摘要: A transient echo can be avoided during time stretching of a digital audio signal by detecting in frame signal, identifying another occurrence the subsequent rotating occurring to align with detected frame, and aggregating frame. Further, identified it determined that cannot aligned The copy then blended across such as performing phase accumulation on one or more frequency components.
