In certain situations high latency on audio
Latency refers to the delay between when an audio signal enters a system and when it emerges. Excessive audio latency has the potential to degrade call quality.
Typical scenarios where latency might become an issue is:
- PA-Announcement where the operator hear his own announcement from nearby VoIP devices (e.g. IP Speakers or Intercoms)
- Systems with a mix of analogue and digital audio paths. Audio from the operator is distributed partly to main PA speakers through the analogue path, and partly to speakers via a digital (VoIP) path. The analogue path will have close to zero delay, while the digital path will have some delay. Too much delay it will resulting in an echo during announcements.
