In perceptual audio coding with low bitrate application, the pre-echo artifact is more distinct, and the effective detection of transient signals is the precondition.
在低比特率音频感觉编码中,预回声失真更为突出,而对其处理的前提是瞬态信号的有效检测。

Auailable BitRate (ABR) Service can make most effective use of ATM networks resources. LANS can achieve interworking of high throughput and low loss through WAN as well.
业务可以提高AT M网络的利用率,能让用户LAN通过广域网进行高吞吐量、低丢失率的互通。

The experiment results showed that the improved methods were simple and effective, it could decrease rate of bit and time of coding.
