关于g723.1语音编解码问题？

Question

有那位仁兄有这方面的源代码能否给小弟提供，给小弟讲解讲解。我有一个g723.1的源代码，可是看不懂有那位高手能帮忙。感激不尽。

Answer 1

//压缩音频帧
BOOL CCodecMgr::EncodeAudioData(char  *pin,int len,char * pout,int* lenr)
{
BOOL bRet=FALSE;
if(!pin||len!=SIZE_AUDIO_FRAME||!pout)
goto RET;

va_g729a_encoder((short*)pin,(BYTE*)pout);
va_g729a_encoder((short*)(pin+160),(BYTE*)pout+10);
va_g729a_encoder((short*)(pin+320),(BYTE*)pout+20);
va_g729a_encoder((short*)(pin+480),(BYTE*)pout+30);
va_g729a_encoder((short*)(pin+640),(BYTE*)pout+40);
va_g729a_encoder((short*)(pin+800),(BYTE*)pout+50); //FOR DEBUG
//pout = pin; if(lenr)
*lenr=SIZE_AUDIO_PACKED; bRet=TRUE;
RET:
return bRet;
}
//解压缩音频帧
BOOL CCodecMgr::DecodeAudioData(char  *pin,int len,char * pout,int* lenr)
{

BOOL bRet=FALSE;
if(!pin||len!=SIZE_AUDIO_PACKED||!pout)
goto RET; va_g729a_decoder((BYTE*)pin,(short*)(pout),0);
va_g729a_decoder((BYTE*)pin+10,(short*)(pout+160),0);
va_g729a_decoder((BYTE*)pin+20,(short*)(pout+320),0);
va_g729a_decoder((BYTE*)pin+30,(short*)(pout+480),0);
va_g729a_decoder((BYTE*)pin+40,(short*)(pout+640),0);
va_g729a_decoder((BYTE*)pin+50,(short*)(pout+800),0); if(lenr)
*lenr=SIZE_AUDIO_FRAME;

bRet=TRUE;
RET:
return bRet;
}
