Lowpass filter.
Can be used before lossy encoding, if your encoder of choice doesn't have lowpass filter with arbitrary frequency.

This lowpass filter is just a part of SoX resampler. This plugin is just truncated resampler plugin.
I don't know how to properly implement subsonic highpass filter.

So far this has been a sort of week-end fun-time a plugin in for me. I load my playlist with sufficiently percussive material, then I set freq to 3500 and width to 1%. The chirpy ringing is really amusing. From here on tweaking phase lets you hear the difference between pre-ringing and post-ringing very clearly.

I suppose the default width of 5% is reasonable when used prior to lossy encoding?

Plugin messes up channel mask for non-standard channels layouts. For example 5.0 becomes 4.1 when passing through plugin.
