Adobe Flash 从麦克风录制压缩样本
我想从 adobe AIR 应用程序中的麦克风捕获音频样本，然后将它们保存到 flv 文件中。我有以下代码：
mic.setSilenceLevel(0, DELAY_LENGTH);
mic.codec = SoundCodec.SPEEX;
mic.encodeQuality = 6;
mic.framesPerPacket = 1;
mic.gain = 100;
mic.addEventListener(SampleDataEvent.SAMPLE_DATA, micSampleDataHandler);
问题是我怀疑在我的处理程序中我只获取原始样本而不是压缩样本。我怀疑的原因是，我获得的每条消息的字节数等于 20 毫秒（我的定义是 1 speex 帧）的原始音频而不是压缩音频。如果我更改encodeQuality，字节数也不会改变。阅读文档表明 adobe 只会在传输到闪存媒体服务器或其他对等点之前压缩音频。有没有办法在本地发布和读取流以获得压缩样本。 ？或者还有其他方法来获取压缩样本吗？
I want to capture audio samples from the microphone in my adobe AIR application and then save them to an flv file. I have the following code:
mic.setSilenceLevel(0, DELAY_LENGTH);
mic.codec = SoundCodec.SPEEX;
mic.encodeQuality = 6;
mic.framesPerPacket = 1;
mic.gain = 100;
mic.addEventListener(SampleDataEvent.SAMPLE_DATA, micSampleDataHandler);
The problem is that I suspect that in my handler I am only getting raw samples and not compressed samples. The reason for my suspicion is that the number of bytes I get per message is equal to 20 ms (which my definition is 1 speex frame) of raw audio and not compressed audio. Also the number of bytes doesnt change if I change the encodeQuality. Reading the documentation suggests that adobe will only compress the audio before transmission to a flash media server or another peer. Is there a way to publish and read the stream locally in order to get compressed samples.
? Or any other way to get the compressed samples?

您可以使用以下命令将录音编码为 mp3
http://code.google.com/p/flash-kikko/
然后保存文件某处，以便您可以将其合并到 flv 中。
You can encode your recording as mp3 using
http://code.google.com/p/flash-kikko/
Then save the file somewhere so you can incorporate that into an flv.
