Attached is MultiNotch, SetRMS and LF-Rolloff. You need to unzip LF-Rolloff. You'll need to flop back and forth between those tools as needed. There is only one Nyquist Tool, so you'll need to keep opening the different programs as you need them. Once you get Equalization working, that's just a selector window to go back and forth.


Open the show.

Effect > Nyquist Prompt: Load > MultiNotch.ny > OK.

Effect > Equalization: Select Curve: LF rolloff for speech, Length of Filter, around 5000 > OK.

Adding Audacity Equalization Curves
-- Select something on the timeline.
-- Effect > Equalization > Save/Manage Curves > Import
-- Select LF_rolloff_for_speech.xml > OK. (it won't open the ZIP. You have to decompress it)
-- LF rolloff for speech now appears in the equalization preset curve list.



Effect > Nyquist Prompt: Load > SetRMS.ny > OK.

Effect > Limiter: Soft, 0, 0, -3.5, 10, No > OK.

Effect > Equalization: Select Curve > VE4VoiceEq > OK.

Effect > Noise Reduction: 6, 6, 6 > OK. If you want a little more suppression use 12, 6, 6. Don't go over that.

Analyze > ACX Check

Missed one. SetRMS has settings but the default ones should be good to go. You should always be in mono (one blue wave), so the stereo settings don't mean anything.

Target RMS: -20, Linked Stereo

It's looking more and more like VE4VoiceEq is an equalization curve I made for someone else a while ago. It's a little honky in this case so I'll probably see if I can stop that and still "crisp up" the voice a little—get rid of that flannel blanket sound.

That and I changed the order of application.

Multi-notch
LF-Rolloff
SpaceShipVoice
SetRMS
Limiter
Noise Reduction


The old list messed up the loudness and peak settings. The new one takes everything into account.

Did the posted, corrected sample sound reasonable? The new voice quality equalization I left should sound more natural. Did I lose you in the process? Higher end microphones do better. I recorded a sound test in my super quiet third bedroom with a good microphone and I got one test to pass just by making it louder. We kept telling people you could do that so I wanted to see if I could.

Lower end microphones can start a death spiral. The volume is too low so you correct that. That brings the noise up, so you fix that. That makes the voice sound funny.........

We know what it is. That's the USB data flashing back and forth getting into the little part that catches your voice. Higher end microphones and other devices don't do that because they have additional protective shielding and filtering to get rid of it.

Expensive filtering. The difference between the Yeti microphone and the Yeti Pro is double the price. The whine doesn't happen to everybody.

You are also missing performance and quality issues that many other people have with much better equipment, so you really got lucky.

Fixing that wasn't "free."

MultiNotch written by Steve brutally smashes certain musical tones that we determine were the worst offenders. They're just gone. We're hoping nobody looks too hard at the show and you don't try to send music through the system.

The tones are 1000Hz, 2000Hz, 3000Hz and 4000Hz. Those roughly correspond to the signals that USB uses to do its job. You might know what 1000Hz is. That's one of the tones Broadcasters use, for example, behind colorbars as a test signal.

The more normal test tone is 400Hz. Never being one to follow the pack, NBC New York used 400 and NBC Washington used 440Hz.

You totally know what 3000Hz is. That's a baby screaming on a jet. That's one of the reasons this whine sound can be low level and still so irritating.

Normal piano tones don't ever land exactly one one of those tones, but if you have an instrument with no fixed pitches such as a violin or a slide trombone, you could hit musical tones that don't make it into your show.

And you thought this was easy....

I just got a chance to listen to the "fixed" version with no mosquitoes, and it sounds GREAT to me. Thanks for all your hard work.

I'm mostly interested (of course) in passing the ACX check robot, without getting over processed, so it's been good to get a little feedback before committing to reading a whole book.

Anyway,

Thanks again.

Each time we correct a performer's work, we get better at it. This pass saw the debut of MultiNotch. Until now, that was the digital equivalent of writing a filter program on a napkin at a breakfast shop. I remember seeing it posted for someone else and I went down the listings until I found it.

ACX Check looks like a simple and perfectly obvious tool, but if I told you how you had to do it using the older manual effects, you'd fall on the floor laughing.

And etc.

I think I used 12, 6, 6 in the best version of Noise Reduction. Noise Removal of the Beast (6, 6, 6) isn't quite enough for you.
