Hello everyone,
We are trying to build a Sox based real-time sound altering app, and we’ve got everything working on our LUbuntu 16.04 stations except for an issue w latency.
When we test it on actual hardware, we are having a latency of about 2 seconds, when we test it on our virtual machine the latency is more like 250ms.
sox -t pusleaudio default -t pulseaudio null pitch n
Whenever we add the null loopback or aloop, we experience a delay. No amount of config tinkering seems to affect this latency on an actual workstation.
We’d appreciate an advice or any input but would be equally glad to hire a consultant for a fee to get this resolved.
Thank you.
