src_simple with sndfile

[puronas]

FYI - I've been having some trouble trying to figure out why my code would compile but produce silent WAV files. Turns out it was completely basic user error dividing two integer values:
sf_data.src_ratio = new_samplerate/old_samplerate;
Which essentially produced an integer value and messed up my src ratio. (float)new_samplerate/old_samplerate was the solution.
This can be deleted or left in case somebody else bumps into this.

Hmm, ok : 😊

Maybe add this to the documentation perhaps ?
