DSHOW reading volume levels

Dharma · 2002-02-04T23:21:37

Using Dshow: Is there any way I can read the amplitude of the sound being rendered? This data is ment to be used to create a vu-meter, EQ visual render etc etc. I''ve been looking for this but cant seem to find any source of information about it. If anyone just can point me out to a source I would appreciate it very much. Many thanks in advance. Mvh Mario.. Mvh Mario..

Sorry to bump this one like this.

If i understand your question correctly you're really only wanting the pan and volume ?????

if so, QI the IFilterGraph( or IGraphBuilder ) for IBasicAudio.

The docs explain it quite well.
