问：其中承担是最好的？ 答：黑熊

Question: Which bear is best? Answer: Black Bear

虽然严重，则需要说明你的标准音频文件，我们做出一个codeC的建议。是否需要可移植？最佳COM pression？最高保真度的？

Seriously though, you would need to state your criteria for the audio file for us to make a codec recommendation. Does it need to be portable? Best compression? Highest fidelity?

您选择了没有音频的的响度的将播放在设备的影响，所以这不应该析因入您的标准。在codeC

The codec that you choose has no affect on the loudness of audio that will be played over the device, so this should not factor into your criteria.

有增加声音的另一种方式？ 是的，如果你是从麦克风录制声音，那么你可以将它保存到一个文件之前放大音频数据。

Is there an alternative way to increase audio? Yes, if you are recording audio from the microphone then you can amplify the audio data before you save it to a file.

让来自麦克风的音频样本进行重新的功能psented $ P $：

Let an audio sample from the microphone be represented by the function:

f(t)

放大由音频样本被一些因素乘法实现了。

Amplification is achieved by multiplying the audio sample by some factor A

A * f(t)
