Hello, I've posted this question some weeks back, but didn't receive any reply. The question is quite serious for us, the accessibility developers: How to use Pulse Audio API so that we achieve small latency? Where can one find some documentation on the glitch free model from the perspective of an application developer? Former question bellow. With regards, Hynek Hanke Hello, please, how do I ask Pulse Audio using the asynchronous API for a small latency setup? Currently, in our setup, Pulse Audio adjust the latency to 80ms (total) while playing sound from our application, but it won't go lower. This is however very high for our purpose (speech navigation for the blind), we need to get it at least to 20ms. Thank you, Hynek Hanke
