In general, ACX Check is used as the last step before you create the MP3 sound file and publish to ACX. If your performance gets noisy at the end, then it doesn’t pass. Many home performers have trouble passing noise. It’s a pretty stiff requirement.
We publish an audiobook mastering suite of tools and it doesn’t use plain Normalize. Are you using a mastering process from somewhere else? Are you ad libbing?
A question. How do you know which side of the microphone is the front? Which side to speak into? I downloaded the user manual and they have a paragraph about how important announcing into the front is … and then don’t tell me which side is the front.
That and at least one supplier has the lead graphic on their microphone promotion that I’m pretty sure is the back. There is no detail picture of the front.
As a fuzzy rule, the side you announce into has the company name. Were your instructions any clearer?
You can have some very serious sound problems including noise if you get this wrong.
My recordings pass the ACX check but there is a lot of background noise that does not show up until I “normalize” at the very end.
Normalization is simply an up-or-down volume change and the noise will go up or down along with the signal (the signal-to-noise ratio doesn’t change). i.e. If normalization boosts the volume by +3dB, the peaks, RMS, and noise level all increase by +3dB and just like turning-up the volume control it makes the noise more noticeable.
Hi, you are right! I had changed that as I was pulling my hair out trying everything…I have changed it back.
I am not sure what voodoo you have done but it all sounds great now, the constant “chchchchchch” has disappeared.
The biggest change I made was to change what was covering my table - for some reason I had a very fluffy blanket and I covered that with a sheet had I don’t know if I am imagining it but that seems to have made the difference.
I am not sure if you had any other ideas, I am always open to suggestions to make it better,
Send some of it to the forum. Identify it. “After the words at 3 seconds,” for example. It’s not shocking if your speaker or headphone system is making up its own noises and your voice is actually fine. Are you using wireless earbuds? That’s not the best idea.
I have to learn how to speak correctly to optimize it.
The makers of home microphones would like you to set up in the kitchen, record many successful audiobooks and retire to a picturesque cottage on the French Mal de Mer coast. It’s more involved than that.
Most of your P-Popping and breath noises go straight forward and down, so yes, a hanging or “non-desk” microphone can help.
If you’re using a pop and blast filter (black tennis racket), you should be about a power fist away.
If you have aggressive popping (the tennis racket isn’t perfect) you might try moving the microphone sideways.
If you move it more than about the B position, your voice will start sounding muffled.
Every time you make a change, you should record a test and see where the blue waves settle.
It’s possible you never get the right volume and other corrections may be needed. Home readers never pass noise. I have a really quiet bedroom and I still have to wait for the Metrobus to go by.
