Yes, I think so. You can try to write the author about that (on TimeFreezer site). It has not being developed for a while ad it seems abandoned, but the site is on and it seems that it can be bought.
It's still working on my Mac (OS 10.14 Mojave, at present, but planning to update my MacOS soon, so in the future we'll see if it will work also on my updated Mac).
It's a real pity how the best and most accurate softwares are sometimes those that get abandoned. In this case, people seems not to understand that the fidelity to the original given by TimeFreezer is superior, better than that achieved by most of the other similar resynthesis tools: you can have a voice saying an "S", or even a "T", or a short percussion attack in your sample, and still, with TimeFreezer, you can go to and fro extremely slowly through that small instant of sound practically without audible changes in the timbre with respect to the original (if the settings are correct).
