Ask HN: Where can I find info on low-latency audio programming?
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?
- shams93 11y agoArch has a lot of good info https://wiki.archlinux.org/index.php/Pro_Audio https://wiki.archlinux.org/index.php/Pro_Audio And the raspberry pi wiki has info that if relevant for any linux audio hardware http://wiki.linuxaudio.org/wiki/raspberrypi http://wiki.linuxaudio.org/wiki/raspberrypi
- shams93 11y agoIf 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 https://github.com/jackaudio/jackaudio.github.com/wiki
