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?
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.
