export is different to track!

Hi all,

I'm mixing an acoustic artist on Tracktion, and I am using the Waves L1, T-racks compressors/eq and Blue Tubes Brickwall.

The problem is this: when I'm monitoring it in tracktion it sounds a bit lifeless and dull, but there is no distortion. When I bounce to a wav file, it sounds much brighter and more natural and clearer (and slightly louder), but I'm getting some slight distortion in the vocals. The difference in sound between the monitoring and the bounce is sigificant, and I don't know why.

64 bit math is enabled. I'm monitoring on Tannoy Reveal Actives through a Tascam US-122.

Any suggestions?
Cheers,
Chris.

have you set your export settings to "normalise"?

thats the only thing i have noticed make a difference to the exported file?

also try exporting at 1x that should fix whatever is causing the distortion

Good luck

also, is your main volume slider turned down (not at 0)

Removing normalisation appears to remove the distortion; I thought that normalisation was supposed to prevent distortion, not cause it! what does this say about my signal? that's its got peaking transients?

i think also rendering at faster than 1x speed confuses the compressors; at a guess...

IIRC the waves stuff can be troublesome ... do a quick search here for it (never paid that much attention myself since i dont have them) ...

OK I've found the best sound is to be had with normalisation turned off and the render at 1x speed turned on. But, it still sounds very tonally different from the mixdown. Maybe windows media player adds its own processing?

ive found this as to be true. render does sound damned different. its tough if you mix things down for a 2nd job.

Do you have any suggestions for as how to fix it? is this a problem affecting tracktion or sequencers in general; in my opinion this is a very very serious problem and half negates the purpose of me investing in expensive monitors...

what bitrate do you render to?

when you say "very" what do you actually mean? Are we talking shifts in quality of low level audio (reverb tails and release periods), or full tonal differnces?

The former could easily be the result of either changing the bitdepth between 32/24/16bit, or appliued dithering.

The second case would generally be caused by altering the bitrate (as Ron suggests). Many filters simply sound different when working at 44.1, 48, 88.2, and 96KHz. This in turn means that anything that has built in filters (multiband comrpessors, instruments, and even delay/reverbs) can sound surprisingly different when rendered at different rates. Generally the effect shouldn't be enough to break a mix, and though it may be noticeable to you, your audience, not being familiar with the alternative, will never no or care. With a few filter designs the effect can be pronouced enough to actually alter cut-off behaviour significantly.

Personally I always compare plugs at 44 and 88k, and if there is a large enough difference I simply quit using the plug, 'cos I consider this a bug.

dose the phazing sound different?

if yes then it could be a pdc render bug

to the untrained ere it could just sound thinner & more loose

could you list the plugins you use & if you use bussing in your edits? (EG; send tracks to another track)

also if you import a normal wav file & export that to a wav file dose it have the same difference?

I was rendering to 16bit 44khz, for cd burning. i've kept tracktion's iternal bitrate to be 44khz as well. The difference sonically comes across firstly in terms of EQ; the exported mix is definately brighter and more transient heavy. It sounds clearer. The difference is, while not horrific, certainly noticeable even to the lay ear. I would possibly suggest that the exported mix has different compression to my tracktion mix; probably due to t-racks messing around.

I am going to be investing in a presonus firepod in the forthcoming weeks; this will let me try to monitor at higher depths/rates. I hope that will help.

the reason behind you problem is that you're using Tracktion!
Rule of thumb: don't render in Tracktion if you don't like the unexpected!







:hihi:

Have you imported the mixdown back into traktion? Maybe the differance is in media player?.....just a thought.
