OfflineAudioContext - 为多个频道添加收益

Question

我试图在OfflineAudioText中操纵各个缓冲区的增益。

交流和数据先前在

中加载后确定

 var source = ac.createBufferSource();
 source.buffer = data;
 var splitter = ac.createChannelSplitter(2);
 source.connect(splitter);
 var merger = ac.createChannelMerger(2);

 var gainNode = ac.createGain();
 gainNode.gain.value = 0.5;

 splitter.connect(gainNode, 0);
 splitter.connect(gainNode, 1);
 gainNode.connect(merger, 0, 1);
//error occurs here
 gainNode.connect(merger, 1, 0);

 var dest = ac.createMediaStreamDestination();
 merger.connect(dest);

错误：无法执行＆＃39; connect＆＃39; on＆＃39; AudioNode＆＃39 ;:输出索引（1）超过输出数量（1）

Answer 1

我没有正确分配输入：

splitter.connect（gainNode，0）; splitter.connect（gainNode，1）;

gainNode.connect（merger，0,0）; gainNode.connect（merger，0,1）;
