[fluid-dev] Stereo sample references in soundfont files

[Turner Hayes]

Hi all,


Perhaps a newbie question; I'm trying to render samples from a Soundfont 
file (I'm using FluidSynth's GM soundfont mainly) in Javascript (I have 
my reasons, heh). I've got mono samples working fine, but I'm a little 
confused about how stereo sample works; I notice that all samples marked 
as "left sample" or "right sample" have a sampleLink field value in the 
sample header of 0, which clearly can't be right (I note that the spec 
says that value should be the index of the corresponding sample--i.e. 
the right sample for a left sample, or vice versa). Looking at the 
FluidSynth code, I note that it simply skips the sampleLink field entirely.

I'm inferring from that that, despite the spec, the sampleLink field is 
not actually used in practice. What I'm trying to figure out is, what 
*is* actually used? Say I'm looking at a leftSample; how do I find its 
corresponding rightSample?


Thanks,


Turner
