But have the source of the audio be streamed from over a network(I know how to stream the audio over the network in VB.net) but how do I get that audio which has been streamed as the input to the virtual microphone?

View 6 RepliesAdjust Audio Volume Directly Using .net?
Mar 25, 2012Is there any way to adjust audio volume directly using .net?
I can only find C++ coding which, sadly means nothing to me.
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.
Adjust Master Audio Volume Directly Using .net?
Mar 26, 2012Is 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.

.net Capture System Audio To Stream?

View 1 RepliesConvet My.resources Audio To Stream?
Jan 4, 2011I'm using vb.net and "my.resources" to store wav audio files.I know I can play such files using:
My.Computer.Audio.Play(MyProjectName.My.Resources.Resources.resourcename, AudioPlayMode.BackgroundLoop)
However I want to use bass.net to play the file and it requires either the the file name on the file system or a stream. how do you get the data inside an audio resource into a stream?This is what I have so far:
Dim imgByteArray() As Byte
imgByteArray = CType(MyProjectName.My.Resources.ResourceManager.GetObject("resourcename"), Byte())
stream = New System.IO.MemoryStream(imgByteArray)
[code]....
I get this error on the bold line above:
Unable to cast object of type 'System.IO.UnmanagedMemoryStreamWrapper' to type 'System.Byte[]'.
1. Is there a way to cast from System.IO.UnmanagedMemoryStreamWrapper to type System.Byte?
2. What would be the best method to get the audio resource into a stream format?
Replay A VB Audio File Or Stream?
Sep 21, 2010I am trying to write a little synthesizer program, and as a first step I am creating .wav files opened for reading and writing using the code below called from a button click event handler. The audo plays but once, no matter how many instances of the Audio.Play method are called. I also tried closing the file and then calling the Audio.Play method on the full path name. In each case, the audio plays but once. If I click the button again, the file will be played once more. The duration for the audio is one second, so I am sure that it is only being played once every time. I do not want to loop the data. The idea is that when the user plays a new note, I update the file and replay it with the new data. Since the file is recreated every time I click the button, I guess what I *need* is working, but I am still curious why I cannot replay the content of the file.

Dim FS As New IO.FileStream(fileNamePath, _

Detect Silence Of Audio In Buffer Of WMA Stream?
Aug 24, 2010I have a standard WMA stream, streaming in constantly via the internet. I need to write an application to stream this audio, and looks for any periods of 'silence'. When it detects silence, it runs an event.
For the purposes of this, silence is defined as three seconds of zero-level audio. The stream keeps going in a technical sense, but there is no audible noise coming through it.
However, I want the program to detect the silence while it is still in the 'buffer'. That is, the user won't hear this silence before the program detects it is there.
The audio shouldn't stop as it is analysing this silence - it needs to keep playing the audio constantly to the user.
I'm open to using whatever suitable API is out there - such as BASS, or the Windows Media extensions built into the dot net platform.
Redirect Audio Stream To/from The Serial Port?
Jan 19, 2011I'm writing a program that will allow me to send SMS and call using a GSM modem.
I'm communicate with the modem using AT commands.
I have a problem with "connect" sound from the modem to the speakers.
After installing the modem is visible in the system as two ports.
On one of them sends and receives commands.
The second is just for voice communication.
I can't redirect PC audio input/output to the modem serial port. (So I can't hear callers and vice versa)
From what I've managed to find I have to use SAPI. (ISpVoice::SetOutput)

View 7 RepliesRouting Modem Audio Out To SR Engine Audio Input Under VB / VBA?
May 20, 2009I 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?

May 25, 2012in an winForm app in VS2010 win 7 compiling to x86, I try to do what Alvas.Audio seems to work. See (c# ex: [URL] for reference.
Dim data() As Byte = wr.ReadData(second * i, second)
The result give me data.length()=0. I do not have any exception, I can read format from it and whatever reader I use I got this problem.EDIT : After some tests, it seems like the uncompressed file I create in the first step (in PCM format, with .wav extension) can not be recognized by the Alvas.audio library for the second step. I must miss something around Audio file markups or something alike.
Here is the code that might be the source (basically this is step 1):
Dim functOut As String = String.Empty
Dim wr As Alvas.Audio.IAudioReader = Nothing
Dim fs As IO.FileStream = Nothing
[code]....
How can I write the resulted stream to be sure I can read it again later?
