FIELD: computer engineering.
SUBSTANCE: invention relates to computer engineering for processing audio data. Technical result is achieved due to stages, at which audiofilter is determined on the basis of discrete readings of reliable audio frame preceding lost audio frame; determining a modified audio filter based on said audio filter and generating a replacement frame based on the modified audio filter and discrete samples of the valid audio frame preceding the lost audio frame, wherein the step of determining the modified audiofilter includes narrowing the pass band.
EFFECT: high accuracy of masking frame loss for a low-frequency effects channel.
