Well although Bridge is included with Audition it has limited functionality with audio files. It was originally designed mainly for graphics files and picture with add ons for video and audio. I find that some of it is a bit hit and miss with Audition. You can use it to manage .wav file metadata but there is a problem. The fields available in Bridge do not fully reflect those you can fill in in the RIFF header from File Properties in Audition and there are some that don't show in Audition if filled in in Bridge. Which is daft in my view
