Base64 encoding for audio files

Base64 encoding for audio file.

I have to send the audio files recorded within the app to my server in real time. Now there is no way to do that directly so I have to first upload the files to Cloudinary, and then pass the links to my server for it to retrieve files from Cloudinary using those links. Being able to send audio files (e.g. base64 encoded) to my server would decrease the latency dramatically.
