Hi I am trying to make a video game (undertale) in processing but I have come across some problems along the way. I am trying to import some mp3 files but when i start the program it says “INFO: JSyn: default output latency set to 80 msec for Windows 10”.

in order to make a good video game the default latency have to be as close to 0 as possible. If this can’t be done would it be nice to know if there an alternative way to use sound and have no latency.

- Those 2 are Linux distros w/ modified kernels for multimedia performance.
- I don’t think the Windows OS got any latency-less kernel version.
- In theory a user can set a task’s priority to real-time under Windows OS.
- However, I dunno whether an application can change that automatically or even it can ever reach actual 0 latency at all!

I am not sure, but this might be relevant:

@neilcsmith is really the expert on GStreamer-related questions.

I see that you have a related question posted here:
