I got some files sent to me as .amr files(small files ranging from 5 sec to 17 sec long). I have converted them to mp3 files but, those files would not play in traktor pro 3. It gives me the "files are missing, corrupted, or unsupported" error. I tried running them through MP3 Scan+Repair to fix corruption. I even loaded them up into Audacity and combined them all into a single audio file. Then exported as a .wav and it still gives the same error. These files play fine on every media player I tried but, they will not play in traktor pro 3. Any advice? I really want to add these to my sets.
