Crash upon engine start about beethoven HOT 5 OPEN

I haven't experienced this, but you can try one of the solutions from that stack overflow post, such as replacing node.outputFormat(forBus: 0) with AVAudioFormat, and make a pull request if it fixes your issue.

@hannah-bennett I guess you're getting this error when using simulator, try to run your code on an actual device

Thanks for the response. These are device crashes, not simulator crashes. I'll dig into it and see if I can pinpoint what's going on.

you should call removeTap before install. Give it a try.

InputSignalTracker.swift

  func start() throws {
    ...
    inputNode.removeTap(onBus: bus)
    let format = inputNode.outputFormat(forBus: bus)
    inputNode.installTap(onBus: bus, bufferSize: bufferSize, format: format) { buffer, time in

Wouldn't it make more sense to set inputNode.inputFormat() instead of inputNode.outputFormat?
