    ActiveX control for webcam microphone

    an ActiveX control or extension for getting both volume levels of a usb webcam microphone at intervals lower than 40 miliseconds and the webcam's image capture (both at realtime) as a bitmap. I believe this will lead to high quality open source speech recognition

    vote it up !

    Hi Moti,

    Still looking for that?
    Take a look in XNA.
    Some places to start:

    starting with the volume meter of the 2nd link it doesn't cut the mustard :

    1 it actually gets the volume meter at something like 150 - 200 miliseconds
    not at all good to carry speech reco algorithms.

    2 it has a second problem : it doesnot work with the vb.net webcam image
    capture at the same time, major problem

    3 after testing it didn't work at vb.net 2010 .net framework 4.0

    Re: ActiveX control for webcam microphone

    as for the 1st of your links, I am talking about a vb.net volume meter.

    this is a golden opportunity for many programmers, a chance that might not return, not only can the volume meter described in post #1 be used for speech reco, but also for many applications :
    security, robotics, interactive games... all sorts of stuff that were off limits.

    maybe the line
    vote it up !
    looks rude, I actually tried to convey exitment.

    I don't know men, at least I tried, no regrets for me, do what you want.
    maybe MS will see the value of such a volume meter, thanks for taking the time to read my post.
    and again a special thanks to doug who is very cool.

    The first link gives a demo how to use a microphone in XNA. The samples are in a byte array.

    In the second link a sample is shown how to create a VU-meter in dB from a byte array.

    Not sure what the reaction speed of a VU-meter has to do with speech reconition.

    Don't forget that MS is moving sound and vision to DirectX (XNA). So not sure what you mean by "the vb.net webcam image capture". At the end its just an array of bytes.
