One more tiny test.

If you click on the recording sound meters, it should say "Start Monitoring?" and say yes. That allows you to listen to your microphone through Audacity without starting a recording. Still beeping?

The good-ish news is we can get rid of it in post production processing with the Mosquito-Killer tool set to 8 mosquitoes.

The fact that Mosquito-Killer works so well is a sign that it's a USB problem, but still not guaranteed. Why it it beeping on roughly a half-second (0.4 sec) rate? Normal damage is a constant tone. Digital audio is very resistant to interference. How is this noise breaking into the show? Again, normally, this happens with interference to the super sensitive parts of an analog microphone.
I did the tablet moving test as well and I didn't seem to hear a difference
That's too bad. That would have been an easy fix. I know they make noise if you get the microphone too close. But not that noise.

Google, of all places, came up with another idea. While you're listening to the beeping, unplug the microphone. You may get a loud pop when you do that, so watch your ears.

Yes, actually that was part of my test last night. No beeping when I listened through the "start monitoring" UNTIL I hit record, and the beeping started right up!

Thanks for googling - I tried Google but I couldn't seem to find anyone with the same kind of issue I'm having, maybe I wasn't looking up the correct keywords. :?:

Just tested this now - was listening through the laptop, had "start monitoring" going and of course, there was no beep. I clicked record and the beeping started up, waited a few seconds, unplugged the mic cable from the Scarlett Solo, the beeping stopped. Then waited a few seconds and plugged it back in while still recording, and the beeping started up again.
Does this mean the mic cable could be the culprit after all?

I don't know, this is so frustrating! I suppose I can dive into recording more auditions and seeing how mosquito-killer words as a longterm solution, but I've been holding out because last time I tried it I felt like there was still a loud hum (separate from the beeping) that was possibly involved in this issue somehow, basically the mosquito killer along with the notch filter someone recommended made my voice sound kind of wonky and kind of ruined the quality...
BUT maybe the hum was coming from something unrelated at the time and I didn't realize it. Will try again and see how the quality comes out, but still hoping for a real solution. :cry:

Thanks for the help.

I was being slightly devious. I searched for vague, fuzzy symptoms and let Google guess at it. And even then, I got that suggestion from an unrelated hit.

No. It means all the parts of your system hate each other. We ran into the same problem with the original Mosquitoes problem. There is no fix. The best you can do is change things around and get different noises. But we were working with "affordable" Windows machines and nobody's expecting top quality and stability from them.

It never happened with Macs.

It means you can make all the recordings you like as long as you don't use a microphone. Doesn't help, does it?

Oh, I know what the solution is. Stop recording on the computer.

We have forum posters cheerfully recording good quality work on Zoom H2, H4, H5, and H6 sound recorders. I produced my technically good quality audiobook submission on a Zoom H1n and a quiet bedroom. It fits in my pocket (the Zoom, not the bedroom).

Both the Zoom H5 and H6 support external XLR microphones. The Zoom controls and system are a little wacky and the H5 and H6 are outside of my personal experience. Please note these recorders can be used as USB microphones, but that's just asking for trouble. Use them stand-alone or on their own wall power supply and transfer files later. I calculated my 32GB memory chip would support something like 50 hours of stereo recording.

Oof, I don't think I can afford more equipment, even for a couple hundred dollars. Though I am open to the idea, I just don't think I can spend more money on it right now. :|
If I did invest in one, the drawback is that I would have to record everything straight through and then move it onto my computer to listen back, right? Sounds like it would majorly slow down the process or recording and re-recording bits.

The part of this that still baffles me is that when I first purchased the mic this wasn't a problem for a few weeks. I don't think I changed anything so what happened? What I wouldn't give to go back to that time...

I know it will let you listen to yourself in real time. I can check playback. But you're right. The current no-cost solution is with the Mosquito Killer as needed.

Killer doesn't affect your voice, does it? It's the hum suppressor that does all the damage. If you're trying to do all this work with Noise Reduction, that's a poor idea. Any noise reduction values much over about 12 or so can cause voice distortion.

We publish an actual hum reducer. Are you using that?


Are you recording on "shore power?" Is the laptop plugged into the wall with the adapter? What happens if you pull the charger cable during beeping? If you're on batteries, does it go away if you plug into the wall?

Can you tell if the hum comes and goes on headphones? There was one real life instance where someone was having trouble with their machine and I told them to pull the power cable. "I can't" they said. "The batteries haven't worked right in months."

Ding!

So the answer is yes, the Zoom will allow me to select and play a sound file from the memory chip. I know it will allow me to listen to my own voice in real time during the recording. That's "zero latency monitoring" for the record. Also called "Direct Monitor" on your Solo.

One of the techniques of live recording is to make a fluff, stop, breathe, clap or make some other loud noise (so you can find it later) back up one sentence and start reading again. Do Not try to edit in the middle of a sentence.

Go in during editing and delete the clap and the bad take. Because you're still "in the moment" during the correction, you're much more likely to have a seamless edit with swing, pitch and expression. This won't do you a bit of good if you change your mind three days later. Even under ideal conditions it will be difficult to make a correction days later. Only real actors can do that.

I can't wait for the results of the wall power test.

Here's the workup on the power hum remover.

There is a newbie "First Audiobook" effect. You get to the end of the book and go back and are horrified at the quality of the first few chapters...and read them again, now that you're a seasoned professional.

Ah yes. I've actually tried this test a bunch of different times, I had the same idea. No change at all (unfortunately.. I wish that was it). I tried unplugging the charger from the laptop all together, I also tried two different outlets all together, one a power strip and one directly into a nearby wall outlet. Nothing!

I think I need to do more research into this particular hum. Normally I usually use noise reduction, and did on my first finished audiobook. The quality of the finished audiobook sounded really good, but then when ACX published it the quality sounded so much worse, like they did something to it... (tips on this appreciated as well actually!) But I recorded on a yeti, so I had to do some noise reduction to get rid of the normal sort of "hum" My equipment/studio/setup just isnt good enough to forgo noise reduction altogether. That's actually what prompted me to switch to the Rode, which seems to have a much better sound quality (before all these issues!! and no massive hum initially.)

Someone recently suggested trying a notch filter with the really loud unusual hum that's now happening with the beeping. It's hard to differentiate between a "normal hum" and the "really loud new hum" I noticed more recently sometimes because I think I get so focused on the beeping...
That being said yeah it was definitely the notch filter that distorted my voice in my test last week (much moreso than the noise reduction), but it did remove the hum completely.
I just installed the hum remover, do you suggest keeping the settings that are preprogrammed in? The threshold is at 10 but it doesn't seem to do enough with the settings as is. Still isn't sounding great. In comparison noise reduction does sound better at least to my ears.

Backtracking, separate from the beep/hum -
I am waiting for a children's book to be approved by ACX that I recorded weeks ago with this Rode mic (pre-beep issue) to see if the quality is maintained or if it gets distorted by ACX like the books I did with the yeti. It's like they added a fuzzy noisy undertone to my first book that absolutely wasn't there in the files I submitted to ACX, it's a noticeable difference! Everything sounded pretty good on my end, even with the yeti as my mic.
If you're interested, this was the book, and if you click the sample and turn the volume up all the way you can definitely get a sense of the quality.
https://www.amazon.com/Mr-Hollywoods-As ... 5747&sr=8-4

I actually posted a topic about this and if there's a way to do something to prevent ACX from worsening my audio quality but didn't get much help. So while we're here please let me know you're thoughts! I was hoping the new mic would be a solution and it was before this whole mess started...
