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 10 RepliesI was wondering if there is an easy way to analyse sound that is sent to the speakers (just before it's played). For example when playing a song in winamp or windows media player. Or is it easier to write plugins for those programs to form an interface with your own program?

I am looking into programming an application that detects noise levels. If the level is over a specific threshold it will lock a logged on user account. The idea behind this application is to reduce noise levels in a busy IT suite. My question is has anyone written anything similar and did it prove to be effective and is VB the best programming language for the job?
View 1 RepliesI have seen similar questions which attempt to solve this issue, but none seem to work for me so far.Basically, for my first VB project, I am creating a virtual keyboard where a sound is played from the resources on KeyDown. So far, the program seems to work except for the fact that each key needs to be clicked by the mouse before the sound is played by pressing each key (hence put the object in focus), where I need the key to play the sound without clicking the keyboard key (put the object in focus on KeyDown).Below is an example of my code:

I need to get the decibel level of sound being sent to the sound card (not the actual sound level the speakers are instructed to emit via volume level)There is next to no information i can find on the net to even access sound data. Could anyone point me in a direction for this? The OS will be vista/7.

View 1 RepliesI 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.

View 1 RepliesI am having problems passing data from one form to another form opened from the first form.Here is my scenario: I have my start-up form. From this form I open a form by using the following:
[code]...
I use this because I want to be able to open multiple forms from the start-up form.Then from the PartyDetail form I open another form to display order details, like this:
[code]...
I want this order details form to be able to get a partyid variable from the party detail form.This works, but depending on the order that I open the forms the variables are incorrect Example:If I open the first PartyDetail form and then open the OrderDetail form, it works correctly. I can open as many PartyDetail and OrderDetail forms that I want and the variables are correct.But, say I open a PartyDetail form and then open another PartyDetail form and then open the OrderDetail form from the first opened PartyDetail form, it displays data based on the second opened PartyDetail form instead of the first. Basically, I want to be able to open multiple PartyDetail forms and then open OrderDetail forms based on whichever PartyDetail form it is opened from.Right now I am using Public Shared variables on the PartyDetail form and accessing this variable from the OrderDetail form. I suspect this is my main problem but don't know the best way to pass the variables from the PartyDetail form to the OrderDetail form.What would be the best way to do this?
Will any of the free light-weight charting libraries; ZedGraph or NPlot, be able to draw a simple graph similar to attached image (no waste of space, and with colored plot areas)? This plot will act much like the task manager "CPU Usage" plots, with update of last value every 500ms, but only making a new datapoint every 1 minute or so.
Or is this so extremely simple that it's better to hard-code it? What classes should I look into for this?

For i = 1 To 20
