I found a version of Otosuite on their German website wiki.gnotometrics.biz.
Follow the Otosuite installation instructions. If your German is awful, you can use Chrome translate.
I only used it to get to the REM results in a NOAH-export and reuse them in Phonak Target. Don’t know whether they are up to date enough for running a REM-fitting with up-to-date hardware.
Don’t link to it directly, because we don’t want them to take it down.
