I'm exploring the use of Unity's own audio IO interfaces at the moment as it will probably provide a more streamlined Csound experience for the end user. However, Unity uses floating point samples for audio, if I use a doubles build of Csound and simple cast to float should it work Ok? At present I'm getting some unwanted artifacts in the output audio. But it could just be my processing routine. I thought I'd ask here first before I go pulling things apart Rory style!
