VS 2008 Recording Audio - Capture The Audio Played On My Laptop
Jun 11, 2009
Im trying to capture the audio played on my laptop. so i have searched the internet and found a source code for doing exactly that. the problem i have is that my audio device is not listed in the dropdown box (see picture) but it does when its run on windows xp (im running windows 7 x64) the goal of this application would be to capture my friends radio stream and save the individual played mp3's to a loction on my hard drive.(yes i have permission) i have included the source code so perhaps some 1 could have a look at it. (source code)[URL]

I have been all over this site looking at and trying example code, but none of it seems to work properly on my computer. I just want a simple program in VB.NET 2010 that can record a .wav file from my computer / line-in microphone. I am somewhat familiar with VB, but I still consider myself a novice and I don't really know all of the audio jargin. [URL]..

I have written a console app in <acronym title="Visual Basic">vb</acronym> .net 2003 to capture audio data (albeit not for an audio application) using the WinMM API. This works well in XP and also on my own Vista PC. However when others try to use in on Vista or Win7 it stops working after about 10 - 30 seconds (so it manages to initiate recording from the default input device but eventually stops). The only error given is "Program has stopped working". I am wondering if this is related to the way I recycle the input buffers?

I just want to ask or I need some idea on how to convert wav files to mp3 and compressed the file to make the size smaller. I've search on the internet and find vorbis.dll as a reference object and lame.exe for converter. With regards to the audio compression, i downloaded monkey's audio software but doesnt have an idea on how to incorporate it.

I 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?

Is it possible to capture all/any audio played by a PC into a system.io.stream, so that it can then be run through speech recognition (System.Speech.Recognition.SpeechRecognitionEngine)?Essentially I'm looking to pefrom speech recognition on any audio on the client PC, google seems to suggest that capturing a stream like this can be done using Microsoft.DirectX.DirectSound, however I cannot honestly determine how.

I am planning to create a proprietary Windows application that will let the user capture video and audio from any other Windows application and stream it onto another computer via Internet. Capturing video is easy, I could simply let the user browse all open windows (or applications) and have the user click the prefered one. But what about audio? Is it possible in Windows to capture the audio from any application?

We have an occasional board meeting that is broadcast live via the Internet. We are on a 3000+PC LAN and our office is out in the boonies on a T1 line. In order for us to listen to the meeting we need to go to a website and play the live stream. If more than a few PCs listen in the line is saturated and no one can listen.

I know it is possible to have more than one audio output device attached to a computer. For example, my home machine has a soundblaster card as well as stereo speakers attached via a USB M-Audio controller. I know that windows and other applications can select which output device to use... I use the sound card for normal Windows sound, but I use my M-Audio output when mixing music in Cubase.The question is, from inside my own program, I need to be able to detect what audio devices are available, show the user the list and let him choose one, and then use that output device for all audio output generated by the program.
It would also help if I could determine which audio output device is being used by Windows.
Oh, almost forgot, I am using Microsoft.DirectX.AudioVideoPlayback.Audio to play mp3 files.

I am currently trying to find a way to play an audio stream from the internet so I thought that someone here might be able to help me. The stream I want to play is specified in a .m3u file and it is not a live stream, it is pre-recorded. This component is for a WPF Browser Application I'm developing.I thought of using the ActiveX MediaPlayer from WMP.dll but it's lack of intuitiveness confounded me. I would really dislike having to download the whole audio track before playing it since the file may be really large and take a long time to complete. Playing the file in Windows Media Player as an outside player is also out of the question.

I have searched and found many articles and code that writes a directory structure to an XML file. However, I'm not having much luck finding/altering code that gives each sub folder a different name. I'm trying to put into XML a folder full of audio files. They are music - artist - album - file. Music is the root folder and file are the audio files but every piece of code calls artist and album the same name. eg

So I'm a bit new to the whole Vista/7 audio setup. My understanding is that a new "mixer" is created for each application. Is there some new .Net function which interfaces with these mixers? I'm actually trying to create an application which can adjust the MAIN system volume level as well as the mute function.
I was looking at the Endpointvolume API however I cant get it to work for me :(. Does anyone have a vb.net demo of how to harness this API?

I have my forms all set up, I want a button on my main form that says Volume. When clicked it either opens a window above the current form with a volume control. Or opens another form that has the volume control in the center. When the slider is moved up to 100% windows is at 100% volume, when moved down windows volume moves down also.

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.

how to play video or audio in a vb.net application but have come up with not a lot.
I want to create a program that accessing a web server (no problem on that) and will pick up audio and video that is stored on that server.
Or, maybe do a live broadcast where I can play my guitar and sing a song. (Promise if I get this done through here I will give you a live performance) on that note I am sure you will all hold back.
This is a little open and wide, but what I would like to know via a webserver is this possible
1.Video
2.Audio
3.Live broadcast
