OptimFROG - Send a File
Here you can send me any audio file (no size limit) which you think it does not compress well with OptimFROG compared to other lossless audio compression programs, illustrates a problem of any kind, or you just believe it would be interesting for me to test.
You must enter a real e-mail address, so that I can contact you back, and also write a small explanatory text about the file you are sending.
Thank you for your time and for helping to improve OptimFROG!
