actionscript-3 - AS3 播放音频之间不必要的延迟

Question

我有一首歌被分成四段:前奏、A、B、结尾。我有一个播放前奏的程序，然后是 A 两次，然后 B 两次，然后再回到 A 并不断重复 AABB，直到我按下结束按钮。如果按下结尾按钮，则结束当前播放的歌曲片段，播放结尾并停止。它就像一个魅力，除了在歌曲之间的过渡中有一个非常明显的、令人讨厌的延迟。我怎样才能摆脱延迟，让它在前一段结束后立即播放歌曲？ (我在flash cs6中使用actionscript 3.0，歌曲为mp3格式，导入库中)。
这是程序:

这是我正在使用的代码:

import flash.events.MouseEvent;

stop();
//variables
var track_var: Number = 0;
var music_cnl:SoundChannel = new SoundChannel();
var intro_msc:Sound = new intro_mp3();
var a_msc:Sound = new A_mp3();
var b_msc:Sound = new B_mp3();
var outro_msc:Sound = new ending_mp3();
//stopping the movieclips
a_mc.stop();
b_mc.stop();
ending_btn.stop();

//intro
music_cnl = intro_msc.play();
track_var= 1;
intro_mc.gotoAndStop(2);
music_cnl.addEventListener(Event.SOUND_COMPLETE, playnext_fn);
trace("debug:track value set to",track_var);

//track selector
function playnext_fn(event:Event){
    trace("debug:playnext_fn called");
    switch(track_var){
        case 0:
            //stop
            music_cnl.stop();
            intro_mc.gotoAndStop(1);
            a_mc.gotoAndStop(1);

我没有看到您的代码有问题(除了关于
MAX_BUFFERSIZE，但我认为这看起来像是试图解决问题的残余!)

我认为更可能导致问题的是您的源音频 - 如果它作为 MP3 导入，或 with a bitrate of 48这可能会导致同步问题。
