Help. Little tics around 6000-8000Hz. Not mouth noises

Post by carnagecox » Thu Mar 04, 2021 5:46 pm

Hi experts

I'm relatively new to this bag, but from a technical background, and I've got along OK so far meeting the ACX specs after following the audacity instructions etc. However, I have a problem I can't easily fix. Yes I can edit out these ticks but it takes a LONG time and I'm down for a 9 hours audiobook!

Here's an image of what they look like and I've attached a clip. They are also present when I'm talking as well, you can hear if not easily see them. I've tried increasing the buffer to 200ms, and reducing the recording quality to 24bit. Not sure what to try next! Oh and I tried unplugging my mouse, didn't help. And I shut down firefox and other apps except audacity and open office to read the script from. Thoughts?

It's nothing obvious. Do the clicks occur if you record "nothing" (start recording then go and make a cup of tea / coffee, come back and press "Stop".)

What sort of mic are you using, and how is it connected to your computer?

Thanks for answering.
Just tried recording "nothing". No clicks. Then I did a bit of speaking, also no clicks. They seem to start to occur after 30s or so... I think they happen more often the longer the track. Clearly some processing issue... just don't know what to do!

I am using a marantz pod pack 1. USB. I tried using a different USB port, didn't help.

Thanks!

Can I move this post to the audiobooks area please? I might get more help. These clicks seem tiny but they're really significant in a audio book!

I've moved it, but it's usually the same half dozen people that answer questions.

How long were you recording "nothing" for? If only a few seconds, try it for a few minutes.
Do NOT turn down the recording level when recording "nothing", leave everything exactly as it is when you are recording your voice.

What settings are you using the Device Toolbar?

Do you have a portable radio? If so, repeat the test with the addition of the radio playing near the microphone.

The next test after that is to replace the radio with you talking

Hi
Just tried that. Ran it for a minute by the radio, both a woman and man presenter spoke. No clicks. However, the waveform is very different. The whole thing is much more noisy. I did a noise reduction to see if that allowed some clicks to appear but it didn't.
Thanks

Curious.
Now try again with you speaking instead of the radio. Do to recordings, one where you speak any old nonsense but concentrating on not moving while you speak, and one where you relax and do a "normal" voice recording.

Hmmmm well if you insist! But when I record I don't move; I'm aware any motion can be picked up so I get comfortable, stay still and go for it.

What's interesting to me is that the frequency (how often, not Hz) of the occurrences appears to increase during the recording. I really think this is a processing issue of some sort. I appreciate that gives no explanation of the radio result. UNLESS the radio audio is easier to process? I know too little about the type of processing which goes on during a recording to speculate.

Thanks
