--- Comment #11 from Nicolas Dufresne (stormer) <nicolas at ndufresne.ca> ---
S24 is always an inefficient format. That's because you need to read per byte
since data is not aligned. Other then that, audiotestsrc is not really fast
generator, it's just a test tool. Though, feel free to propose a patch, and
rename the title accordingly (e.g. by mentioning this is about audiotestsrc
instead of audioconvert).

p.s. You'll notice that sine waves have repetitive pattern, it's kind of silly
not to cache the generated pattern ;-P
