Audio processing for multi-participant communication systems

A trunk dispatch system, comprising:

• a plurality of trunk dispatch wireless ports through which audio is delivered to and received from a plurality of trunk dispatch participants, the audio from each trunk dispatch wireless port being prioritized and shared according to priority with the other trunk dispatch wireless ports of the plurality;
• a trunk dispatch processor that is in communication with the plurality of trunk dispatch wireless ports;
• and
• a non-transitory memory storing instructions which, when executed by the trunk dispatch processor cause the trunk dispatch processor to perform operations comprising:
• analyzing audio received from each of the plurality of trunk dispatch wireless ports to determine which trunk dispatch wireless ports are providing audio that includes characteristics matching at least one criterion by comparing a frequency, magnitude or duration of a sample of audio from each conference bridge port to a reference pattern of audio to determine a deviation from the reference pattern of audio of the frequency, the magnitude or the duration;
• associating a trunk dispatch participant among the plurality of trunk dispatch participants with each of the plurality of trunk dispatch wireless ports;
• determining a location of each of the trunk dispatch participants;
• and
• applying a correction to the audio from each of the trunk dispatch wireless ports that includes the characteristics matching the at least one criterion prior to the audio being shared with the other trunk dispatch wireless ports of the plurality, wherein the correction being applied by the trunk dispatch processor varies based on the trunk dispatch wireless port producing the audio being corrected, based on the trunk dispatch participant associated with the trunk dispatch wireless port producing the audio being corrected, and based on the location of the trunk dispatch participant associated with the trunk dispatch wireless port producing the audio being corrected;
• wherein the trunk dispatch processor applies the correction by muting and recording a period of audio from a first trunk dispatch wireless port when the audio from the first trunk dispatch wireless port overlaps with audio from a second trunk dispatch wireless port, and replaying the recording of the audio to the plurality of trunk dispatch wireless ports upon detecting an end to a period of audio from the second trunk dispatch wireless port.

A non-transitory computer readable medium containing instructions that, when executed by a processor, cause the processor to perform operations comprising:

• continually monitoring a plurality of ports of a multi-participant audio system, wherein each port of the plurality of ports is associated with a participant among a plurality of participants;
• analyzing the audio from each port to determine whether the audio from the ports matches at least one criterion by comparing a frequency, magnitude or duration of a sample of audio from each conference bridge port to a reference pattern of audio to determine a deviation from the reference pattern of audio of the frequency, the magnitude or the duration;
• determining a location of each of the participants;
• and
• when the audio from one of the ports matches the at least one criterion, then applying a correction to the audio prior to distribution of the audio within the multi-participant audio system, wherein the correction applied varies based on the port producing the audio being corrected, based on the participant associated with the port producing the audio being corrected, and based on the location of the participant associated with the port producing the audio being corrected and wherein the correction includes muting and recording a period of audio from a first port of the plurality of ports when the audio from the first port overlaps with audio from a second port of the plurality of ports, and replaying the recording of the audio to the plurality of ports upon detecting an end of a period of audio from the second port.
