Allow the annotation of audio files?
I think this has already been a feature request in the past and you are sort of able to do it if you turn your audio file into a video file. With the transcript option this seems now to be even more interesting. Would be kind of cool if you can add an audio file to your timeline and then annotate it like a video.
Video frame in post annotator could simply show the waveform image. Image related features (bouding boxes etc.) should probably be hidden. Maybe the whisper container is set to process only video files at the moment?
