Recording Wav From Speakers?
Jun 11, 2009
i recently downloaded a demo game "Delta Force Xtreme 2 BETA". the game it's self, looks like vb3 does when compared to vb.net 2oo8.. one thing about it, on the startup screen, it plays a decent track of music..
i want to record that sound, in wav format, i guess, directly from my speakers. i googled all day, hoping to learn something about playing/recording sound, and i got nowhere.. so i finally decided to post here, after searching the forum for answers, again, without any luck..
i'm not looking for links to sites that the code is not tested before the link is posted.
just a form with 3 buttons. 1 to record, 2 to stop and save, and 3 to play. again, the sound should be recorded directly from the speakers.

I have this problem for some days now and i did not figure it out yet.When i use 2 buttons one for recording and one to stop recording is just fine, but when i use a timer to stop recording does not stop.
Here`s my First i have a button named start recording which calls the Public Sub record and enables timerRecordStop to TRUE.

A simple class that plays a tone of varying ampliture, frequency and duration through the PC's speakers:
Imports System.IO
Imports System.Media
Public Class Form1
Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
Beep.Beep(1000, 1000, 1000)
[Code]...
This class uses SoundPlayer.PlaySync which has a 4 MB stream length limit, so the longest duration is 24000 milliseconds. You can try SoundPlayer.Play for longer durations, but allow plenty of time for it to complete.

Is it possible to play 8 different and individual mono wave files to a 7.1 (8 channels) audio system using vb.net? (I undestand that the .1 speaker is the subwoofer and I'm not yet sure it can be replaced with an ordinary speaker.) The playing should start simultaneously and the files can be of different size/length.Is this something that should be done using win API functions if it can be accomplished at all.I just re-installed my old VB6 which I need to ugrade and vb.net would be the easiest for me so I placed this Q here.

I was just thinking if there is any component which monitors sound output. My intention is to recognize a particular sound coming out from my soundcard. I know its an issue about the driver of my sound card but is there a way I can get atleast noise level coming out of my speakers and maybe draw a graph and detect the peak at when the sound is played?

I am trying to record many small MP3 files from my computer's microphone. There are numberous examples using mciSendString Library "Winmm.dll" to record .wav files. I find the .wav quality to be lacking and I really want to record straight into the MP3 format rather than converting my .wav files.

Am new to the VB platform and have only been messing around with 2008 for a few months,off and on.Have built a rotational inertia based Dynamometer for personal use in my R/C hobby.Have written some code that allows me to read roller frequency,that is then figured to roller RPM,and eventually ,vehicle ground speed.
Now before anyone shoots me down,( I don't mean this to be sarcastic,but I have received negativity on other forums) I know that ,because of various interupts on my P.C.,that the windows timers aren't all that accurate,causing me to miss incoming signals that screw up my measurements, and the best thing is an external aquisition unit.Let me just say that I run my VB program parallel to an external frequency counter,and have at any given time a difference of max. 8 hz at higher revs.Also I use an external timer based counter that figures the ground speed ,and it also is within a half KmH.This is only a hobby for me and that's close enough.Someday I may build something that does the computing externally and gives it to VB,but for now.........So now to the good part
Here's my question: How can I write code that will let me record the RPM ,from TextBox2, at each timer interval,and have them listed?
I need this to calculate the RPM changes per interval in order to establish "angular acceleration" ,for further calculations.
In Addition,I need a way for my program to know when something changes or does'nt.If I start my programm and don't run the dyno ( no signals) then it will start saving a bunch of zero's that I don't need,and when I get to the end of the run,the RPM will top off(no change in signals)but keep saving.The best would be,start recording when the 1st signal is detected and stop recording when the signals stop changing, and tell me I can stop.
But I'm not that advanced.........yet.
The next problem is that I have no idea,depending on what vehicle I test, how many intervals will be recorded, as one may or may not take longer to reach max.RPM.
Heres what I have so far:
Public Class Form1
Dim product1 As Double
Dim product2 As Double

My project uses an MS Access Database, and amongst other things records the current cost of a series of categories which are regularly updated, thereby erasing the previous entry. However, I need to retain all previous costs to produce a history graph for given periods. I have considered importing an Excel spreadsheet, but having a functioning database it seems sensible to use it.

I achieve to record and stop recording (manually with a button).
Now i want somehow to automatically stop recording after some seconds.
I used the following methods which did not work:
1. Used a timer to call the stoprecording function (I found out that while recording the timer did not work) I tested it with an msgbox and i was right, the msg box appeared 5 secs after pressing the stoprecording button!!!!
2. Used the System.Timers.Timer but nothing
3. I tried the CAPTUREPARMS structure but i`m doing something wrong and it doesn`t record.
Here`s my initialization:
Dim MyParams As New CAPTUREPARMS
With MyParams
.dwRequestMicroSecPerFrame = 66667

I Would like to make an appliaction in c# (or vb.net) that records every sound that comes out from the speakers when i tell it to, and when im finished i want to push a button and save it as an mp3 (or some other format).
So far i have only found APIs that can record something from a microphone.
Is there anything in the .NET framework or is there some API for making this possible?

I have a database in MSSQL that I'm using in a VB.NET project. Three of the fields are dates, so I leave the default DateTimePicker as the means of entry. The problem is, when I make a new record, the date from the DateTimePicker only makes it to the database if I select a date. If I leave it as the default(today), then the information does not record, leaving a NULL in the database.

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 want to select either "Wave" or "What U Hear" or "Microphone" or "Analog Mix" (LineIn) in the Windows Recording Control applet, i.e. as if I clicked the applicable "Select" checkbox.
I got this VB6 code on the Net (not sure where) and tried to convert it to VB2008. It is very near to correct I think, but the last part does not work.

I need a simple program that makes sure that the LINE IN is the selected input for recording. I can handle the program itself, I just can't find how to check the selected input at any given time. Note that I shouldn't interfere with any running program.

I am trying to make a program that can send voice over LAN. I already have the connection between the computers working, but I can't really seem to find a way to actually record + stream sound.
I've found out that I can use
Private Declare Function mciSendString Lib "winmm.dll" Alias "mciSendStringA" (ByVal lpstrCommand As String, ByVal lpstrReturnString As String, ByVal uReturnLength As Integer, ByVal hwndCallback As Integer) As Integer
and then
mciSendString("open new Type waveaudio Alias recsound", "", 0, 0)
mciSendString("record recsound", "", 0, 0)
mciSendString("save recsound *PATH*", "", 0, 0)
to save and record sound.
But I haven't really been able to find any documentation on that function, so I haven't been able to find out for myself, how I can send the recorded sound over LAN, instead of saving it on the computer.
