Call For The Internal Sound Cards And/or Midi Synthesizer?
Jun 22, 2009
I just started programming in vb 2008 Using vb studio 2008 and vb 4.0 Running Windows XP Home Edition My question concerns the capabilities of vb to call for the internal sound cards and/or midi synthesizer.Can a module call the sound card for it to play MULTIPLE notes at the same time, notes of fixed frequency and duration?
I have tried programming vb 4 AND vb2008 for them to modify the default BEEP sound: using a code i found on internet:private declare Function Beep lib "kernel32" (byval soundFrequency as int32, byval soundDuration as int32) as int32

I'm trying to play a MIDI file in my VB.NET (VB 2010 Express) and things work well with the code from this other question here on Stack Overflow, which I translated from C to VB.However, I also need to PAUSE, while that code is only for open and stop. I edited the code like this:
Imports System.Runtime.InteropServices
Imports System.IO
''' <summary>

I have a program that I have been building for quite some time, which is sort of a media center type of program. One of the features it includes is a CallerID and call management system that I have integrated into it.I am actually turning the ringers off on my phones, and the program will have it's own ringer instead. One reason i'm doing that is, it is programmed only to ring if I actually have the number already in my phonebook (i.e. no more telemarketers), and other features like quiet time (after a preset time, let's say 11:00 the phone won't ring).So anyhow I have 2 sound cards in my system. One sound card is connected to my living room home theater, which would be for watching tv, movies, etc.The other sound card is going to a separate amplifier that will power speakers that are throughout the house. I want to be able to programatically tell my program to output sound on the secondary sound card.It will be just a simple wav file, and hopefully speech as well (using the system. speech.speech synthesizer).So no matter if your watching a movie, or playing xbox (meaning the stereo will no longer be playing audio from the computer),when the phone rings you will hear the ringer over the speakers, along with a voice saying "Joe Schmoe is calling".I don't know if I can specifically have it play certain sounds over one card, or if it is a per application setting.For instance, if you are watching a movie (meaning the movie is playing through the windows media player control, inside of my program), and the phone rings, I want the phone to ring on the other card without changing the audio from the movie. If i'm not able to do it that way, and if the program itself is only able to play through one card at a time, I will simply make the caller id portion it's own separate application, that way I could make it happen.

I want to build a system that will take the input from an electric guitar and capture the frequency of the sound. and when the frequency is captured, the system identify the chord, and create new controls to represent the audio frequency. i want to use the label as the controls. so when the controls is created, how can i know that the user is click on what label. is there something like label1.click in vb 2005 express? then when the label is all created, i want the system to read all the labels integer as the sound of midi. so i have to assign what integer for what sound.

I know it is possible to use the internal system speaker to generate sound.
EG
System.Console.Beep(500, 500)
'Beep(FREQUENCY,DURATION)
However i was wondering if anyone knows if it is possible and how to go about using said system speaker to speak - MESSAGE YOU ARE NOT AUTHORISED - for example
I am creating an app that allows admin access via a usb key (this is working fine) and i want their system to sound an alarm with a warning message should they try to force thier way into the admin section without the admin usb key.

I am working on a simple card game. I have done several in the past, but always by creating card images in a picturebox. I would like to call up the cards within the VISTA operating system. I get the following error:Unable to load DLL 'cards.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)
I have made the following declarations:

There is this software called Harping midi. You can view it here [URL] I would very much like to recreate this software but extend on it. For example. I would like to be able to pick up the "midi notes" and then translate that to guitar tabs. I would like it to have the same features (channel filters, tempo control) those sort of things. Where would I start???

I'm ready to start adding sound to a 3D game and I'm looking for a decent Free library.it would not require DX and be something like:
dim MySound as SoundLib.Sound
MySound = SoundLib.LoadSound("soundfile.wav")
SoundLib.Play3DWorld(Location.X, Location.Y, Location.Z, VolumeModifier, MySound)so far all Im finding is expensive, C#, old, or not .NET compatible.

I'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 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.

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.

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.

Is it possible to convert MIDI files (.midi or .mid) into a .wav or .wma file in Visual Basic.NET (2010)? If so:
1: How would this be done?
2: If the output format can be .wma, how can one write the tags (such as artist, album, etc.) to the file in VB.NET?
I am saying .wav or .wma because I know that Microsoft does not have any rights to the MP3 file or something like that.

Hi to all, i really need some help with a piece of code. Im developing an app, which receive midi TIMECODE (MTC) and shows it on a textbox. when i start the app, it runs ok, and shows the mtc on the textbox, but after a few seconds it crashes and shows an error:
"A callback was made on a garbage collected delegate of type 'MidiTesting!MidiTesting.MidiIn_Callback::Invoke'. This may cause application crashes, corruption and data loss. When passing delegates to unmanaged code, they must be kept alive by the managed application until it is guaranteed that they will never be called."
