Benjamin and list, I double Benjamin’s request. It would be great if someone from the CoreAudio Team could respond to the question.
Two years ago, after basic tests I realised that AVAudioEngine was not ready for Low Latency Audio analysis on iOS. So we used AUGraph. I have a feeling that this is no longer the case on iOS and we can move to AVAudioEngine for low-latency audio processing. Anyone can share experience here? We do real-time spectral analysis and resynthesis of sound and go as low as 64 samples per cycle if the device allows. Thanks in advance. Arshia PS: I actually brought the deprecation issue of AUGraph in a local Apple Dev meeting where the EU director of developer relation was present. According to him, when Apple announces a deprecation, it WILL happen. My interpretation of the conversation is that AUGraph is no longer maintained but provided as is. > On 11 Jul 2018, at 12:36, Benjamin Federer <benja...@boinx.com> wrote: > > Since it was mentioned in another email (thread) I’m giving this topic a > bump.
