'Listen' To Microphone Input And Playback Simultaneously?
Mar 23, 2012
I'm developing a Public Announcement appplication with two main features:
1. Record audio and playback on event (I've achieved this)
2. Allow 'realtime' playback on event - no recording, just a live announcement
So, how can I cause the microphone input to be sent to the speakers simulatiously as the announcer speaks?
mciSendString("open new Type waveaudio Alias recsound", "", 0, 0)
mciSendString("play recsound", "", 0, 0)

I need to make an application that plays the microphone line in the same time I speak to it, somewhat like an amplifier, so I can talk to the microphone without recording and my speakers play that sound at the same time! Its pretty difficult for me because I am really new at this type of applications and off course I don't have any idea about microphone line in volume control coding too!

I'm writing a windows application that need to access the raw data of the microphone input. Basically there's an electronic circuit connect to the microphone jack, and I need to get that data and process it. All I could find are some examples of using API to save the data to a wav file or something like that. But I need to process the data in real time. Get the exactly value of the input on that time. Is it possible?

Is a way of creating a program (either in C(+,++,#) or VB.net) that would be able to send a beep sound through the same line-in that is being used for audacity (not stereo mix)?
I am trying to make a way of syncing up audio and video from 2 different programs, in a similar way that a clapper bored works in the movies.
Would there be a way of using a sort of microphone enhancement that could be created because they affect the microphone input?

I want to make an app which on loading sits in the system tray and even after I open another program (say notepad or vlc or anything) i.e. even when the app is not in focus and if I press "G" on my keyboard, the tray icon should show a tool tip - "key G is pressed". I have tried several codes but nothing works when the app goes out of focus. I can use Register Hot Key [url] but it needs a modifier also (like Ctrl or Alt etc. along with my key G). So, is there any way I can achieve this? something which many tray icons do like antivirus apps, etc. and I do not want to use AutoHotkey application.

How can you access the webcam and microphone in VB.net, assuming the user even has one?
I fail to see a My.Computer.Webcam or My.Computer.Microphone, both of which would probably have been a nice addition.

I would like to add a virtual microphone (similar to how you can have a virual CD drive and then mount ISO files on it.) so that it can be selectable in programs like MSN and skype. 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?

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 am working on mouse recorder and I got it where it will record and playback the mouse movement by using 2 simple listbox and some codes. But now I am stuck on how to get it to record the clicks and also playback that as well. I was wondering if I could just use another list box to store the clicks in it? But I am sure I got to do something more extreme.

I am writing a program to record and playback all the keyboard and mouse events using the journalrecord and journalplayback methods. The code also stores this recorded event in the file and opens the file for playing. The mouse movements are playing fine but none of the mouse clicks or keyboard keypresses are playing fine. Attaching the record and playback hook procedure.

What I need is an application that can have several audio files open up, which in turn can be routed to any of the audio output devices (e.g. external audio card channels). See the attached image for an illustration.

Basically my program has a "shuffle" music feature:
vb For i = 0 To 26 num = randomObject.Next(0, 27) My.Computer.Audio.Play("C:UsersMcturtlesMusicSongs" & num & ".wav", AudioPlayMode.BackgroundLoop) Next
Which selects a random number 0 - 26 and selects the corresponding song.
And a straight play feature:
vb Dim counter As Integer Do Until counter > 26 My.Computer.Audio.Play("C:usersmcturtlesmusicsongs" & counter & ".wav", AudioPlayMode.WaitToComplete) counter += 1 Loop
All of these activated by a button(separate for each)
When I click one, it makes the program stop responding. I'm pretty sure it is the .WaitToComplete mode, but I can't find a way to make it continuously play without it. If you can find my error. Also if you could tell me a way to make the shuffle never play the same song twice, that would be awesome as well.

I have the code working with entering in ips, however, when i use the IPAddress.any command it will not send messages.

This is my first post, so hopefully I'm asking it in the correct place.
Currently I have two subs where the first calls the second.
Sub Sub1()
'some code
Call Sub2(x)
End Sub
Sub Sub2()
'some code
End Sub
This means that Sub1 does not end until after Sub2 is complete.I need to have Sub2 run after Sub1 has ended. In my case Sub1 is triggered from an application event, so calling the two subs from another 'parent' sub would not work.Is there a way that I can listen for the 'End Sub Event' of a sub?I am currently working in VBA but will be heading to .net shortly so I'll take whatever flavour of code people can help with.
