I'm currently trying to get around developing an application that will alert me when process X is using my sound card.

View 2 RepliesIs it possible to capture the raw signal from a WiFi card in the same way you can capture the signal from a sound card? (I already found code for working with a sound card and for drawing spectrograms) I'm wondering because it would make a cool radio-type project. I'd prefer a solution that integerates well with .net (VB or C#).My basic goal is to capture the ambient radio waves and build a primative "telescope" of sorts. Using the built in computer hardware is just the easiest way to accomplish this. If you have any other suggestions about how to accomplish this goal in a different way please post it as an answer also.
View 1 RepliesI am trying to write a countdown timer I finally succeeded with MSDN. I get to work whatever I wanted, but this drives me nuts: How can I read and set the volume control? I want, once my timer is run down to zero, read out the current system setting, then play a system sound using
Media.SystemSounds.Exclamation.Play()
Over time I like to ramp up the volume to 80% or until one clicks the Alarm off button (then stop the timer, no sound, and reset volume).
get data like the pitch and volume of the sound currently being "heard" through a microphone?
Do you know the little graph which the Windows 98/XP sound recorder used to show? It used to show the pitch and volume of the sound which was being recorded. Like I want to get the data from that.
Basically, I will start experimenting this stuff by showing the volume of the sound entering the microphone in a label. And maybe the pitch too.
I need a way of recording any sound that is played through the computer so say if the user was open up windows media player and play a song then he could click record on my application and it would capture whatever is being played. After that there would also need to be a save button so the can click save and the user can save the file as a .wav or .mp3 or whatever!
View 6 RepliesI 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 6 RepliesIs there a way to generate a pure tone (e.g. 440 Hz) for a specified period of time through the sound card without using having to find or make a separate .wav file for each tone.I tried using the "Beep" function, but while it produces the tone for a specified period, it sounds broken up into a (probably 500ms) time frame which repeats with an audible space between the repetitions.

Can I monitor the registry for changes similar to how sysinternals process monitor does it in VB? I have checked many different articles and C# samples but not come any closer to getting an answer, I would like to know if there an easier way (a VB sample perhaps)that you folks can share. Ultimately I'd like to be able monitor other things too like file system, processes etc but wonder most about how the registry can be done in VB...Would using system.management be a start? Or WMI? if so is there a nice VB sample..

Does anyone know how to get and set the system sound volume? I have tried every method I've found on the net and none of them work. I've tried the winmm.dll APIs with no luck. I've also tried waveOutGetVolume/waveOutSetVolume, which didn't work. I'm using Win 7, but need a solution that works on XP+.
Right now I use the VolumeUp keyboard event, but I need to be able to get the volume and set it to a specific level.
Maby ive been going about this the wrong way. Im attempting to change the system volume using VB.net. I dont want to use the mediaplayer stuff because i dont want that to be open the whole time. if someone could point me to a working API or something for changing system volume and getting the current volume id be great full! plus.

View 2 RepliesI would like to be able to measure the frequency of a sine wave applied to the input of a "standard" Windows sound card system.I need to do this in near real-time (not by analyzing a wav file after the event) and I need to continuously measure every half-cycle of audio and store the results in some kind of buffer that I can read into a VB app. I have tried googling for this and it seems to be a very popular question but I have not found any really good answers. Does anyone know of a DLL that could do this? I wouldn't mind paying a reasonable sum for a commercial DLL if there is such a thing.
Another related requirement is to generate sine-waves - again this must be done in near real-time and it must be possible to change each half-cylce of the waveform. For example,I might need to generate a few half-cycles of 1500 Hz to be followed (with no break in the waveform) by half-a-cycle of 2300 Hz.

View 1 RepliesSecond, I have a question which I have been trying to find answer for a wile but without any success.How can I monitor Windows Process for any change (create/kill) after run my app ? the only way I have think about it is that used two lists, the first one load the process list on it and the second refresh each 1 sec to get the new one and compare the two to know the difference, but its useless because you cant know who killed or created the process and other information.
As I have been read before, I guess there is a need to implement windows API, hook to detect process changes ? Is there any idea or solution for this?

I dont want to write logs out to a file and use filesystemwatcher to monitor for changes.
