Bouncing 24 Bit Vox Audios ... Degredation
(Note: I've been having problems with clip-envelopes choking/slowing down Sonar work-flow. So I'm hoping to bounce multiple times in order to work around the clip-envelope issue) 1) ... How many times before degredation gets noticeable (to your ears) per se? 3 ? 2) Melodyne bounces: 1 ? 3) Bouncing before/after Fx's are added: 3/1 ? 4) Bounces with clip-volume envelopes ? (Note: clip envelopes seem to choke Sonar a bit) 5) And/or ... please describe how often you confidently bounce your vox tracks, parameters, settings, etc. ... or other pearls perhaps. Any comments are welcome here. (You may include export bounces and other settings, like 16, 32, and/or 64 bit, etc. ... but I'm sort of assuming you bounce from 24bit to 24bit for the most part) Thank you for bouncing your ideas here!

bits are like brain cells to me. I try not to lose any. If you've already gone thru the agony of doing the clip envelopes, why worry about em? I don't bounce unless I have to. Melodyne, just import it. done. EQ, why bounce? But then again, I've thinking about the concept of committing to whatever I've done to a track and moving on just to get that one decision out of the way. Still in the thinking about it phase though.

When I bounce, I bounce one time only. But I do not see a reason to bounce your effects before mixing down (exporting). Also, bouncing to clip should not degrade your audio. My render bit depth is set to 32, as it should be and thats what it renders to when i bounce Cj

In the digital world, theoretically, you could bounce forever and the end result would be the same. However, when you add melodyne, eq, compression, and all the extra stuff, you will fundamentally change the resultant wave...and when you bounce, it is non-reversable. So... keep the original vox track safe somewhere then if you really do go too far, you can scrap it and start over. I will sometimes make 2 bounces..... melodyne and then on occasion, I will insert O4 to polish a vox track....and bounce it again to eliminate the FX in the project.... and since I don't like to have any CPU heavy FX running in the project, (except O4 in the master buss) I will bounce everything except the cake default FX in tracks.

Yea, 32 (or 64) is good as long as you stay in SONAR. Sound Forge does 32, don't know if it is up to 64 in the latest. Also, have the 64 bit render engine on (options>Audio>). It really shouldn't have much effect - doing multiple bounces, but I come from analog. And I used to have to do it on my old computer(s), too. Freeze (?) or Export/Bounce the clips/tracks w/ envelopes and plug them into tracks. You can even try the multiple take in a single track - just enable and record a split second to open up the extra track. Import and Q the original. Don't EQ or effects or send when you do it - one step at a time. Then export the whole (w/ sends/EQ/effects) as a regular file. One bounce, esp. at high bits, shouldn't effect teh sound. Tho I would check to see if it does bother you. @

I think the real question here is why Sonar misbehaves with you Clip Envelopes Philip. You have a VERY capable pc so this should not be happening. I rarely have to bounce anything - the last project I mixed consisted of 75 audio tracks, with multiple FX, Plugs, Busses, Live V-Vocal clips and extensive automation. Admittedly, I had to lower my latency quite a bit for the final mix, but once I'd done that, Sonar didn't even blink. Digital bouncing should cause NO audio degradation, even after multiple bounces - it's just numbers, not audio! Try playing around with your latency to see if this helps, or consider moving from Clip envs to Track envs.

You mean you lose quality in generations like audio??? I thought not.

Bristol_Jonesey, thanks for going the extra-mile with me on this. I've absorbed your latency suggestions thoroughly. This PC-DAW is powerful (Windows Experience Index = 76) ... ASIO (effective) latency is 1.5 msecs. I'll experiment with 'raising' and 'lowering' some more buffer size to see if it helps. Timidi and GuitarHacker: Thanks for your suggestions. Tidiness is also an issue. Judiciously bouncing vox/guitar tracks ... I'm hoping is a healthy thing ... when things get cluttered/choky. Now How, thank you for validating Bristol_Jonesey on this sensitive issue of quality after bouncing clips. AT and CJ: Right now I'm doing 24 bit. I ponder if the 8-bit difference is worth it to go to 32bit for that guaranteed extra-fidelity ... and working with Fx's, latency, and all. IOWs, I'd like to know if others are using 32-bit as the reasonable standard now?

32-bit as the reasonable standard now? Only for rendering as a floating point, not fixed point. No sound cards can record at 32bit as of now Cj

Philip, I'm not validating anyone...i'm asking: Can you lose quality by generation in digital????

I see, Philip is talking about more than just copying or duplicating, he's talking about manipulating it at each generation with some artifact....i wouldn't think that was 'degradation' so much as that it's actually responding to the manipulations and the result is that it has been manipulated.

Philip IOWs, I'd like to know if others are using 32-bit as the reasonable standard now? 24-bit clips with 32-bit floating bit rate.

Thanks Dlogan and CJ (again), NoHow, and Bristol ... for helping clear some clouds. (Note: Bristol, that gearslutz article is a bit long and sporadic, I'll just trust what you said)
