I run a recording studio in South America, and became very interested in Har-Bal for doing “client mix versions” before sending the material to the mastering facility. Is there any Demo Version which I can test so I can verify if it will fulfill what I need?

There is a demo player application with filters to demonstrate the capabilities of Har-Bal that you can obtain below:

If you want to be able to demo it on your own material then you have to buy it and exercise the money back guarantee should you find it unsuitable for your needs. There is no fully functional demo and we don’t intend making one available in the future.
