问题
I am working on an amplitude-based visualizer for macOS using the latest versions of AudioKit (4.9.3), Swift (5.1.3), Xcode (11.3), and macOS (10.15.2). I had this working at one time (using earlier versions of each of those things), but now I get the following error messages at runtime:
2019-12-14 17:48:45.549957-0500 Dockside2[903:10790] [plugin] AddInstanceForFactory: No factory registered for id F8BB1C28-BAE8-11D6-9C31-00039315CD46

2019-12-14 17:48:45.566473-0500 Dockside2[903:10790] [ddagg] AggregateDevice.mm:790 couldn't get default input device, ID = 0, err = 0!
2019-12-14 17:48:45.582337-0500 Dockside2[903:10790] [avae] AVAEInternal.h:76 required condition is false: [AVAudioIONodeImpl.mm:1063:SetOutputFormat: (IsFormatSampleRateAndChannelCountValid(hwFormat))]
This is the function I call to initialize AudioKit:
func startAudioKit() {
AKSettings.audioInputEnabled = true
input = AKMicrophone()
amplitudeTracker = AKAmplitudeTracker(input)
AudioKit.output = AKBooster(amplitudeTracker, gain: 0)
do {
try AudioKit.start()
} catch {
AKLog("AudioKit did NOT START")
}
input.start()
amplitudeTracker?.start()
}
Can anyone make heads or tails of these errors? Extensive searches haven’t yielded anything.
As far as the error regarding AggregateDevices, that's interesting because I am not trying to use an aggregate audio device. I am just trying to get it to work with the default microphone input. However, I should mention that in a previous version of my app, which was actually working at one point, I was using an aggregate device via SoundFlower for the input. I have since uninstalled SoundFlower entirely and removed the aggregate inputs from Audio MIDI Setup.
Update: If I run the MicrophoneAnalysis example exactly as provided from AudioKit.io, that doesn’t work for me either. I get these similar error messages:
