Original stereo recording WAV 48 kHz is saved as mono 44.1 kHZ A first question was asked in issue no #505

Describe the steps taken to reproduce the problem, for example: After a lot of trial and error I now know what actions cause this problem. When Hi-pass-filter is activated (I usually use 200 Hz) -- downloaded extracts are converted from WAV stereo 48 kHz to mono 44.1kHz. If I deactivate this filter (= set to 0), the downloaded extracts are saved as stereo 48 kHz. Using LOW-pass or LOW-SHELF filters are not causing this problem. So I guess the BUG is within Chirpity and not caused by any settings in my PC

Please let me know if you need more info.

It looks like you are correct, the sinc and afir filters are resampling the audio to 44.1kHz mono. These filters are used for both LOW and HIGH pass filters, and it affects both.

I have a way to preserve the sample rate, but have no working solution to preserve the channels. I guess if that is what you want, you'll have to use the low shelf filter instead.
