Sounds like it's worth setting up a simple test and profiling...

Hello list,I understand it's preferable to keep stride size to 1 when using the vDSP functions of the accelerate framework. Does anyone have any experience (or numbers) relating to performance and stride size of greater than one? I have a single-channel envelope signal that I'd like to apply to an interleaved stereo signal. If I can get much better performance by using a two-channel envelope signal (this keeping the stride to 1), I'll consider reworking my code.
thanks,
