Thank you! We will be working on video after we implement more image transformations. What is your usecase for audio and what transformations would you like to see?
My use case is in education, with users uploading short audio clips. Often these are in a variety of formats. It's nice to be able to re-encode them all to the same format and save as much bandwidth as possible as well as make sure they are supported in the weirdest variety of devices.
