Ask HN: Where can I find info on low-latency audio programming?

6 points by omginternets 10y ago ↗ HN

As a cognitive neuroscience grad student, I have a sudden need for low-latency audio stimulation. In short I have two needs:

1. I need to reduce jitter between programmatic audio playback and actual response in the headset. This is the biggest priority.

2. I need to reduce latency between the aforementioned systems.

3. I need to accurately track the time at which audio playback occurred.

Where can I learn more about this stuff? What basic vocabulary do I need to make relevant google queries?

And the raspberry pi wiki has info that if relevant for any linux audio hardware http://wiki.linuxaudio.org/wiki/raspberrypi

If you're coding for low latency not only do you need to tune your system you want to learn jackd and use jackd library for your app https://github.com/jackaudio/jackaudio.github.com/wiki

This looks like what I need. Many thanks!
