Fix The Fraunhofer MP3 Encoder
when I export a file as MP3 with 320 kbps quality via Audition, frequencies between 16 kHz and 20 kHz are cut off. this problem is independent of the source file. for example, when I export a FLAC file as MP3 this happens. When I edit a full frequencies range MP3 file (20 Hz - 20 kHz) and than export it this problem also happens too.
The funny thing is that when I do the export process with Audacity which is a free and open source software, this problem does not happen. I tried the same experiment with other paid softwares such as Acoustica 7, iZotope Ozone 9, iZotope RX 9 Audio Editor, and as I mentioned, frequencies above 16 kHz are not cut like Audition in any of them. I think this problem is caused by Fraunhofer MP3 Encoder but I can't do anything to change it.
So I ask you developers to solve this problem. Instead of Fraunhofer MP3 Encoder, you can use LAME Encoder like other softwares as I mentioned above, or at least you can add a setting to the program where we can change the Encoder even if you do not use it officially, thanks.

hi there, thanks for the reply but i don't use VBR for my MP3 exports. so i used CBR in that screen shot where the 16 kHz frequencies cut off. to be more specific i used 44100 Hz, Stereo, 16-bit, MP3 320 kbps CBR. and also as far as i know i can't get 320 kbps mp3 with VBR right..

The Audition screen shot appears that you are using the VBR instead of CBR. Can you confirm?
