Audio Management System - Allow User To Add Audio Files Itself Into Database Together With Audio Information
Jan 28, 2010
I'm developing a standslone system for my school project. I'm developing an audio management system which allow user to add audio files itself into database together with the audio information such as artist name and album year. I just started it few days ago and face some problems.. my song in the playlist wont continue to play after 1 finished and i need some idea on how to store the audio files into database ... in blob types may be?
Heres the screenshot and codes
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles bt_add.Click

I just want to ask or I need some idea on how to convert wav files to mp3 and compressed the file to make the size smaller. I've search on the internet and find vorbis.dll as a reference object and lame.exe for converter. With regards to the audio compression, i downloaded monkey's audio software but doesnt have an idea on how to incorporate it.

Im trying to capture the audio played on my laptop. so i have searched the internet and found a source code for doing exactly that. the problem i have is that my audio device is not listed in the dropdown box (see picture) but it does when its run on windows xp (im running windows 7 x64) the goal of this application would be to capture my friends radio stream and save the individual played mp3's to a loction on my hard drive.(yes i have permission) i have included the source code so perhaps some 1 could have a look at it. (source code)[URL]

I 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?

I need to be able to read audio files and manipulate them from within my own program (similar to how Audacity does it). Now, I'm not asking for something with a thousand effects and such, I just need the minimal as far as audio manipulation for .net goes. I really just need to be able to figure out pitches and frequencies being played at what times and the ability to move them all around.

Based on a thread earlier today, and in particular an answer that Cor gave wherein he
pointed to this article, I thought that I'd do some investigation. Many times here the question has come up about playing .mp3 audio files and NOT using the Windows Media Player object. In the article referenced above, he shows how this can be done via DirectX.
I've looked at DirectX before and it seemed ambiguous so I never really dug into it but it turns out to be pretty simple actually! I thought that I'd write this as a step-by-step of what I did so that maybe some of you will find use from it. The whole thing stems around using DirectX and to begin with, you'll need to download and install the SDK for it. If you haven't already,
try this link. Do be aware that it's a large download (about a half gig)! Once that's installed, create a form and add a reference to the class that we need for this. You can do this several ways, but the way I usually do is to right-click on the name in the Solution Explorer, then choose "Add Reference":

Is it possible to capture all/any audio played by a PC into a system.io.stream, so that it can then be run through speech recognition (System.Speech.Recognition.SpeechRecognitionEngine)?Essentially I'm looking to pefrom speech recognition on any audio on the client PC, google seems to suggest that capturing a stream like this can be done using Microsoft.DirectX.DirectSound, however I cannot honestly determine how.

I'm working on a side project which, put simply, allows for the playing of audio files of multiple types through the form or system (My.Computer.Audio.[...]). I need to grab the audio levels of sound currently playing on the system -- not necessarily what's just playing through my form.
A "full-audio graphic visualizer" if you will. However I just need a method of grabbing the data in the first place - the rest I have taken care of. The different values you see in a graphic equalizer are what I need to grab.
If you had music playing via Songbird, and started playing a podcast voice MP3 in Windows Media Player, I want to have it all-inclusive. I've looked in the My.Computer.Audio namespace, looked into Fast Fourier Transforms (which turned out to seem much more adequate for equalizers as opposed to visualizers), and more.

When I referenced speechlib directly there was a method GetAudioOutputs which would return all local audio outputs, which you could later use to select which output to speak to. I don't see that function in System.speech. How can I select which sound card to speak to with System.speech?

Early on the OP was asked "how will you get the data about your music?" and it went into a whole other direction, but that's what I'm here to show: Another way to get the data about your music without dependence on the metadata.The music that I have has fairly extensive tags embedded but as I've discovered, that's not the case with all of them. It's a good starting point I suppose but is there another way? Let me jump to the end, then in the next several posts, we'll dissect the parts of it. My goal was use "only out of the components and methods" and this is what we end up with: Aside from the rudimentary things like song duration, how about if we could get a host of information about the songs, including the cover art? As shown in the example above, some also will have a link to additional information. The additional information may even contain a way to watch a music video for that song like this: Further, some will even contain what I call "Liner Notes" like this:
If this interests you, read on ...This isn't a new thought at all; I've explored this area before. Have a look at this on Code Project. Now before you go thinking that you've found the keys to the kingdom, I should explain a little minor issue about that - it doesn't work! In that, he relies heavily on three web services: Amazon Web Service MusicBrainz LyricWiki Amazon has significantly modified their service such that his methods don't work now. If you follow the posts following the thread, you'll see a few people have tried workarounds but over the years, even those stopped working because apparently they (Amazon) are in a state of flux regarding their API. LyricWiki is still alive and well, but - the music recording industry forced them to no longer offer their service to developers. MusicBrainz is in fact a heck of a resource and if you're at all interested in this topic, I would encourage you to have a look around. It's odd to work with, but it's chock full of good information and they're constantly adding to it or so it seems. All that said, this example won't use any of those but rather a different service all together: Last Dot FM. I can't say that I know much about them, but I happened onto them a few months back when I was first experimenting with all this stuff.

I am working on an application in VB.net (.NET 2.0) where I need to open a dynamic amount of different audio streams. Normally, for audio files, one would suggest importing the Windows Media Player COM reference and adding a GUI-based element from the toolbox, but since I'll be working with a dynamic amount of these a GUI would be a terrible idea (especially with Tab stops).

I have 1-10 audio files that were selected by the user using an "openFileDialog" (with a button and textbox for each). Now, I want it to play all of the files that they selected in a random order when the user clicks "Button12." After all the files have been played, I want it to start over and play all of them in a random order again. I don't want it to stop until the user clicks "Button13." When the user clicks "Button 12" again, it should start playing them in a random order again.

I am developing a server-client voice streaming chat application with vb.net, i am recording wav files by a microphone and using .net.Sockets to transfer the files from a client to the server.
The runtime from the client follows as :
Public Sub sendFile(ByVal file As IO.FileInfo)
Dim BufferSize As Integer = 1024
Dim fs As FileStream = New FileStream(file.FullName, FileMode.Open, FileAccess.Read)
Dim NoOfPackets As Integer = Convert.ToInt32(Math.Ceiling(Convert.ToDouble(fs.Length) / Convert.ToDouble(BufferSize)))
[Code] ......
The problem that I am having is that the wav file that arrives to the server sounds really bad like interrupting each half-second. Another strange thing is that if the originally file es 46KB big the one that receives the server is 47KB. How I will manage to build a voice chat with good quality using this technology. How I can start sending streaming audio meanwhile une user is speaking.

I have a requirement to combine 2 audio files with a video file is this possible with vb.net.What the user basicly wants to do is select 3 files one video, 2 audio, then click a go button and the files be combined to produce a single file, where do I start?
Am wondering if media encoder can do this or do I need to look in other areas?

I have searched and found many articles and code that writes a directory structure to an XML file. However, I'm not having much luck finding/altering code that gives each sub folder a different name. I'm trying to put into XML a folder full of audio files. They are music - artist - album - file. Music is the root folder and file are the audio files but every piece of code calls artist and album the same name. eg

The user can select from either print or audio books and add to the shopping cart. The list box shows all items in the shopping cart. There is a 6%. sales tax on the total cost of the items in the shopping cart and a 2 dollars shipping charge per item in the shopping cart. to remove an item from the shopping cart, the user selects it in the list box and clicks the remove button. the subtotal, tax, shipping, an total fields should be adjusted accordingly.
To add one of the items in the list to the shopping cart, the user selects it and clicks the add book to cart button. to cancel the operation, the user clicks the cancel button. I am using a standard module to declare global variables. My file is attach I have the problem that everytime I add a new item, it will just add 2 and then I add another item and it add 2 it does not show the subtotal or the tax and shipping and the real total....

I need to be able to raise different types of audio notifications to the user. I need an "ok" and an "error" type sounds, I was hoping to be able to raise a simple beep and a critical stop type sound but I can only find the Beep() command which doesn't allow for differing sounds. Is there a library that does what I need or will I need to roll my own using the system wavs.
