Recorded Preliminary Round
San Francisco Symphony just sent out a message saying that their committee has opted to do a recorded preliminary round in February, with semis and finals in April for their Section Viola audition. As far as I'm aware, this is a novel approach to have a time-limited recording period, and one that I hope other organizations emulate to respect the time and financial constraints of applicants.
Below is from their message to applicants:
Here is how the Recording-Only Preliminary Round will function:
Candidates will receive the preliminary round repertoire list at 12pm (Noon) PST on Tuesday, February 24.
Candidates will have until 12pm (Noon) PST on Thursday, February 26 to submit their recording.
The recordings must be done in one take and in the order of the list with no editing.

I like the recorded prelim a lot, actually. And audio only reduces the barrier to entry even further in my opinion, since requiring video either necessitates the candidate to have either a. a good combination video/audio device, or b. knowledge and software required to combine a video source with an external audio source. With audio only, an entry level field recorder and the sanctuary of a local church or high school auditorium will yield impressive results. I've advanced multiple times in recorded prelim submissions using this exact setup.
