Low latency is <strong>not</strong> always a feature you want to have. It
comes with a couple of drawbacks: the most prominent is increased power
consumption because the CPU needs to process many small chunks of audio data,
- it is constantly active and can not enter power-saving mode (think fan-noise).
+ it is constantly active and can not enter power-saving mode (think fan noise).
Since each application that is part of the signal chain must run in every
audio cycle, low-latency systems will undergo<dfn>context switches</dfn>
between applications more often, which incur a significant overhead.

compensate for latency in a DAW, <dfn>read-ahead</dfn> and
<dfn>write-behind</dfn>. The DAW starts playing a bit early (relative to
the playhead), so that when the sound arrives at the speakers a short time
later, it is exactly aligned with the material that is being recorded.

As you may see, the second approach is prone to various implementation
issues regarding timecode and transport synchronization. Ardour uses read-ahead
to compensate for latency. The time displayed in the Ardour clock corresponds
- to the audio-signal that you hear on the speakers (and is not where Ardour
