录音到ＲＭＳ中，没有声音．．．

楼主kmlzkma（我去你妈）2005-05-22 11:16:08 在 Java / J2ME 提问

片段如下:

.....................　　　　　　　　　　　　　　
p = Manager.createPlayer("capture://audio");
p.realize();
rc = (RecordControl) p.getControl("RecordControl");
ByteArrayOutputStream output = new ByteArrayOutputStream();
rc.setRecordStream(output);
rc.startRecord();
p.start();
Thread.currentThread().sleep(3000);
p.stop();
byte b[] = output.toByteArray();
rs.open();
System.out.println(id = rs.addRecord(b, 0, b.length););
System.out.println("record sound end!");
rc.stopRecord();
rc.commit();
放音功能如下:
.............................
System.out.println("play is begin;");
InputStream is = new ByteArrayInputStream(rs.getRecord(id));
p = Manager.createPlayer(is, "audio/X-wav");
p.start();
System.out.println("play is end;");

为啥不好使呢?谢谢问题点数：100、回复次数：19Top

使用流进行播放应该没有问题的。

有更多的信息吗？Top

你的播放格式是audio/X-wav。首先要确定录音时存储的格式，多数手机默认是储存为amr的。Top

我不是放RMS里了么？还有格式么？

支持“yyworld() ”的观点，多数手机默认是储存为amr的。
有些时候存储方式为μ-law（由amr转换来的）Top
