A method for reducing computational complexity of participants in a conference communication setting through recognition and elimination of redundant encoding of signals, wherein said method comprises the steps of: a. receiving audio for participants to the conference communication setting by a means for signal processing (110, 205); b. determining a contributing state or a non-contributing state for each participant, by the means for signal processing using a voice activity detection, wherein each participant is assigned a contributing state or a non-contributing state; c. processing, by a conference system, said audio to generate return audio for each participant (215, 220, 230), wherein improvements to said processing comprises: i. recognizing non-contributing participants that are receiving similar audio having similar audio encoding formats; ii. removing redundant audio from the similar audio for the non-contributing participants; iii. associating contributing and non-contributing participants with an encoder instance; and iv. encoding said similar audio with removal redundant audio for the non-contributing participants having similar attributes by a single shared encoder instance to eliminate redundant encoding and to generate said return audio; and d. transmitting, by the conference system, said return audio to said participants, wherein said non-contributing participants having similar attributes receive the return audio with eliminated redundant encoding of signals. a. receiving audio for participants to the conference communication setting by a means for signal processing (110, 205); b. determining a contributing state or a non-contributing state for each participant, by the means for signal processing using a voice activity detection, wherein each participant is assigned a contributing state or a non-contributing state; c. processing, by a conference system, said audio to generate return audio for each participant (215, 220, 230), wherein improvements to said processing comprises: i. recognizing non-contributing participants that are receiving similar audio having similar audio encoding formats; ii. removing redundant audio from the similar audio for the non-contributing participants; iii. associating contributing and non-contributing participants with an encoder instance; and iv. encoding said similar audio with removal redundant audio for the non-contributing participants having similar attributes by a single shared encoder instance to eliminate redundant encoding and to generate said return audio; and i. recognizing non-contributing participants that are receiving similar audio having similar audio encoding formats; ii. removing redundant audio from the similar audio for the non-contributing participants; iii. associating contributing and non-contributing participants with an encoder instance; and iv. encoding said similar audio with removal redundant audio for the non-contributing participants having similar attributes by a single shared encoder instance to eliminate redundant encoding and to generate said return audio; and d. transmitting, by the conference system, said return audio to said participants, wherein said non-contributing participants having similar attributes receive the return audio with eliminated redundant encoding of signals.
