 describealign can be given a directory of videos and a directory of audio files rather than individual files. describealign assumes files from the two directories correspond based on their lexicographic order.

-By default describealign stretches audio descriptions to fit video, but the inverse is also possible: stretching the video to fit the audio description with the "--stretch_video" argument.

 ### audio-to-audio
 
-Whereas describealign is designed to align audio-to-video, it can also align an audio file to another audio file.

 ### boost
 
-describealign also has a few other experimental capabilities, like boosting the volume of audio descriptions relative to the video's sound with the "--boost x" argument, where x is in decibels. "--boost 3" approximately doubles the audio description volume, while "--boost -3" approximately halves it.

 ### keep_non_ad
 
-The default behavior of describealign is to replace all or almost all of a video's audio with the audio description file's audio. But the "--keep_non_ad" argument tells describealign to try to only replace audio when the describer is speaking. This can be useful when the audio description has significantly worse sound quality than the video.

-## Planned Features
-
-### GUI
-
-Many describealign users are describers or family members of the visually impaired, so an optional, cross-platform Graphical User Interface could improve usability.
