This gives a default 21.3 ms for an audio quantum, which is adequate if you have a RAM-based streaming device that completes transfers within 20 ms. With 1 look-ahead quantum, voices spawned by continuous containers are more likely to be ready when they are required to play, thereby improving the overall precision of sound scheduling. If your device completes transfers in 30 ms instead, you might consider increasing this value to 2 because it will grant new voices 2 audio quanta (~43 ms) to fetch data.
