Abstract

TETRA includes an inherent audio delay of 53.333ms. A small one-off increase in the audio encoding time can result in this delay being further increased by 60ms. A solution is presented which reduces this 60ms incremental delay by as much as 49ms. The solution is also applicable to video delays.
