不知道编码器保存声音ByteArray的FLV，但micRecord库（http://code.google.com/p/ micrecorder /）有wav编码器。尝试一下。 – Art 2012-04-20 13:48:17

@Art：我的问题主要是关于保存文件而不是格式。如何在录制文件后保存文件。 – Rajeev 2012-04-20 14:18:56

@Rajeev通常，在课程中发布相同问题的三个版本通常不被认为是好的礼仪两天。 – JeffryHouser 2012-04-20 15:26:30

这是你更新的代码，将提供您能力保存文件中记录后保存。但无论如何，你需要编码的ByteArray到像WAV或MP3格式：

        file.save(/*You need encoded soundBytes here*/soundBytes ,"Testsound.wav");
