Occasionally when talking on platforms which utilize a raw push to talk, the last section of what you're saying will be cut off due to latency issues, so you have to hold the push to talk button longer than you need to. Discord solves this problem by adding a push to talk release delay, which keeps your microphone open for a set amount of time (I think from 0-1000ms) after you release your push to talk key. 

Is it possible to have this feature added to Ripcord?

Good idea.
