The expected latency with ogg or mp3 is 200+ms, the Celt end of Opus might 
be a better choice (5ms). Even Silk is probably higher latency than a 
sound generator wants. The latency listed for all these codecs is the whole 
chain: encode plus transport plus decode. OPUS gets it's lower latency in 
some cases by throwing away missing packets that ogg might be able to 
wait for. So it is possible that the decode part of all of these might 
have useful ideas.
