Is 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.

View 2 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 1 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 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.
I'm currently trying to get around developing an application that will alert me when process X is using my sound card.
View 2 RepliesI 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 1 RepliesI'm creating an application that will have 3 streams of audio. I can get 2 streams playing easy enough using DirectX AudioVideoPlayback and setting the balance for each Audio Instance. However, I need a 3rd Audio instance to play out of another output such as the Rear or Centre. An alternative would be to be able to select a different sound device in the machine to play the 3rd audio stream.

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. Would anyone oppose to me posting this same thread on other forums?I will of course post a solution if one is found elsewhere without advertising external websites.
