用waveOutSetPlaybackRate似乎可以调整,但运行之后没有任何反应。

Remarks
Changing the playback ratedo
es not change the sample rate butdo
es
change the playback time. Not all devices support playback rate changes.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
To determine whether a device supports playback rate changes, use the
WAVECAPS_PLAYBACKRATE flag to test the dwSupport member of the WAVEOUTCAPS
structure (filled by the waveOutGetDevCaps function).
---------------------------------------------------------------------
但我记得Winamp有一个插件可以调整播放WAV文件的速率,而且不受设备限制,
不知哪位大虾有这方面的资料,或者实现代码,或者控件,望不吝赐教。
