Re: [pygame] Why does pygame.sndarray.make_sound seemingly quadruple the sound duration?

[Mike Lawrence <mike.lwrnc@xxxxxxxxx>]

Thanks for your response. Support for your suggestion comes from
observation that changing the size from -16 to -8 yields an octupling
of the duration. So it seems that pygame.sndarray.make_sound isn't
properly accounting for the bit depth of the numpy array.
