What equipment are you using for recording?

There are a few minor low frequency peaks, but nothing that is not also present in the "No Audible LFN Clip.wav". This leads me to think that the "sound" may be a vibration below 20 Hz, so not strictly speaking "sound", but a vibration that you perceive as "sound&q...

Here's a function that generates pink noise without filtering. The algorithm is the same as is used in the Audacity pink noise generator. Unfortunately it is rather slow, but the quality is good. ;;; Generate pink noise (defun pink (&optional (dur 1.0)(amp 1.0)) (setf pink-class (send class :new...

That's pretty close.
The coefficients used by Edgar appear to have originally come from here: http://www.musicdsp.org/

Are you selecting "MP3" as the file format?

If you have the "VST bridge" plug-in, you should remove it.

There is a distinct rumble, similar to a distant tram or lorry, on the "No Audible LFN Clip.wav" ! (it starts about half way through the clip, drops off, then comes back in the last couple of seconds.) I presume that this is a different sound - not the one that is causing the problem. It i...

If you only need the Audacity software, you can get it here: http://audacityteam.org/download/

If you require any special drivers or other software, have a look at the documentation for the device and see if they have a website or an address for "product support".

I first like to change the hKz/Bit to 96hKz/24bit. That is unlikely to be of any benefit. The default bit format for Audacity is "32 bit float" which is the recommended (most accurate) format for audio processing. Increasing the sample rate will slightly reduce the sound quality due to ti...

I thought to hear a sort of low level plop-impairment when applied with higher concentrations or on longer clicks. That is probably inevitable. In the case of longer clicks the "true" audio is missing - replaced with "click" noise. There is no way that an effect can accurately g...
