I did it with obsessively designed wooden sticks. That's one stick multiplied 28 times for a four-wall studio. They're symmetrical. It doesn't matter which way up.

One poster did it with plastic pipes from the Home Store. No glue, they just push together.

One caution with that. Light, airy and comfortable duvets/quilts don't make particularly good soundproofing. Heavy is good.
In the meantime if you can get work out the door using the mosquito killer plugins go for it.
Exactly. Do the short form stuff right away and save the long-form book (if possible) for better kit. I'm a believer in hanging on with white knuckles if you get something working.

If you do get better equipment, you may find the Mastering different. If you cast off the USB microphone, you won't need Mosquito-Killer any more. If you get rid of that background noise (the hiss, not the whine) you may not need quite as much Noise Reduction, etc.

Two makers have native mono, voice compliant interfaces. Behringer has the UM2 and the UMC22, and Focusrite has their Scarlett Solo.

The microphone is up to you. Asking about the microphone is like asking someone what kind of music they like. Get one of the interfaces first and then see if you can borrow a microphone. Do you know anybody in a band? Well enough to borrow a microphone?

You should know that although USB microphones are limited by the length of the USB cable (6', 2M) an XLR microphone cable can be extended to 75 feet, 100 feet or more. If you're not paying attention to the Audacity recording meters now, you can push the interface and computer out of the room.

Thank you all for the information. I'm going to apply all of this, and right this second, scramble to make the children's book hopefully check. I'll respond back in detail tomorrow!

Mastering 4 will always make a technically compliant sound clip except for noise. Noise is almost always traceable back to equipment or environment issues. The other tools are tinkering around the edges.

Again, I'm not entirely sure the integrity of the clip I've been inspecting. If you could shoot and post one of those 20 second tests that would be good.

It's not hard. Pause and be very still for 2 seconds and then read anything in your normal voice for 18 seconds. Export WAV (Microsoft) 16-bit and post it. Do Not apply any filters, effects or corrections.

Here's a test clip! (Currently running out the door)

Thank you for the test clip.

Everybody gets this wrong.

The first two seconds is supposed to be room noise only. This is what you sent:

Gasp, Shuffle Shuffle, Adjust Chair, Gasp, [Quiet] "Then the two girls..."

So no, there isn't enough pure, clean room noise there to measure. You have to be there because your body affects the quality of the noise the microphone receives.

That specification for ACX Noise? Quieter than -60dB? In English, that's noise a thousand times quieter than your voice.


There's something else a little wacky about your sound clip. It's high volume. Nobody does that, particularly with a USB microphone. It's so loud (how loud is it?) it's so loud you actually have tiny distortion on the word "Jasmine." Is that just how the Meteor works? That's Most unusual.

I'll record another and make sure I keep completely still! Before I do, maybe I should make an another adjustment though.

That's just how it records without touching any settings. Here's where I lose audio knowledge, but maybe I can adjust the input, or gain, or actual recording settings or something? I'm definitely far away from the mic and it still spikes all the time, I just figured it was something meant to be fixed in post. Let me know and I'll re record!

How do I figure out how "loud" it is?

Thanks

Audacity will be happy to tell you. If you look at the bouncing sound meter(s) while you record, we expect occasional bounces up to about -6dB to -10dB or so. If you have the blue waves set to display and update as you go, the tops of the blue waves should occasionally tick up about half-way. (50% and -6dB are the same thing measured differently.
I'm definitely far away from the mic and it still spikes all the time
Can you see the cartoon question mark over my head?

[To Self:] The microphone is too loud...........

I need to go back over your postings and see if I missed anything. I should look up your microphone again.

Do you use Skype or other Chat app?

More importantly, do you leave any of them running in the background in case a call comes in?

Don't do any more work until we resolve this. Skip the test clip for now.

I found this buried in a review.
during calls over programs like skype or discord. It tends to pick up a lot of background noise and really hums when I don't talk for a little bit.
"Ding!" That's the signature of Automatic Gain Control. One of your chat settings is taking control of your Meteor and setting volume without asking you.

So, which chat programs do you have? While you're recording, which icons in your dock have little white, blue or black indicators on the bottom?

I do have Skype, but it isn't in my doc and I almost never use it. I can uninstall just to be safe if that could possibly be the problem.

This video is exactly what I see when I play the recording back:

Does that help?

It does.

From the left: "Core Audio", Cute Microphone Symbol, "Built In Microphone."

You are recording your MacBook or iPad built-in microphone, not the Meteor.

[Stunned look.]

I said for a long time I could announce into my MacBook Air in a quiet room and almost get away with it if I was careful. No external microphone.
