推荐答案

可以使用 Microphone API SAMPLE_DATA 事件录制音频.事件的 data 属性是一个带有音频数据的 ByteArray.

It is possible to record audio using the Microphone API SAMPLE_DATA event. The data property of the event is a ByteArray with the audio data.

基于 Web 的 Flash 应用程序可以将这些数据样本复制到内存中的数据结构，并提示用户将数据保存到本地文件.AIR 应用程序将能够将数据直接写入文件系统或 SQL 数据库.

A web based Flash application could copy these data samples to a data structure in memory and prompt the user to save the data to a local file. An AIR application would be able to write the data to the file system or SQL database directly.

有关在 ActionScript 中访问来自麦克风的音频，请参阅以下链接:

以标准化格式对数据进行编码可能有助于以后阅读和编辑(WAVa> 或 PCM).您可能还想使用压缩来减小传输文件的大小(例如:Ogg Vorbis来自 Adob​​e 的编解码器).

It may help to encode the data in a standardised format to help with reading and editing later (WAV or PCM). You may also want to use compression to reduce the file size for transmission (eg: Ogg Vorbis codec from Adobe).
