How to get PID from AudioObjectID on macOS pre Sonoma

3

I am working on an application to get when input audio device is being used. Basically I want to know the application using the microphone (built-in or external) This app runs on macOS. For Mac versions starting from Sonoma I can use this code:

int getAudioProcessPID(AudioObjectID process)
     {
       pid_t pid;
       if (@available(macOS 14.0, *)) {
        constexpr AudioObjectPropertyAddress prop {
            kAudioProcessPropertyPID,
            kAudioObjectPropertyScopeGlobal,
            kAudioObjectPropertyElementMain
        };
        UInt32 dataSize = sizeof(pid);
        OSStatus error = AudioObjectGetPropertyData(process, &prop, 0, nullptr, &dataSize, &pid);
        if (error != noErr) {
            return -1;
        }
    } else {
        // Pre sonoma code goes here
    }
    return pid;
}

which works.

However, kAudioProcessPropertyPID was added in macOS SDK 14.0. Does anyone know how to achieve the same functionality on previous versions?
