USB Whine FIltering (Yeti Curse)

Nothing stops you from putting all of the names in the description. That way a search engine will find it.

all of the names in the description

I'm guessing Blue Microphones wouldn't be too happy about publishing "Yeti Curse" in the documents. I might leave that one out.

You might as well leave it out.

There's no way you're going to get on top of the search results as this also seems to be a popular term in the WOW/Runescape gaming community.

Only when you search for "get rid of the "yeti curse"" the second link is to this forum. But that's something most users will never do, imho. Too many words and it needs the quotes around "yeti curse".

We'll stick with 'USB Microphone Whine' and variations.

Mosquito-Killer4

PURPOSE

Some affordable USB microphones and other USB audio devices can add a constant, irritating, high-pitch whine sound (electronic mosquitoes) to your recording.

http://kozco.com/tech/audacity/clips/US ... neClip.mp3

The whine sound is very difficult to remove using normal tools, but we found the personality of the whine didn’t change that much computer to computer, so we designed a Nyquist effect to remove it.

USE

Select the work you want to repair, or all of the work by clicking just above MUTE (on the timeline left).

Effect > Mosquito-Killer4 (8 mosquitoes) > OK.

That’s it. We expect the whine to vanish in one pass with no adjustments and little or no audible sound damage.



COMMENTS AND NOTES

Mosquito-Killer4 is a multi-point Nyquist notch filter designed to search and destroy the most common, objectionable tones in the whine sound.

1000Hz, 2000Hz, 3000Hz 4000Hz, 5000Hz, 6000Hz, 7000Hz, 8000Hz.
That’s usually enough.

The tones are caused by USB electrical housekeeping leaking into the sound.

Please be clear we are surgically removing very tiny portions of show and you may hear some very minor performance changes. The changes are usually so gentle compared to the piercing USB whine that nobody cares.

...or just keen to experiment, you may find that your whine has fewer than eight significant mosquitoes in it and you can use the effect successfully with a lower number.

The number is adjustable 1 thru 16. As a general production rule, the fewer corrections, effects, enhancements and filters the better.

Best of all is to use a microphone or sound system that doesn’t whine.

Can you post the link to "Mosquito-Killer4"? I can only find links to earlier versions in this topic.

I'll straighten that out. The nomenclature didn't keep up with the code.
Koz

[kozikowski]

I didn't check with the OED, but other authorities assure me both mosquitoes and mosquitos are acceptable. The "e" version looks better. There's still one sentence that didn't come out quite right.

There may also be a code error. I've been testing with a non-standard version.

Koz

[kozikowski]

The man text above is good to go. That's the good news.

The less than good news is I can't correct the code. The corrections are based on Mosquito-Killer3.ny.

There are two changes:
;name is 4 instead of 3.
;name "Mosquito-Killer4..."

;control iter is changed from what I perceive to be default 5 to default 8.
;control iter "How many mosquitos to kill ?" int "1 - 16" 8 1 16

I did it multiple different ways including cp, vi and cat. No dice. I can't tell if the Mac is trying to help me sub rosa, or I just don't know what I'm doing.

You've got a mix of LF and CRLF line endings, but that shouldn't be a problem.

;name "Mosquito-Killer4..."

;control iter "How many mosquitos to kill ?" int "1 - 16" 8 1 16

Both of those should be OK.


Woah! What's that about?
Try trashing your pluginregistry.cfg and pluginsettings.cfg files, then re-install Mosquito-Killer4.
