In conferencing situations, it is quite possible that multiple microphones at different distances may gate on for a single person’s voice. Due to the delay time in traveling to the more distant mic, peaks and notches are created in the frequency response of the mixed signal called “comb filtering, “causing a hollow, distant feeling; like sound traveling through a tunnel.

 

This will reduce the intelligibility of voice transmitted to the far end during a conference call.

 

We at ClearOne deal with this problem in a unique way, by implementing our very effective First-Mic-Priority Algorithm to our Audio Conferencing solutions.

 

First-Mic Priority  helps maintain maximum audio intelligibility by allowing only one mic to gate on a participant’s voice. The algorithm does allow more than one microphone to be activated at same time— but it simply restricts mics from gating on to the same audio source. The first-mic priority feature evaluates each channel and  only allows the microphone with the loudest pickup to gate on.

 

If this feature is disabled, users will notice the undesirable effect of two or more microphones gate on when only one person speaks. Keeping the First-Mic Priority feature enabled in your mixer configuration which will translate into a cleaner pickup of voices with less “phasing” of the audio.
