我这边在使用框架的时候，发现有些设备的收音推流出去的声音音量特别小，即使设备声音开到最大也还是比较小，请问作者或者同行有遇到的并且有解决方案的分享一下解决办法，谢谢

不太明白你说的“收音”是啥意思，是麦克风采集吗？这个可以把pcm保存到本地文件来定位，是否设备本身的问题

表述错误，我想表达的是使用RTMP推流时有些推流设备推出流的声音特别小，我测试设备是华为平板，有没有方法将声音放大

每个PCM样本去乘上一个因子试试，你先本地把采集的PCM样本保存为文件看看是否真的声音很小

我这边音视频技术不太好，您能给指导一下在哪改吗？有代码截图更好

怎么改算是增加因子？

乘上一个数，当然效果不一定好，关键看你的设备采集，自己研究吧
