Is there a module in FreeSWITCH (from GitHub) that allows programming bit transcoding?

Hello everyone
I need to find a module that can be programmed using the FreeSWITCH source code available on GitHub. This module should be able to perform bit transcoding. I need to convert audio to 24 bit / 48 kHz.

Thanks.
