Hiss Reduction Filter

This is a minor problem which is present in 3.6r2 as well as 3.7 beta 4.

I prefer to record at 44.1 kHz 24 bit however the hiss reduction filter (14dB) doesn't work with these settings.
(It's obvious if I audition through headphones that no correction is being made)
The noise sample has been correctly adjusted.

This applies whether the recording is made in WC or another program and then imported.

If I record at 96 kHz 24 bit then the hiss reduction is applied correctly.

I know I could record at 96 kHz and then down sample on export (my sound card doesn't support 88.2 kHz).
However I prefer 44.1 kHz as my recordings will be transferred to CD and the original file is smaller for archiving purposes. A 24 bit recording gives me some headroom to normalise etc.

Vinyl click correction seems to work as expected but I'd be grateful if you would confirm this is correct.

Many thanks
Richard.

Apologies for not replying earlier. For some reason, missed this comment.

Yes, this is a definite bug that affects 44.1 and 48 kHz 24-bit files. I've now tracked down the bug and it will be fixed in the next beta (5).

This is fixed in beta 5, now available on the beta page.
