Doppler effect/relative velocity with Cinemachine camera does weird things?

Unity

Hi,

With these changes, all listeners will have Doppler enabled:

Change the SetListenerLocation in RunTimeManger.cs:

public static void SetListenerLocation(int listenerIndex, GameObject gameObject, GameObject attenuationObject = null, Vector3 velocity = new Vector3())
{
    if (attenuationObject)
    {
        Instance.studioSystem.setListenerAttributes(listenerIndex, RuntimeUtils.To3DAttributes(gameObject.transform), RuntimeUtils.ToFMODVector(attenuationObject.transform.position));
    }
    else
    {
        Instance.studioSystem.setListenerAttributes(listenerIndex, RuntimeUtils.To3DAttributes(gameObject.transform, velocity));
    }
}

Then add

private Vector3 lastFramePosition = Vector3.zero;

to StudioListner.cs and replace lines 99 - 137 in with:

private void Update()
{
    var position = transform.position;
    var velocity = Vector3.zero;

    if (Time.deltaTime !=  0)
    {
        velocity = (position - lastFramePosition) / Time.deltaTime;
        velocity = Vector3.ClampMagnitude(velocity, 20.0f);
    }

    lastFramePosition = position;

    if (ListenerNumber >= 0 && ListenerNumber < FMOD.CONSTANTS.MAX_LISTENERS)
    {
        SetListenerLocation(velocity);
    }
}

private void SetListenerLocation(Vector3 velocity)
{
#if UNITY_PHYSICS_EXIST
    if (rigidBody)
    {
        RuntimeManager.SetListenerLocation(ListenerNumber, gameObject, rigidBody, attenuationObject);
    }
    else
#endif
#if UNITY_PHYSICS2D_EXIST
    if (rigidBody2D)
    {
        RuntimeManager.SetListenerLocation(ListenerNumber, gameObject, rigidBody2D, attenuationObject);
    }
    else
#endif
    {
        RuntimeManager.SetListenerLocation(ListenerNumber, gameObject, attenuationObject, velocity);
    }
}

Please note this is just a workaround and once there is an update with a fix I will post it here.
