Are there any AU hosts on iOS that can host mono-to-stereo AU’s? I’m working on an AU now where this would be the preferred configuration and the hosts I’ve tested in so far all seem to default to stereo-stereo even when I’m using a single input channel. It appears that they are all ignoring the channel capabilities that I’m setting as well and always setting the bus channel counts to 2 before calling allocateRenderResourcesAndReturnError. This happens even when I’m selecting a single channel from my audio interface as the input source.
My AU will function in a stereo-stereo setting, but it seems senseless to me to waste the computation resources in a situation where mono-stereo or mono-mono matches the use case better anyway. I’d also really like to be able to test in any host apps that do have this capability. Thanks, Rob
