如何话筒获得声音输入的强度（非声卡输入音量设置）

swmp 2008-05-28 06:38:38

从网上找到一段代码，传说是微软的一个人写的，但调试不能通过，代码如下：
问题处用!!!标明了。



#include "stdafx.h"

#include <windows.h> 

#include <mmsystem.h> 



// 需要链接winmm.lib

// 希望获得声音输入的强度，而非声卡音量设置

int GetSoundIntensity()

{



       HMIXER hMixer;            // Mixer handle used in mixer API calls. 

       MIXERCONTROL mxc;         // Holds the mixer control data. 

       MIXERLINE mxl;            // Holds the mixer line data. 

       MIXERLINECONTROLS mxlc;   // Obtains the mixer control. 



       // Open the mixer. This opens the mixer with a deviceID of 0. If you 

       // have a single sound card/mixer, then this will open it. If you have 

       // multiple sound cards/mixers, the deviceIDs will be 0, 1, 2, and 

       // so on. 

       MMRESULT result = 0;              // Return code. 

	   result = mixerOpen(&hMixer, 0,0,0,0); 

       if (MMSYSERR_NOERROR != result) { 

           // Couldn't open the mixer.

		   return -1;

       } 



       // Initialize MIXERLINE structure. 

       ZeroMemory(&mxl,sizeof(mxl)); 

       mxl.cbStruct = sizeof(mxl); 



       // Specify the line you want to get. You are getting the input line 

       // here. If you want to get the output line, you need to use 

       // MIXERLINE_COMPONENTTYPE_SRC_WAVEOUT. 

	   // MIXERLINE_COMPONENTTYPE_SRC_MICROPHONE

       mxl.dwComponentType =  MIXERLINE_COMPONENTTYPE_DST_WAVEIN; 



       result = mixerGetLineInfo((HMIXEROBJ)hMixer, &mxl, 

                              MIXER_GETLINEINFOF_COMPONENTTYPE); 

       if (MMSYSERR_NOERROR != result) { 

           // Couldn't get the mixer line. 

           mixerClose (hMixer);

		   return -1;

       } 



       // Get the control. 

       ZeroMemory(&mxlc, sizeof(mxlc)); 

       mxlc.cbStruct = sizeof(mxlc); 

       mxlc.dwLineID = mxl.dwLineID; 

	   // !!!!!!此处应该是MIXERCONTROL_CONTROLTYPE_PEAKMETER，但是调用mixerGetLineControls不能通过

       mxlc.dwControlType = MIXERCONTROL_CONTROLTYPE_MIXER;//MIXERCONTROL_CONTROLTYPE_PEAKMETER; 

       mxlc.cControls = 1; 

       mxlc.cbmxctrl = sizeof(mxc); 

       mxlc.pamxctrl = &mxc; 



       result = mixerGetLineControls((HMIXEROBJ)hMixer,&mxlc, 

                                  MIXER_GETLINECONTROLSF_ONEBYTYPE|MIXER_OBJECTF_HMIXER); 

       if (MMSYSERR_NOERROR != result) 

	   { 

		   // !!!!! 使用MIXERCONTROL_CONTROLTYPE_MIXER不能成功

		   // Couldn't get the control. 

		   // Get the control. Try Mux

			ZeroMemory(&mxlc, sizeof(mxlc)); 

			mxlc.cbStruct = sizeof(mxlc); 

			mxlc.dwLineID = mxl.dwLineID; 

			mxlc.dwControlType = MIXERCONTROL_CONTROLTYPE_MUX;//MIXERCONTROL_CONTROLTYPE_PEAKMETER; 

			mxlc.cControls = 1; 

			mxlc.cbmxctrl = sizeof(mxc); 

			mxlc.pamxctrl = &mxc; 

			// 此处调用成功

			result = mixerGetLineControls((HMIXEROBJ)hMixer,&mxlc, 

										MIXER_GETLINECONTROLSF_ONEBYTYPE|MIXER_OBJECTF_HMIXER); 

			if (MMSYSERR_NOERROR != result)

			{

				mixerClose (hMixer);

				return -1;

			}

       } 



       // After successfully getting the peakmeter control, the volume range 

       // will be specified by mxc.Bounds.lMinimum to mxc.Bounds.lMaximum. 



       MIXERCONTROLDETAILS mxcd;             // Gets the control values. 

       MIXERCONTROLDETAILS_SIGNED volStruct; // Gets the control values. 

       long volume;                          // Holds the final volume value. 



       // Initialize the MIXERCONTROLDETAILS structure 

       ZeroMemory(&mxcd, sizeof(mxcd)); 

       mxcd.cbStruct = sizeof(mxcd); 

       mxcd.cbDetails = sizeof(volStruct); 

       mxcd.dwControlID = mxc.dwControlID; 

       mxcd.paDetails = &volStruct; 

       mxcd.cChannels = 1; 



       // Get the current value of the peakmeter control.  

	   // !!!!!此处参数错误，可能是因为前面使用了MIXERCONTROL_CONTROLTYPE_MUX的原因

       result = mixerGetControlDetails((HMIXEROBJ)hMixer, &mxcd, 

                                    MIXER_GETCONTROLDETAILSF_VALUE); 

       if (MMSYSERR_NOERROR != result) { 

           // Couldn't get the current volume.

		   mixerClose (hMixer);

		   return -1;

       } 

       volume = volStruct.lValue; 

	   return volume;

}



还有一种说法是通过wavein数据转换成声音强度，但没有例子，有没有DX知道

谢谢

我插句话，
不就是声音的频谱分析嘛
源码很多
然后比较数字量的大小

lz google一下
