FIELD: computer technologies.
SUBSTANCE: invention relates to computer technology for processing audio data. The technical result is achieved on the basis of statistical relationships between the processed bin and at least one additional bin, information regarding the processed bin and at least one additional bin, statistical relationships and information regarding noise. The statistical relationships and information include a variance-related and / or standard deviation-related value provided based on variance-related and covariance-related relationships between the bins being processed and at least one additional context bin. The statistical relationships and information regarding noise include, for each bin, the highest value and the lowest value for evaluating the signal based on the expectation of the signal which must be between the highest value and the lowest value.
EFFECT: invention ensures reduction of noise when converting the estimated value of the processed bin into a time domain signal.
