是否有可能记录由麦克风的终端用户？

Is it possible to record the end user by mic?

和我能做到与记录什么的孩子的行为？

And what kid of actions can I do with the recording?

我能获得例如声音的音量（分贝）的实时？

Can I get for example the volume of the sound (decibels) in real time?

我能保存该记录上的一个文件？

Can I save the record on a file?

感谢。

推荐答案

是的，Flash允许（与用户权限）的麦克风录制的能力。

Yes, Flash allows (with user permission) the ability to record from the microphone.

这是无数的网站，如Stickam如何合作，提供视频会议功能。

This is how countless sites like Stickam work to provide videoconferencing capability.

您不能承担的实际的（准确）的声音pressure的分贝读数 - 那就是声音pressure的绝对测量，将取决于百因素你无法控制的在用户的机器上（麦克风类型，位置，定位，修剪，频率响应，A / D转换，硬件COM pression等）。但是，你可以品尝到输入信号的的相对的幅度。

You cannot take actual (accurate) sound pressure readings in dB--that is an absolute measurement of sound pressure that would depend on a hundred factors you have no control of on the user's machine (mic type, location, positioning, trim, frequency response, A/D conversion, hardware compression, etc.). However, you can sample the relative amplitude of the incoming signal.
