I am trying to minimize the footprint of FreeSWITCH runtime and remove un-needed modules and their libs.
This modules is not mentioned any where and not much on the web.
Could u please provide more info on what functionalities it provides?
I'm planning to use FreeSWITCH for only SIP/sofia and Jingle/gtalk.

It provides support for reading most of the sound file formats that FS
supports. Almost anything that involves a sound file (e.g. voicemail,
playback, IVR, record etc) requires it. It isn't necessary if you're
just routing calls between endpoints, but anything more complex
probably requires it.
February 2020 : added config file for mod_sndfile (sndfile.conf.xml) which currently has only one param called "allowed-extensions" which allows to configure only certain file extensions to be loaded. Eg: <param name="allowed-extensions" value="wav,raw,r8,r16,ogg"/>
