[alsa-devel] performance between access mothods!

Hi all!

I came across a doubt regarding the the access mode between application and PCM device. It is a hardware parameter related property and there are 5 different types available:

SND_PCM_ACCESS_MMAP_INTERLEAVED SND_PCM_ACCESS_MMAP_NONINTERLEAVED SND_PCM_ACCESS_MMAP_COMPLEX SND_PCM_ACCESS_RW_INTERLEAVED SND_PCM_ACCESS_RW_NONINTERLEAVED

taking in account that these first 3 parameters has direct communication with the memory, that means a higher speed operation? And the fact of the interleaved has all the samples mixed together , makes any difference in performance in comparison to the noninterleaved that has samples stored on different buffers?

Thanks in advanced
