Real-Time related information, articles, distributions, etc..
In an audio-related context, some kind of “real-time” is preferable, in order to gain low latencies. (Here, Latency is the time elapsed between audio-input and audio-output (including processing in between). )
The simplest way to obtain lower latency than usual, is to use an optimized linux audio distribution (see below). These generally utilize real-time patched kernels, with additional system optimisations, such as priority settings, etc.
