问题描述

我要重新code中的声音时声音一定水平的接收和停止录音机不接收声音。

I want to recode the voice when certain level of sound receive and stop audio recorder does not receive sound.

我最初使用Media记录检查，当我得到它，然后我开始通过录音机录音，但我无法阻止它，因为录音机没有任何方法来获取最大振幅最大振幅。

I am initially using Media recorder to check maximum amplitude when I get it then I start recording via audio recorder but I am unable to stop it because audio recorder have not any method to get max amplitude.

推荐答案

您应该尝试一些像这样的事情：

You should try some thing like this:

readAudio = audioRecorder.read(data16bit, 0, buffer);
double fN = (double)readAudio;

double accum = 0;
for (int i = 0; i < readAudio; i ++)
{
   accum += Math.abs((double)data16bit[i]);
}

double soundLevel = accum/fN;

然后检查soundLevel的价值，看的时候应用程序应停止录制。

Then check the value of soundLevel to see when the app should stop recording.
