In theory there is no limit to the inter-sample peak level.
It *could* matter for some technical test signals etc. For
normal music signals even 0.5 dB should be enough, and even
if it clips you very probably won't notice.
Interesting. Well, I would catch any overs anyway when doing the dithering.
So, I compiled zresample without a hitch and it worked wonderfully. FYI, in
this case the input and output files differed by about 0.01 dB.
Thanks for the other suggestions (Hi Peter!).
