How many frames does soxr output if, given ilen input frames, olen = ilen*orate/irate is not an integer? I'm working on an application where I'm streaming data in and out on stdio (like examples 2 and 3), and need to output a WAV header before soxr's output -- which requires knowing the exact number of output frames in advance, since I can't seek on stdout to patch up the header later. (This is assuming constant-rate files, of course.)
