I'm not quite sure how to word this question, but is there any way to add reference lines to an ETC graph? You can hopefully see what I'm talking about below. I can take two images and overlay them in other software, but I'd really like to have the curves for reflection audibility threshold, image shift threshold, and echo threshold (see the Toole and Olive paper "The Detection of Reflections in Typical Rooms"). I know that this can be done by manually editing an impulse response... but that sounds like a major task.
