Ok as you describe the model details the noise is.from Cvt transmission you are facing a lime fluid pressure loss problem due to overheating of CVTF Fluid which is a major fault in new gen 1KR-FE equipped K410transmissions whoch uses CVTF FE fluids
THE main problem i heard in your voice record is excessive torque convertor whinning so get it diagnosed asap the only option to resolve the issue is immediate CVTF fluid temperature analysis and valve body obstruction clearing by servicing the valve body assy along with complete transmission fluid flush with A denser CVTF fluid .
