What VR-compatible sound assets would you like to see in the Marketplace?

Hi all, 
I’m doing some research at the moment on how current indie devs are working with audio in your VR projects, especially SSD (spatial sound design), and which type of audio assets that you feel would help make it easier? I’d be very grateful if any of you would like to answer the two questions below:

  1. How do you currently work with integrating sound into your project?
  2. What sound assets would be useful to you (for example; ready-mixed spatial files of various environments as TBE-files etc./mono audio objects) and how much would you be happy to pay for a package?

Many thanks,
