Method and system for full duplex enhanced audio

A device comprising:

• a microphone;
• a speaker;
• a communication interface;
• a memory, wherein the memory stores instructions;
• and
• a processor, wherein the processor executes the instructions to:
• store high pass filter values and compression values;
• store target audio values including a target echo return loss enhancement value and a target total harmonic distortion value;
• establish, via the communication interface, a full duplex voice communication session with another device;
• generate, during the full duplex voice communication session, an echo coupled reference signal, an echo feedback reference signal, an echo return loss enhancement signal, and a first downlink signal;
• generate, during the full duplex voice communication session, a second downlink signal based on the echo coupled reference signal, the echo feedback reference signal, the echo return loss enhancement signal, the first downlink signal, the high pass filter and compression values, and the target audio values;
• produce, by the speaker during the full duplex voice communication session, sound based on the second downlink signal;
• reduce a first gain of a first echo coupled signal in an uplink path based on a first threshold value, wherein the first threshold value is based on a gain attributed to echo coupling;
• and
• increase a second gain of a second echo coupled signal in the uplink path based on the first threshold value.

A non-transitory, computer-readable storage medium storing instructions executable by a processor of a device, wherein the instructions comprise instructions to:

• store high pass filter values and compression values;
• store target audio values including a target echo return loss enhancement value and a target total harmonic distortion value;
• establish a full duplex voice communication session with another device;
• generate, during the full duplex voice communication session, an echo coupled reference signal, an echo feedback reference signal, an echo return loss enhancement signal, and a first downlink signal;
• generate, during the full duplex voice communication session, a second downlink signal based on the echo coupled reference signal, the echo feedback reference signal, the echo return loss enhancement signal, the first downlink signal, the high pass filter and compression values, and the target audio values;
• produce, by a speaker of the device during the full duplex voice communication session, sound based on the second downlink signal;
• reduce a first gain of a first echo coupled signal in an uplink path based on a first threshold value, wherein the first threshold value is based on a gain attributed to echo coupling;
• and
• increase a second gain of a second echo coupled signal in the uplink path based on the first threshold value.
