I would like to create a visualizer for the windows system audio. I'm looking for a way to sample the loudness of the sound currently being played. I don't need the actual sound unless required for computing the sound levels. My goal is to create something similar to the bouncing green level found on windows 7's volume control.

It seems like this would be a very easy thing to accomplish, but, from what I can tell, it's most definitely not. My OS is Windows 7. All I need to do is get the current volume/audio level - the master volume. When you click the little speaker icon in the task bar and change the volume - I need that number. All I need to do is get the current volume and assign it to a label. So if the volume is at 74 when the application starts, I need my label to display 74. I've been searching for days now for a way to do this and I'm starting to get frustrated. I've looked everywhere. I've tried 3 different classes, at least a dozen different codes, assorted imported dll's- none of it even came close to what I need. From what I can tell, the current methods are all designed for windows xp. I need a way to do it in windows 7.

View 6 RepliesI am looking to be able to do life frequency detection in VB.net. I must say I don't really know where to begin here. I have looked into BASS.net, but that seems to only work with pre-recorded audio. I need to be able to detect the frequency of audio coming in over the line in or mic input in near real-time.

View 2 RepliesI'm pretty new to VB and I chose a project for school to recognise the pitch/note of a sound comming from my microphone (Which I'm using singular notes using my Guitar). I have no idea if this is even possible :/ So if possible, what things should I be considering and what I pretty much need to do to get the ball rolling for me

View 2 RepliesIs there any way to adjust master audio volume directly using .net?
I can find C++ coding which, sadly means nothing to me. There's also quite a lot out there for VB4, 5 and 6 but I can't get any of that to relate to .net. Most of those seem to want to invoke the 'Slider' via the mouse which is not what I'm after.
I would like to be able to: -
Record the current Audio Volume setting,
Change it (up or down),
Play a *.wav file, then
Return it to it's original level.
I've had some success with 'AxWindowsMediaPlayer' but only with it's own increase / decrease functions. I can only get it to increase the volume as far as the main system volume is set, so if that's at zero I get no output at all. As for part one of my requirement, record the current level, I've got nowhere with that at all. I tried putting the one file I want to use in resources but can't find how to access it, I have had to put the file in a folder and call it from there, it works but it seems a little crude.

I was just thinking if there is any component which monitors sound output. My intention is to recognize a particular sound coming out from my soundcard. I know its an issue about the driver of my sound card but is there a way I can get atleast noise level coming out of my speakers and maybe draw a graph and detect the peak at when the sound is played?

View 7 RepliesI have a database application developed around Access with VBA,I have used the Speech SDK and developed an application that in conjunction with MSCOMM 6.0 library calls into a remote IVR system.It sends in the credentials and queries information in response to that IVR's verbal requests. All seems successfull except for one problem;I'm using a shared SR engine and its using the system microphone as its audio input, this in turn gets the sound from the speakers which are routed to the telephone line through the modem. Of course this has a number of disadvantages - noise added to the sound from the environment and sound quality degredation as well as speaker volume dependency.
I would like the SR engine to take its audio input from the modem in paralell with the sound that goes to the speakers (so we can listen in to the call as well). This means that I must route the system audio output to the SR engine audio input. It seems that I must use an InProc SR instance - however in VBA that type is not recognized - since the shared SR uses the microphone as input by default. there is some statement to the effect that it is difficult in Microsoft's Help file. I'm unable to set the SR audio input to the modem output stream in VBA.As needed I can accomplish the C++ interface using an ActiveX object or a DLL to expose the missing API to VBA?

I've tried a few alternative libs such as DirectShow.Net, DirectSound, BASS.Net, QuickTime and OpenTK.Some of them do what I need to do, but they are either too difficult to use and therefore impractical or they are missing some other essential features such as Events which are required to make the rest of the application work.
