Audio Peaking out!

garo wrote on 3/7/2005, 10:45 PM

All too often my audio tracks peak out after rendering - in the Mixer window I can see them hitting up into the yellow and red regions - this can pertain to actual Sony Loops or other sound tracks - they sound great in Vegas Preview mode and while editing but are totally ugly when rendered out. A good exapmle is my entry in the vasst contest = Tropical Goat Island -
Of course i can pull the audio level down with the appropriate slider control but the Sony Lops shouldn't need this some I thinking that it is another issue.

THanks, Garo

Are you applying any Eq ? Eq FXs introduce a small amount of gain at the cutoff frequency so you only see the result whne there's something at the same frequency. This used to cause me the odd over that was hard to see until after I rendered it out. If you've got SF it's easy to check for overs one you've rendered the audio out.

And you only have one track of audio?
No crossfades although that's unlike to be a problem.
Don't have any panning going on, panning a track hard to one side lifts the level 6dB.
Track and bus gain all at 0dB?
No envelopes?

Easiest way to check all this is replace something with a 0dBFS IKHz tone.
It should stay that way all the way thruough the process. It's much easier to see what's going on with a constant, known level.

I set everything at -3 for the final mix/render. Beyond that I also use things like the Waves plugs - such as the L1/L2/L3 Ultramaximizers. As a rule of thumb you should really do a final mix by looking at the meters - if it is peaking a lot it does need to be brought down. Working in a digital world is not something you can do with just your ears...I am speaking about mixing "hot" like you could/can in analog. I have yet to hear anyone say they like the "nice warm tone of digital distortion". ;)
