本文介绍了怎么把pcm16转换成pcm8?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
WAVEFORMATEX in_wfx;
in_wfx.wFormatTag = WAVE_FORMAT_PCM;
in_wfx.nChannels =1;
in_wfx.nSamplesPerSec =8000;
in_wfx.nAvgBytesPerSec =16000;
in_wfx.nBlockAlign =2;
in_wfx.wBitsPerSample =16;
in_wfx.cbSize = 0;
如何将上述形式转换为波纹管形式?
how to convert above form to bellow form?
WAVEFORMATEX out_wfx;
out_wfx.wFormatTag = WAVE_FORMAT_PCM;
out_wfx.nChannels =1;
out_wfx.nSamplesPerSec =8000;
out_wfx.nAvgBytesPerSec =8000;
out_wfx.nBlockAlign =1;
out_wfx.wBitsPerSample =8;
out_wfx.cbSize = 0;
推荐答案
亲爱的，
在这种情况下，您必须删除16位PCM样本的低字节.这也与endian有关.
Dear,
In this case, you have to drop lower byte of 16bit PCM sample. Also this is related with endian.
