I've made a little utility on Android that allows you to record audio > compress > encrypt > convert to base 64 and I am wondering if there are any ways to streamline sending the data over meshtastic or are there limits to the amount of characters you can send?

Converting binary to base64 makes the data 33% bigger, you should not do that when you have limited bandwidth

Good point, I guess using hexadecimal would shrink the data even further than using base64.

The compression was implemented to reduce the audio input drastically. It can compress audio down to 6kb/s and you can still interpret voice clearly.

I should try and optimize even further to shrink the final payload.
