It can't convert my sample file

[campidelli]

I am using a Mac M2, have installed Rust and installed the program as suggested by the README.

This is the error I get (after exporting RUST_BACKTRACE=full to get more details):

I've been seeing the same issue. In a directory of 20 NCW files, over half of them couldn't be converted due to this issue.

[cheesymoo]

for the file shared here it was 512 samples of difference between the two values.
