Latency
Latency is the delay between when audio is sent from the program and when you actually hear it. While a very low latency can be crucial in a real-time DAW application such as Steinberg Nuendo or Cubase, this is not strictly the case with WaveLab Elements.
When working with WaveLab Elements, the important issues are optimum and stable playback and editing precision.
The latency in an audio system depends on the audio hardware, its drivers, and settings. In case of dropouts, crackles, or glitches during playback, raise the Buffer Number setting on the Options tab in the Audio Connections, or increase the buffer size in the ASIO control panel, specific to the audio card.
