It can form the basis for testing/comparing various APIs, like
avcodec_decode_audio3() / avcodec_encode_audio() for example
but theres not enough time before the outreachy deadline to add actual
support for these now

i would guess, its intended to generate a signal thats different
for each of the 2 channels, Ludmila can probably confirm/or correct
if its not so
i dont see a problem here, its not the most variied test signal but
for now that should do. It can be chnaged later
