WASAPI Initialize支持的采样率是多少 [英] What are supported sample rates for WASAPI Initialize

问题描述

嗨....

MSDN（ http://msdn.microsoft.com/en-us/library/windows/desktop/dd390970(v = vs.85）.aspx） 在下面说PCM支持采样率

MSDN (http://msdn.microsoft.com/en-us/library/windows/desktop/dd390970(v=vs.85).aspx) says below sample rates are supported for PCM

"如果 wFormatTag 为WAVE_FORMAT_PCM，那么
nSamplesPerSec 的常用值为8.0 kHz ，11.025 kHz，22.05 kHz和44.1 kHz。 "

"If wFormatTag is WAVE_FORMAT_PCM, then common values for nSamplesPerSec are 8.0 kHz, 11.025 kHz, 22.05 kHz, and 44.1 kHz. "

当我尝试以下代码时，采样率为8.0kHz，初始化返回0x88890008

When I tried the below code, with sample rate 8.0kHz,  Initialize returns 0x88890008

11.025 kHz，22.05 kHz和44.1 kHz也会出错!!

11.025 kHz, 22.05 kHz, and 44.1 kHz also gives error!!

只有48 KHz对我有用..请帮我理解这个场景。

Only 48 KHz is working for me..Please help me to understand the scenario.

m_MixFormat->nSamplesPerSec = 8000;
m_MixFormat->wFormatTag = WAVE_FORMAT_PCM;
m_MixFormat->wBitsPerSample = 16;
MixFormat->nBlockAlign = m_MixFormat->nChannels * 2;    
m_MixFormat->nAvgBytesPerSec = m_MixFormat->nSamplesPerSec * m_MixFormat->nBlockAlign;
m_MixFormat->cbSize = 0;

     
hr = m_AudioClient->Initialize( AUDCLNT_SHAREMODE_SHARED,
                                        AUDCLNT_STREAMFLAGS_EVENTCALLBACK,
                           200000,
                           0,
                           m_MixFormat,
                           nullptr );

谢谢。
