$ mediainfo out-res.wav
Duration                                 : 7 s 997 ms

If I add --singleStage, then Duration is still not 8 s, but 7 s 999 ms.

Other resamplers I know of keep the sound duration intact.

Yes, this is a manifestation of the same problem as Issue #34

The good news is that I actually fixed it (in the source code). The bad news is that I neglected to compile and release the new binaries for it ! (my apologies)

I'm building a new set of binaries now, and will upload a new release shortly, once I am satisfied that it's all good.

here is what happens when I repeat your test above:

@sergeevabc I have published a pre-release of 2.1.1 Can you please see if you can get it running, and verify whether it has addressed the issue ? Many Thanks, Judd

Judd, I confirm that it works on my end.

By the way, why are the files created with the --singleStage flag slightly different in size?
