I realize that Swipe has st: streng threshold and dt: sample rate parameters. But I'm not sure which of them is frameshift.

if by "frameshift" you mean the time increment between output pitch samples, that's dt.

The strength threshold is a value in the range [0, 1]: all pitch measurements that fall below the threshold are replaced with NANs (see the pitch function in swipe.c).

I see, the strength threshold is like voiced/unvoiced threshold. If pitch fall below the threshold, we mark the frame as unvoiced.

That's right.
