[LMMS-devel] Stereo Enhancer

[mass_konfuzion <lh...@gm...>]

i was looking into how the fruity(loops) stereo enhancer works--it achieves a
stereo widening effect by shifting the phase of the input.  it shifts the
phase by delaying the input channel of your choice up to 500 ms.  to achieve
this same thing in LMMS, i think i need to extend the current stereo
enhancer that toby (or whoever) wrote to include a delay buffer.  so here's
where i need some help:

in stereoEnhancerEffect::processAudioBuffer (inside stereo_enhancer.cpp), we
have this:



> sample_t s[2] = { _buf[f][0], _buf[f][1] };
> m_seFX.nextSample( s[0], s[1] );
> 

i still haven't gotten through looking at all the code, but it looks like
_buf is responsible for pulling data from hardware.  then, LMMS steps
through the individual samples in the buffer, for processing.  is this
correct?  if so, then i would need to extend the stereo enhancer class to
include a software buffer that i can use for to delay the input channels. 
does this sound sane to any of you developers out there?  how would i go
about implementing this?


thanks,

- Lou
