MEDIA SERVER WITH SCALABLE STAGE FOR VOICE SIGNALS Russian patent published in 2023 - IPC H04L12/18 G06F3/16 H04M3/56 H04L65/403 

FIELD: means for audio communication.

SUBSTANCE: plurality of audio streams is received from a corresponding plurality of client devices. A plurality of audio streams is ranked based on a predetermined metric, wherein the metric for an audio stream includes a weighted frame energy of the audio stream. The weighted frame energy of an audio stream is determined using a weighting function that downplays content with a frequency spectrum below 1000 Hz and enhances content with a frequency spectrum above 4000 Hz. The first part of the plurality of audio streams is combined into a first group, wherein the first part of the plurality of audio streams represents N audio streams with the highest ranks. The second part of the plurality of audio streams is combined into a second group, wherein the second part of the plurality of audio streams represents M audio streams with the lowest ranks. Audio streams of the first group are redirected to the receiving device. Audio streams of the second group are deleted. N and M are independent integers.

EFFECT: increased efficiency of audio coding.
