Calling C Developers for Audio

Hi,
I started a routing+dsp engine in c but it happend to be more work
than expected and I dont have the time to complete it so I am
calling you. If you are a developer interested in audio please
help us create the so needed engine for the comunity.

Some history - I took the way with a lot of channels, amps,
re-phase, equilizer apo, voicemeeter and it worked and I bought
the Atomic Pi pc to dedicate but 2 problems appeared:
1) my sound card driver exposes the card as 5x2 channel devices
insted of 1x10 and eq apo cannot route outside one device.
2) the UI of voicemeeter happens to be so heavy that it doesnt
leave resources for chrome and it begins to cut the audio.

I need to play sound from windows to a virual sound card,
then clone this 4 times, apply convolutions, play on real device.

The convolution I think is the easiest part.

The no.1 problem - channels are out of sync randomly, stereo
is displaced. When an input is already recording and there is data
and you turn on an output I dont really know from where to read
the input to be in sync.

Someone with libPortAudio experience?
