Quicktime audio quality
This is got to be a basic question, but I have never noticed any difference in the timeline audio and the audio that Quicktime produces (at least I don’t so). I’m working on a live music event, and I have done a lot of post EQ’ ing of all the music. Unfortunately, I was not able to plug-in to the soundboard.
But today, I produced a full Quicktime file resolution to check quality, and on playback, the audio seems to get a little distorted on a couple of songs when they hit the the louder segments. Not a lot of distortion, just enough to notice if your listening for it.
But when played back through the timeline, there is no distortion. Actually, I take back what I said: I do believe I can hear a better quality sound from the timeline-as opposed to the audio file that Quicktime produces.
I always click on produce Quicktime>use current settings. The audio rate is 48kHz and the bit depth is 16. Should the bit depth be set higher in the time line? Sorry, my audio knowledge is limited. But studying as much as I can about it.
Thanks!Jonny Cates

Where are the peaks hitting in the VU meter? You should never go above -6db.

Well Shane…after checking what you recommended, I think that was part of the problem. I made some adjustments there, with some improvement. I guess I should pay more exact attention to the meter, rather than relying on my ears to find negative issues.
However, I could also have a separate issue. I came across some technical audio information talking about what was called “rounding.” I’m not certain exactly what that means, but apparently the more math that is performed on an audio clip (using FCP EQ filters) odd things eventually start to happen to the audio. I interpret this due to the math involved and how software works. Does this make sense?
I had just never some across the term “rounding.”The more I experiment on a particular clip (trying to improve live recorded music) odd things eventually start to happen with the sound. If I totally remove any audio filters at one given point, then render the audio without any filters, I can then clear the sound oddities up.
I have a intel mac with plenty of power and mem, so I don’t think it related to underpowered hardware.Thanks for your reply…
