How to use WASAPI or DirectSound as sound input

Apr 22, 2013 at 7:09 PM
I' trying to use another form of input (WASAPI or DirectSound) but I'm not getting properly.
In class WaveIn properties BufferMiliseconds and NumberOfBuffers exist, however in others there is no such property.
Has anyone successfully used these classes ?
The reason for using it is because with them with a unique key (Guid) for each sound card, unlike WaveIn class.
