The click removal I can appreciate. But why is it necessary to capture

I capture at 88k/24bit, then clean it up, then downsample.

I don't have to get the record volume just right - I can lose a few
bits, then fix it in the digital domain - and having the extra doesn't
hurt at that point. I capture at 88k because it's easier to downsample
88k to 44k so I can write it to a CD, than it is to downsample from 96k.
OK, in theory you can go 96-44 with no trouble - but I like to make it
easy for the programs.

Downsampling from 88kHz is no easier than from 96kHz. You have to go
through the same process of interpolation, upsampling, lowpass
filtering, and finally decimation. Never try to do it by skipping
alternate samples - that way lies alias distortion from quantization.

And of course every audio ADC uses a massively high sampling rate,
followed by the procedure above to arrive even at 44.1kHz sampling.
