与上一篇的“C++ 播放音频流(PCM裸流)” 点击打开链接 相对应，本篇是关于用C++实现录音功能的。同样是直接建一个win32控制台程序然后将代码拷过去改个文件名就可以用，也可以下载本人上传的相关工程，这个工程是用VS2013写的，如果是较低的版本就呵呵了。点击打开链接
代码部分如下：
- #include "stdafx.h"
- #include <stdio.h>
- #include <Windows.h>
- #pragma comment(lib, "winmm.lib")
-
- HWAVEIN hWaveIn;
- WAVEFORMATEX waveform;
- BYTE *pBuffer1;
- WAVEHDR wHdr1;
- FILE *pf;
- int _tmain(int argc, _TCHAR* argv[])
- {
- HANDLE wait;
- waveform.wFormatTag = WAVE_FORMAT_PCM;
- waveform.nSamplesPerSec = 8000;
- waveform.wBitsPerSample = 16;
- waveform.nChannels = 1;
- waveform.nAvgBytesPerSec = 16000;
- waveform.nBlockAlign = 2;
- waveform.cbSize = 0;
-
- wait = CreateEvent(NULL, 0, 0, NULL);
-
- waveInOpen(&hWaveIn, WAVE_MAPPER, &waveform,(DWORD_PTR)wait, 0L, CALLBACK_EVENT);
-
-
- DWORD bufsize = 1024*100;
- int i = 20;
- fopen_s(&pf, "录音测试.pcm", "wb");
- while (i--)
- {
- pBuffer1 = new BYTE[bufsize];
- wHdr1.lpData = (LPSTR)pBuffer1;
- wHdr1.dwBufferLength = bufsize;
- wHdr1.dwBytesRecorded = 0;
- wHdr1.dwUser = 0;
- wHdr1.dwFlags = 0;
- wHdr1.dwLoops = 1;
- waveInPrepareHeader(hWaveIn, &wHdr1, sizeof(WAVEHDR));
- waveInAddBuffer(hWaveIn, &wHdr1, sizeof (WAVEHDR));
- waveInStart(hWaveIn);
- Sleep(1000);
- waveInReset(hWaveIn);
- fwrite(pBuffer1, 1, wHdr1.dwBytesRecorded, pf);
- delete pBuffer1;
- printf("%ds ", i);
- }
- fclose(pf);
-
- waveInClose(hWaveIn);
- return 0;
- }
