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;
