FIELD: speech analysis or synthesis; speech recognition.
SUBSTANCE: invention relates to the field of audio signals encoding and decoding. Time scale converter for provision of the input audio signal time scaled version is configured to calculate or evaluate quality of produced by the input audio signal time scaling the input audio signal time scaled version. Time scale converter is configured to perform the input audio signal time scaling depending on the calculation or evaluation of produced by the time scaling the input audio signal time scaled version quality. Audio decoder contains such a time converter.
EFFECT: technical result is improvement in the input audio signal time-scaled version sound quality.
