Uses this macro https://github.com/jarikomppa/soloud/blob/3346bbc3c69ec3869337351dadde357b687b241e/src/audiosource/speech/klatt.cpp#L100

See the issue? The use of the macro only assigns stress to stressdur without doing anything with it. Is this intended? If so why not just assign stress to stressdur directly since the math of the macro is left unused.
