Abstract

Даний спосіб включає в себе визначення, на основі рознесення між парами спектральних ліній (LSP), яке відповідає аудіосигналу, того, що аудіосигнал включає в себе компонент, який відповідає умові формування артефактів. Спосіб також включає в себе, у відповідь на визначення того, що аудіосигнал включає в себе згаданий компонент, регулювання параметра посилення, що відповідає аудіосигналу. Наприклад, параметр посилення може регулюватися через ослаблення посилення і/або згладжування посилення.
