Stereo > Mono Downmixing on iOS

Hi,

I’m trying to downmix a PCM stereo signal to mono on iOS (realtime). The input consists of the two (stereo) channels, which are processed through a number of effects, and in the end I need two channels back out, where each channel is a mono downmix of the stereo signal at the end of the chain (i.e. both output channels would be identical).

I though I could maybe use the AudioConverter but it doesn’t seem to do mixing, and the MultiChannelMixer seems to be quite limited on iOS as well in terms of output channel configuration.

Any input would be appreciated!

Thanks! _______________________________________________
