I assume that you're talking about the /sounds resource available in ARI
[1].
At Wazo [2], we use the /sounds resource to list the sound files that
are register in Asterisk.
It allows us to implement a REST API that gives an overview of what
sound files are available and in what languages.
This REST API is then used to display the list of sound files in a web
page, or to select a sound file in an application, e.g. when creating an
IVR and selecting a sound file to play. The REST API is also used to
list the available languages for sound files.
We have used the /sounds resource when we could, but we still had to
access the file system directly at some point in order to offer more
features in our REST API, like uploading custom sounds, streaming the
sound files or accessing recording files.

Thanks Sébastien.
What kind of response time are you getting when you retrieve the full list?
The reason I'm asking is that when Asterisk starts, we pre-populate an internal cache (media_index) with all the sounds which, depending on which languages and formats are installed, could easily be 20,000 files. In some instances, users are creating symlinks inside the sounds language directories to other places (like voicemail) which now will also get indexed. In one case, we had a customer with an effective list of over 800,000 sound files. This takes quite a bit of memory. What we're trying to determine is the value of the cache considering that we're only caching directory entries (not contents) which the filesystem has already got cached. In tests of the ari/sounds resource, 95% of the response time is constructing the JSON response, even when not using the cache. I.E. The cache made no appreciable difference in the response time.
