I've been exploring the sample code from the ReplayKit sample code, here - https://developer.apple.com/documentation/replaykit/recording_and_streaming_your_macos_app. I'm essentially looking for a way to alter the below function to append the data from sampleBuffer to a file. I'm struggling to find relevant examples online or in the forums here. Any tips would be appreciated. func processAppAudioSample(sampleBuffer: CMSampleBuffer) {         print("Received an audio sample.") //Append sampleBuffer to file here ?? }

I'm trying to build a Universal Binary for use on Intel and Apple Silicon based Macs. However, under Xcode's Active Scheme list, for run targets all I see is "My Mac (Rosetta)" which suggests to me that my build will only support x86_64. My Architectures list is set to "Standard Architectures (64-bit Intel and ARM)". Any pro-tips?

(This is a repost with more targeted tags, as was suggested in the original question, here - https://developer.apple.com/forums/thread/651974) I'm working on my corny macOS Trash Talker (App Store Link) and something I've wanted to add for a long time is an ability to record the audio output triggered by the app. The audio output caused by this app is from calls to the Text-to-Speech engine within macOS, so I'm not sure if this output audio qualifies as truly coming from my app. I'm happy to use either Swift or Objective-C solutions as my App uses both already. I've looked for solutions to this for a while and so far never found anything relevant. Help or suggestions would be most appreciated.
