Hi!
Hui and I have been working on some LFE filter patches lately, and this
is our first draft for review/feedback.
First, I have greedily stolen the math from CRAS, because CRAS is BSD and
as I understand we don't have a problem with merging more liberal licenses.
The LFE filter is implemented in the resampler, which means it is done for
every sink-input rather than every sink - this might mean some additional
CPU processing if many different streams play back at the same time, but
putting it on the sink side would disable the possibility to mix a 2.0 stream
with a 2.1 stream.
The rewind part is very drafty and untested, and I'm not sure I choose the
best design here. But at least this is something that could act as base for
discussion.
Sorry for a possibly-stupid question, but...
Which part of PulseAudio is supposed to disable the effect if the user
plugs headphones in? Or is it yet to be written?
