Hello,
According to documentation, AVAudioInputNode shouldn't be able to perform sample rate conversion, but it appears that it can perform it on some cases.
The question following is: shall we or shall we not rely on AVAudioInputNode for sample rate conversion?
I wrote a complete project with two documented examples to illustrate the issue :

Thank you all 🙂
