It occurs to me to ask, did you already read the whole book? That's a common New User error. Read the whole book with technical problems and only then check if the work is OK. If you hit particularly evil errors, you get to read it all again.

This has been so helpful, thank you thank you.
That's not straight mastering. I had to add Mosquito Killer 4, Noise Reduction and De-Essing.

Kozikowski, could you walk me through the exact steps you used for Mosquito Killer 4, Noise Reduction, and De-Essing? Are there specific specs or can I just run them? I already had the Equalization/RMS/Limiter specs running as per ACX requirements and also use ACX check. It had passed with the whining, though I knew it needed fixing.

Yes, this is exactly how I would like to continue, and I'll just re-record one day of work. You guys were right about the in computer recording. Are these the best steps to take for future audiobooks?

This is my current setup:

Also! Do you recommend applying plug ins before or after manually removing breaths with room tone? This is the only other editing I have been doing besides plug ins. Are all my bases covered?

No, I've only recorded the first 15 of Essential Oils. As for the children's book, it's only 14 minutes long so re-recording isn't a problem.

I can do all those things, but you caught me one foot out the door.

Soon to be followed by the other one.

When you quote someone, select it and click the fat quote marks above the forum text panel. I patched one quote so you can see what it looks like.

As we go.

Just figured that out too, thanks :) Okay fantastic, what I'll do now is re-record the audio and then edit and master it later tonight when I get back from a job, so any other advice you have, when you get a chance, would be really appreciated!

Overall Room Tone is quieter post mastering, so you may find it easier to hide breaths and other mouth noises.

I think I'm making some unwarranted assumptions. I picked Oils with Noise from your Dropbox example postings as "raw" and with no processing. That's not true, is it? I started to dig and discovered signatures from some of the effects.

~~

How I did it.

Effect > Mosquito-Killer4 > 8 mosquitos > OK.

Mastering 4 just as it is.

viewtopic.php?f=64&t=96103

Effect > Noise Reduction.

Right there we run into the first problem. Your Dropbox-1 posting has two different room tones. One fake which makes me think you made it and stuck it on the beginning. The real, higher room tone with the whine in it only starts about a half-second before your first word.

Quiet Quiet Quiet Quiet FFFFFFFFFFF "Copyright 2018..."

That's dangerous because ACX Check has terrible accuracy if you don't give it at least a half-second of "real life" room tone, and it's not accurate at all if you have all that "fake" silence. ACX Check uses the quietest half-second it can find. ACX Human Quality Control (not the robot) is going to catch that noise level shift pretty quickly.

So I cut off all the fake silence and extended the louder room tone (copy/paste).

Yes, it does pass, but just barely. 62dB out of 60dB limit

Drag-select a chunk of that new room tone noise. Effect > Noise Reduction > Profile.
Select the whole track by clicking just right of the up arrow.

Image

Effect > Noise Reduction > 6, 6, 6 > OK.

That's technically not needed, but it sound better because the shshshshsh sound between words is quieter.

Then it's up to you. Listen critically before and after applying Effect > DeEsser at the default values.

You're listening for overly crisp and harsh SS sounds. My joke is the "ice pick in the ear" sound, to be avoided. Microphone makers think that sound makes it more "professional." It doesn't.


I see your studio. You're much further along than normal New Users. That explains why I was missing some of the errors when I listened the first time.

Is there inside padding on the top , bottom and back? Is the microphone sitting on the table? You may still need that towel and book thing. Anything that fits. Half size from the illustration. If you don't do that, I bet every time you rap on the table it gets into the show. Or worse, somebody in the apartment downstairs.

One oddity outside the box. Don't put a plain wall straight behind you. The sensitive part of the microphone is towards your face and the wall behind you. Perfect for picking up room noises. So your back should be pointed toward a wall at an angle or pointed at a corner. This is hard to write. Rotate the desk and your chair slightly so the microphone is not aiming straight at a wall if you weren't there. I have no idea what the rest of the room looks like.

Or your could soundproof the wall. Hang one of those furniture moving pads behind you. My personal favorite was the room at work with stacks of cardboard boxes. Perfect soundproofing.


Record a test rather than re-purposing an existing recording. 20 second mono WAV files will fit on the forum.

World's worst illustration. Top View. Microphone and box pointed at a wall. Doesn't have to be that extreme a tilt, but any angle other than straight-on is good.

To answer your questions several posts ago. I would say that yes you would be better off spending money on better kit vs on possible fixes for the mosquitoes with the current microphone. Folks seem to have better luck with separate USB interface with microphone inputs (there are a lot to choose from) and a separate XLR connected microphone (where again you have a ton of choices).

In the meantime if you can get work out the door using the mosquito killer plugins go for it.

Adding to what Koz was mentioning about not having the wall directly behind you. Be aware that Corners are even worse than a flat wall, because no matter the angle between you and the corner, any sound from you comes directly back to you. (google "corner reflector")

Hanging a moving blanket behind you works really well and can be easy to set up an knock down.
