get actual audio output level
Posted on 2010-09-02
how to programmatically sample the current level of audio output to the default sound card in windows? this is NOT a question about how to detect the volume i.e. it could be silent nothign coming out of the speakers, but the volume setting could still be high: the question is how to determine the actual output stream level sent to audio card, something that i imagine is used for VU meters or oscilloscopes in any media player application.
any help would be much appreciated, ideally for vb.net, but any other vs language is good too.
