What's In A Wave File

Jun 17, 2009

I am trying to convert a mp3 to wav and I need to know...What is the very first thing you see when you open a wave file up? the 2nd, the 3rd, 4th and so on. Is it the riff header or the riff header contents(ID, size, Type). I need this info for a Regex string that would look something like this...

'Frame/MaxFrame (PercentDone%) | CPU time/estim | REAL time/estim | play/CPU | ETA
Private Shared _regLine As Regex = New Regex( _
"(d+)/(d+)D+(d+)D+([d:]+)D+([d:]+)D+([d:]+)D+([d:]+)D+([d.]+)D+([d:]+)"

[code]....

I am executing lame.exe from a process.Start command.VB 6.0, VBExprss, ASP,Net, & Gaming

Wave File Won't Play?

Oct 4, 2008

So, I re did my project in VB.NEt instead of C#. So, I put all the sound files in the resource files. I made a routine to play the sound file but it says that to make sure the sound file exists. Which it does because it played in the resource manager.Here's the sub routine to play the sound:

Dim sndplayer As New Media.SoundPlayer
Public Sub TestSound(ByVal snd As String)
My.Computer.Audio.Play(snd)

VS 2008 MciSendString Save Wave File

Jul 19, 2009

I have a created a small application that records and plays audio. However, my application needs to save the wave file to the application data directory on the users computer.The mciSendString takes a C style string as a parameter and has to be in 8.3 format. However, my problem is I can't get it to save. And what is strange is sometime it does and sometimes it doesn't. However, most of the time it failes. However, if I save directly to the C drive it works first time everything. I have used 3 different methods that I have coded below. The error number that I get when it fails is 286."The file was not saved. Make sure your system has sufficient disk space or has an intact network connection".[code]

Sine Wave Using Timer Component?

Feb 28, 2011

[URL]..I wrote a program with a timer set to tick every 100 ms. The values oscillate between 109 and 110 ms. Each tick, a variable adds +1 to itself; it starts at 0 and goes to 9 and then it goes back to 0 where it continues the addition process. When the timer ticks 110, the variables is added to a textbox. The pattern is something like this, which you can see in the above youtube video. 5 9 5 9 5 9 4 8 4 8 4 8 3 7 3 7 3 7 etc.

Game Programming :: Playing Wave Files In An Application

Nov 20, 2008

I have a program that speaks wave files. This works problemless with the Soundplayer class with the following code:

Sub MyPlayWav(ByVal WavFileName As String, ByVal StartPos As Long, ByVal EndPos As Long)
Dim wp as new SoundPlayer
wp.SoundLocation = WavFileName
wp.Play
End sub

The soundplayer does however not seem to have a method to play the wave from position StartPos to position EndPos and achieving just that would mean quite a reduction in downloads of these files.

The soundplayer does have a stream object, and that does have a seek method, suggesting that there might be a way to accomplish this, but how?

I plan to include other media files as I am developping the project, and I guess I will be confronted with the same problem.

Build An Oscilloscope And Display The Signal As On And Off (square Wave) From The Encode?

Feb 26, 2010

I am trying to build an oscilloscope; I will be using a signal coming from digital encoder going through MAX232 logic level converter to the PC via the serial port 1. The signal from the encoder is 3VDC when it is high and 0VDC when it is low, the encoder resolution is 1024 PPR, the encoder is attached to motor (1800 RPM) so the max resolution is 1843200 pulses per minute or 30720 pulses per second. I would like to make my form display the changing of the input from the serialport1 to graphical display just like the digital oscilloscope. I

I want to be able to display the signal as on and off (square wave) from the encoder and be able to display the signal as speed so when the motor is running at full speed the line be at the top of the graph and when the motor drop to 20% of its full speed the line will drop to 20% and so on.
