It would be useful to have a similar iterator that gives a whole frame per iteration (i.e. one sample per channel in a slice) as that's usually the unit of processing.
Would iter::chunks suffice for this? You might think that Hound could do a more efficient job, but it is difficult in general, because the underlying interface is a Reader, not a slice.
A similar feature for the writer would also seem useful.
That sounds like it could be useful indeed, not just for frames but for arbitrary slices, to save the overhead of checking the result after every sample. Even more general would be to accept an iterator rather than a slice. I added SampleWriter16 with a similar intent, but it is "push based" in the sense that it still requires writing every individual sample. That is more general than an iterator though, because you can easily do .for_each(writer.write_sample) on an iterator, but turning something that is not an interator into one is a lot harder. Taking a slice could still be useful just as a convenience method though.

Currently there is only the samples iterator for reading files. It would be useful to have a similar iterator that gives a whole frame per iteration (i.e. one sample per channel in a slice) as that's usually the unit of processing.
