Ok, here's a page relating to Chris' dynamic compressor, including download link, etc.:

Will try it out/play around with it a bit.


Stay well

Normalize doesn't help because the original dynamic range is exactly the same.

Use a compressor or Automatic Gain Compensation.
Chris' Compressor belongs in the latter category, although not named like that.
I also recall that one has written a dynamic audio normalizer which
does the normalization frame by frame.

While my primary work machine is a lenovo w52 laptop, with a conexant
internal microphone - unfortunately, it's only 3.5mm audio jack is one
of those combined ones, and none of my headphones with built in
microphones seem compatible with it - even the primary vocal recording
headset which has an adapter to combine the two leads into one.


So, while I don't generally even try use this machine for actual audio
recording, there are times when I want to quickly record something, or
play around with effects, etc., etc., and, the issue was that it seemed
to be fluctuating recording volume levels up and down during a recording
so that, for example, if I counted from 1 to 30, going up to roundabout
30 seconds, it would drop off after 8-10 seconds, then up volume level
again after roundabout another 8 seconds, drop it off again, etc. etc.


Seems like if I disable a setting under the sound card settings,
recording device, advanced, called audio enhancement, then this
fluctuation then goes away, but, I was still trying to figure out how to
get audacity to help me level out volume levels across a track like
this, but, while I thought normalise was the effect to work with, it
didn't seem to handle it very effectively.


So, unless I was trying to use the completely wrong effect, just
wondering if there was something specific I should have tried in any case?
