Perform quantization on /@samples@/ in /@in@/ and write the result to /@out@/.

In case the samples are interleaved, /@in@/ and /@out@/ must point to an
array with a single element pointing to a block of interleaved samples.

If non-interleaved samples are used, /@in@/ and /@out@/ must point to an
array with pointers to memory blocks, one for each channel.

/@in@/ and /@out@/ may point to the same memory location, in which case samples will be
modified in-place.
