I need help with exporting data for my university project. When I export data for RT60, RT30, RT20, EDT, C50, C80, and D50, the full range value of RT60 is zero, but the other values are okay. I'm confused about the correct method to calculate the full range of RT60, as well as EDT, C50, C80, and D50. If someone can solve my problem, I would be very thankful
