Audio Delay Measurement

We first do a test OUTSIDE OF YOUR OFFICE TELEPHONE SYSTEM. It is a test of your conferencing system and the cellular providers conference attendees use. Our equipment is not used in any way.

The Baseline Test

Consider an audio test whereas:

  • person A says the word "TEA" to person B.
  • Person B repeats "TEA" back to person A.

Audio delay is introduced by

  • cell phone provider A
  • the audio conference system
  • cell phone provider B

Baseline Test Results

We have equipment that measures the audio delay of A speaking to B and B's response back to A. 

In the picture, it is the gap between waveform A and B. 5 samples are taken and averaged. This is the baseline delay.

The baseline delay value is the value we make better.

We Engineer to Reduce the Audio Delay

  • Replace your conference system with ours.
  • Optimize the path conference chairs use such as calling from our directly connected VoIP phone sets.
  • Educate parties to turn cellular HD calling and not use Bluetooth headsets that introduce added delay.

Why is Audio Delay a Problem?

In the days before the Internet, public phone networks ran at the speed of light. When you said something, the far end heard it almost immediately. This was the days of "switched audio" It was a reserved channel. Audio delay is a telecommunication issue created by the Internet and the move to "packet audio" aka (VoIP) Voice over IP.  

  • Cell phone providers moving to HD quality voice to conserve bandwidth
  • Conferencing systems that are poorly engineered or over capacity as in FREE systems
  • Remote parties joining via sub standard VoIP phone systems.
  • Remote parties using bad headsets and speakerphones.
