Clicks and buffer

I want to eliminate the persistent, tiny yet audible clicks in my Yeti Blue Pro voice recordings on Windows 10.

In my research online I found that there are several potential causes and solutions, most of which I have already addressed.

One potential solutionrelated to Audition is to increase the buffer size. An AI article says :

Go to Edit > Preferences> Audio Hardware and increase the buffer size.. A larger buffer will reduce the likelihood of clicks but may increase latency, so balance this based on your needs.

Ok. Except that there is NO buffer setting in Audition, only Latency - unless this is the buffer labelled LATENCY (just to confuse everyone). In Audacity I used to use some years ago, Buffer and Latency were two separate settings. Go figure.

Is this the actual buffer size setting? if so, I have it already set at the max 500 ms and yet the clicks continue.

Removing them is very time consuming, as the Diagnostic plugin is not very subtle changing the quality of the whole highlighted audio, so I need to remove 99% of them manually one by one., to preserve the audio quality.

Grateful for advice.

Yes they are the same thing but confusingly labeled. If it's tiny clicks, it won't be the buffer settings - errors there are far more audible. Are you trying to record in Waveform, or Multitrack view? And can you provide a short sample of these clicks?

I record in Waveform only.

Interestingly, when recording last night I reduced gain by few degrees (from about +5 to -5) on the Yeti knob, and to my surprise, there was a reduction of clicks by about 50% . I can't reduce any further as the recording level gets too low.

here is a sample.

not sure what is the best format here so have attached both wav and mp3

thanks

As all actual engineers know, it's not what a specification tells you that's important - it's what it doesn't tell you. And you can cannot really determine anything about the behaviour of a device from its specification alone - there are many, many examples of this. It is even possible, in this instance, that reducing the sample rate from 192k to 44.1 might actually help your situation; stranger things have been known. And that's the point; you can't determine what will make a difference just by looking at a piece of paper, especially if you haven't been trained to interpret what it says correctly. And in this case, you need to be aware of Shannon and Weaver's work, and Nyquist limits before you even begin.

Let's just look at what it is you can actually hear: (This occurs in a lot of places in your file, on both channels - there are many more)

The bits I've ringed in red show pretty good examples of instability somewhere in the impedance converter and preamp stage of your mic. The problem has to be there; there is nowhere else analogue in the mic before the USB conversion, and if USB converters did this, we'd all have been up in arms about it years ago. This sort of instability can be 'provoked' by having the gain turned up too high, but there are other possibilities too - mainly involving poor design. The relatively smooth part of the waveform is actually you speaking, but the waveform superimposed on it gives the whole thing a 'grating' sound.
