Monitoring and maintaining signal quality for each participant of a group call

A computer program product (CPP), comprising:

• a set of one or more computer readable storage media;
• and
• program instructions, collectively stored in the set of one or more storage media, for causing a processor set to perform computer operations including:
• receive a source audio signal from a speaker on a group call between the speaker and participants;
• receive copies of resulting audio signals from the participants, the copies of the resulting audio signals including unique versions of the source audio signal as received by the respective participants;
• determine an amount of the source audio signal received by the respective participants by comparing the source audio signal with the respective copies of the resulting audio signals;
• and
• output statuses to the speaker, the statuses being correlated with the amount of the source audio signal received by the respective participants by:
• dynamically combining the statuses, correlated with the amount of the source audio signal received by the respective participants, into a summary,
• causing the summary to be displayed in real-time on a user interface corresponding to the speaker, and
• dynamically updating the summary as the statuses change over time.

A computer system (CS), comprising:

• a processor set;
• a set of one or more computer readable storage media;
• program instructions, collectively stored in the set of one or more computer readable storage media, for causing the processor set to perform computer operations including:
• receive a source audio signal from a speaker on a group call between the speaker and participants;
• receive copies of resulting audio signals from the participants, the copies of the resulting audio signals including unique versions of the source audio signal as received by the respective participants;
• determine an amount of the source audio signal received by the respective participants by comparing the source audio signal with the respective copies of the resulting audio signals;
• output statuses to the speaker, the statuses being correlated with the amount of the source audio signal received by the respective participants;
• and
• in response to determining the amount of the source audio signal received by a given participant is outside a predetermined range:
• identify portions of the source audio signal that are absent from the copy of the resulting audio signal received by the given participant;
• resend the identified portions of the source audio signal to the given participant;
• cause the identified portions of the source audio signal to replace the corresponding portions of the resulting audio signal received by the given participant;
• and
• cause a logical button to be displayed on a user interface corresponding to the given participant, the logical button being configured to initiate replaying the identified portions of the source audio signal in response to the logical button being activated.
