce the final mix, you must first freeze or fast bounce any tracks that use MIDI automation. I haven't checked, but I'm betting this issue persists in X1a, since not many carryover bugs from 8.5.3 have been fixed.

    You should bounce at realtime for final bounce down, and fast bounce when you just want to hear your mix for evaluation purposes.

    i bounced down to mp3 today i tried a real time bounce and it was awful...cracks,pops..even time stretched....i didnt listen to the final product..i stopped it half way through ....so for exsperiment purposes i did a fast bounce..no problem at all..the quality was great on the final product

    This is not correct as has already been indicated. Unless there is some obvious issue with fast-bounce due to a particular plugin, the sound quality will be exactly identical to real-time bounce.

    Randy, the missing notes problem during a fast bounce can probably be fixed by increasing the BounceBufSizeMsec variable in aud.ini.


    All else is in doubt, so this is the truth I cling to.

    i am really amazed by this thread.   its making me think.
    in over ten years i have never once done a realtime bounce.

    am i missing out on something????

    i had to think back-  there were a few times when something didnt bounce correctly.  in every case, trying it again or freezing a synth fixed the issue.

    when i fast bounce a track, i am done mixing it for the time being.  i have done my finals listen thru.    at least thats been my practice since pro audio 8.

    a friend and sonar user recently built a protools system at home and was dismayed to find that there was no fast bounce feature.  this has annoyed him.

    i just never would have guessed that so many prefer live bounce.  it has caused me to think.  and this can be dangerous.

    I was going to mention this as a particularly obvious example of how the constraint of real-time audio streaming can cause problems with bouncing. The process of MP3 encoding is not compatible with small buffers. If you increase your buffer size to something over 512 samples, you should be able to get a clean real-time bounce to MP3, but it's easier and more reliable to just fast bounce it.
