Hi,
I have a dumb question on LADSPA.
Can I use LADSPA to implement the following processing plugins?
Bass Boost
Stereo Widening
Virtual 5.1 Surrounding
I asked this because I've got some audio post-processing
requirement in my design I'd like to see if I can
leverage the LADSPA to do that?
Thank you in advance.
Regards.
Long

Hello Long!
In fact two out of the three are definitely in place. You have in the
swh-plugins the matrix_spatializer (I believe, uniuqe ID 1422), which allows
for stereo widening. And you have EQs fromdifferent plugin makers. I guess,
they'd be OK to boost bass frequencies.
I'm not 100% sure about the 5.1-encoder, but I remember reading something to
that effect. If I missremember that one, you can at least do it in a LADSPA
plugin. But wait for more answers first.
Kindest regards
Julien

Hi Julien and Long,
Julien: You might be thinking of the 1401/surroundEncoder. It's unfortunately
not 5.1 but 4.0.

Long: You might also be able to work something out of this but that is of
course not LADSPA.
