Maybe the undiscerning audio book listener won’t notice the hum?! …
They may not. But ACX will. Or the Robot will get there before human Quality Control.
We simulated what the robot is going to do with Will’s compilation testing tool called ACX Check (if I haven’t mentioned that already). It’s a plugin that appears under Analyze.
That may be the older one. The newer one is prettier, but says the same things. I gotta fix that one of these days.
ACX has a very simple weed-out process that catches ratty submissions. When you’re speaking, your peak sound values have to stay below -3dB, your volume or loudness has to be between -18dB and -23dB, and when you stop talking, what’s left (the background noise or Room Tone) has to settle below -60. If you do a very good quality job of announcing, you can crank out one of these compliant clips without a big deal, or your clip can be made complaint with a simple volume change. I, my very self, have done this, so I know it can be done. It’s not fantasy and it also happens to be broadcast standard.
Then it’s on to the human Quality Control. If you got past the Robot by applying legions of filters, effects, patches, modifications, and changes, you will most likely fail QC with “Excessive Processing” (he said, gazing up at the above thread’s list of notches and filters).
Without knowing any more about your setup than the amount of corrections it appears to require, I would think about changing it.
You can achieve the -3 thing with Normalize. I use -3.2 instead of -3 for safety. Conversion to MP3 later can mess with this setting.
– Select the whole clip or show by clicking just above MUTE.
– Effect > Normalize: [X]Remove DC, [X]Normalize to -3.2 > OK
Then Analyze > ACX Check and see what it says.
