Hello. I use the Stadium XL V1.2.1 and I can’t import the IRs in WAV format into the library of the Helix Stadium application, whether it’s through a dropped drag or by importing one or more files. All my IR files open without problem in the windows media player for example and make a sound. Here is the error message that appears in the app: Librarian operation failed. (error code -5). Can you please help me unblock the situation?
