I'm contemplating adding a voice recording to some posts on my site. I'm wondering if there is an ASP.NET library out there that will allow me to:
Press a button to start recording
Record what I'm saying through my comp's built in microphone
Save the file as a .wav or some other popular sound file
As of now, I will be the sole user of this function, but it would still be nice to have in my bag of tricks in case I want to pull it out later for a client.
It is not doable without the help of a plugin. Browsers simply don't support voice recording.
You could choose from:
Make a SilverLight applet.
The flashPlayer can record too.
find a java Applet that can do this.
Make an activeX Plugin (since you have affinity to asp)
use your os provided voice recorder, save the file and upload it. Playback via browser is easy
You solution will involve a flash componet (outside of rendering the markup that invokes the flash component). The ASP.NET stack won't be able to do it. Silverlight doesn't seem able to do it.
Here is how.
Here's the problem: the browser does not allow this level of hardware access by an application. You could however achieve this either through Java, Flash or ActiveX (Yuk! don't do it) should the end user allow the access to occur however there are a number of cavaets. Here's a great thread where like-minded people like yourself are approaching the same challenge:
http://drupal.org/node/69242
If I were cornered to do this I would create a signed Java Applet.
not directly from asp.net since asp.net is server side and you need access to the client side microphone - however the new adobe flash player has the ability to access the mircophone so in theory you could use flash to record then upload to your site.
See ListenUp sdk. I found a bulletin board called english-test.net that is using the sdk to post voices.
You'll need some client-side code to achieve this as regular HTML doesn't support audio input and upload.
The ActiveX control Active Audio Record 2.0 claims to support recording audio and uploading it to an ASP.NET web server. I've never tried it though.

I want to place a button in my ASP.NET Web Forms projec, that connects directly to my Scanner (hardware). Scan & Upload.
Is there a way to do so?
(Activex, etc.)
Thank you
Did you try TwainX, it says.
"Easily integrate Scanners into your web-based applications with a minimum of ... of indirection"
http://twainx.sourceforge.net/
If this is an internal scanner accesible to your company, there is sense in doing this, but if the general public has to do it, they will have to install the activex and all, not recommending your approach. Might as well ask the user to scan it, and then upload the image.
This article - Scan and Upload Documents in ASP.NET MVC App using Dynamic Web TWAIN - may help you as an alternative
I found this post that includes source code that uses the ASP.NET to show how to scan on the client side and then upload the images onto the server:

I've done a good bit of research to find an upload component for .NET that I can use to upload large files, has a progress bar, and can resume the upload of large files. I've come across some components like AjaxUploader, SlickUpload, and PowUpload, to name a few. Each of these options cost money and only PowUpload does the resumable upload, but it does it with a java applet. I'm willing to pay for a component that does those things well, but if I could write it myself that would be best.
I have two questions:
Is it possible to resume a file upload on the client without using flash/java/Silverlight?
Does anyone have some code or a link to an article that explains how to write a .NET HTTPHandler that will allow streaming upload and an ajax progress bar?
Thank you,
Austin
[Edit]
I realized I do need to be able to do resumable file uploads for my project, any suggestions for components that can do that?
1) Is it possible to resume a file upload on the client without using flash/java/Silverlight?
No. The actual HTTP protocol itself does not support resume of partial uploads, so even if you did use flash or silverlight, you'd still need to use something else like FTP on the server.
I've "solved" this problem in the past by writing a custom client application in C# which broke the file down into small chunks (2meg), transmitted those separately, and then the server combines them all back together.
2) Does anyone have some code or a link to an article that explains how to write a .NET HTTPHandler that will allow streaming upload and an ajax progress bar?
While this doesn't solve the 'resume' problem, I've used SWFUpload on the client side and it worked brilliantly. It provides a smart file browser (where you can prompt the user for only jpeg files, etc) and upload progress tracking, all without needing to modify your server at all.
It's not possible to resume an upload using standard HTML file input control, because the whole file gets submitted with the HTTP request.
I've used NeatUpload in the past, which gives you a progress bar. It's under an LGPL license, so you don't need to pay for it and it's open source.
Nothing more to add about the resume problem.
I used (and keep on using) telerik radUpload and I am quite satisfied with it
(it can even be used in medium trust mode which was quite important for me). The only problem I had (and was not able to fix) is to upload files bigger than 2GB...
SlickUpload is pretty solid and a lot of big companies use it from what the site says.
This is probably too late for your project, but POW Upload have now implemented auto resume upload in their new version. We're about to implement it on our site.
work on asp.net 08 C#.I would like to develop a web application that scan documents into the following format(pdf,tiff,jpg,gif.etc) .My scanned images/file will be at client computer.
Have you tried using an 3rd party scanning control such as LeadTools? I have used those controls in the past and worked wonderfully.
Brining in a scanned document through the browser goes beyond the basic functionality of the browser.
If you must stick with ASP.NET, you might consider writing an ActiveX control (IE only, I think) that can handle the scanning and interact with your web page.
You might also consider Silverlight. Although I don't think it can handle the scanning directly, you should be able to interface with COM components installed on the system to handle scanned streams.
The wording is sort of ambiguous. Is the scanner on your side or the client's side? I understand that the result of the scan is saved on your client's side.
I assume that the scanner is on the client's side...
You can't access peripherals [ie: a scanner] via standard JavaScript... You can take advantage of ActiveX for IE only.
Why not write a small winforms application in c# and let your client download that?
By the way, if the client has a scanner on his/her side, the scanner will likely have come with software to manipulate the scanner...
I am wondering if there is any codes sample for ASP.NET with Voice recording.
Ok, Basically, i want to create a web page that allow user to click a record button and record his voice thru his/her microphone and then convert it into mp3 file, then i want to click PLAY button to play what was recorded.
I have searched google alot and cannot find any codes that code do just that.
I have seen site that can do just that and it is using FLASH with RoR (i think).
Is there any way to record voice using ASP.NET?
I dont care if it need to combine with FLASH with ASP.NET, as long as it is possible.
Thanks.
EDIT:
Stephen M. Redd,
Appreciate your input. Yes, i know there is no simple way to accomplish what i am asking for. I also have researched and google alot on this question. Yes,I have come to know the best way to do this is through using FLASH with either FMS or RED5 (open source).
So i am trying to figure out how to write a simple FLASH (.swf) that i can record voice and then save into mp3 format to RED5 server.
Do you know or can you provide any directions to what i am asking above?
1) Tutorial on Microphone class in FLASH (i am reading some basic implementation from a book called "FLASH Actionscript in a classroom", which doesnt tell me how to record voice but ONLY how to use microphone object in FLASH)
2) Tutorial on how to setup and use RED5 (FMS is NOT an option due to its cost)
3) how to integrate 1) and 2) with asp.net and javascript (if there is any flashvars that the FLASH microphon .swf i can access so that ASP.NET can be used with javascript)
Thanks.
EDIT 2:
I cant consider to accept an answer BECAUSE none of them has provided a good answer.
Take a look on my question and read the comments i got, and you will see that my question was NOT being provided a good answer.
My question is to find a web-based Audio/Voice recorder so that the users can record their voice on the site.
To better convey what i exactly asked for, take a look at www.snapvine.com or www.pubclip.com . Both of them provide a way for users to record their voice right on the webpage.
So, i am looking for a FLASH component (.swf) similar to what they offer to integrate with my site.
EDIT 3:
This voice/microphone recording thing seem to be a challenging project for most developers.
I guess this means i am all alone.
I think this is something that would have to be done with Flash.
This guy appears to have some examples of doing voice recording in Flash, with code samples:

There is no simple way to do this kind of thing. Standard web technologies based on HTTP and HTML just don't have the features. HTTP doesn't work well with moving audio data, and HTML and Javascript are not able to talk directly to the hosting OS or hardware resources like the microphone.
There are 3rd party browser plug-ins and applets that you may be able to use via a web application to do this kind of thing.
Most people use Flash and the Flash Media Server to do audio input via the web.
There are also some Java applets that have similar capabilities such as the ListenUp SDK (I have not used this, so it isn't an endorsement).
There is a lot of discussion on this topic related to Microsoft Silverlight, but as I understand it voice and camera inputs from the client side are not supported as of Silverlight 2, though it may get put into Silverlight 3. There is a good bit of information about how to use the necessary Flash bits within a Silverlight application though. For more info on that, check out this post.
ASP.net is a Server-Side Technology, but voice recording is done Client side. So regardless if you use ASP.net, PHP, Ruby on Rails or Cobol, you can't do it directly.
What you need is a Client-Side Application that works together with the Server Side to accomplish this. I do not know if Silverlight can do Microphone recording, but Flash can. This is apparently quite easy using the Flash Media Interactive Server, but normally you should be able to do this without, i.e. just by having a Flash Application doing the recording and then Uploading it to the server.
Hi Sam in Silverlight 4 it is possible to record voice from microphone and webcams.
Just follow the blog.

Good Luck
I am working on an ASP.Net application and I want users to be able to take a picture with their local webcam and then upload it to the server.
I can, of course, rely on users doing this manually via their locally installed software, save the image as a file and do a normal file upload. However, what I really want to do is incorporate it all into a UI in the browser.
I know this means accessing local resources so do I need an ActiveX control or Silverlight or is there something I could do in Javascript for example?
This is initially intended for an Intranet app so I can have control of the client's environemnt, including stipulating the browser etc, which means I can use an ActiveX control if I have to. However, it would be nice if I could write this in a generic way so it could be used in an internet app generally (happy to stipulate that it only works on Windows clients but would be good to get it to work in FireFox).
Thanks.
The only acceptable and universal way to this for now is Flash/Flex application. Flash player presets literally in every browser in the world and all of them has such capability.
VideoCap Pro is quite popular, and it offers an ActiveX version, have you checked it out?
This sounds very suspicious to me. You realize the nefarious applications this could be applied to, right? A web page that when a user browses to it, unknownst to them, their webcam snaps a pic of them. ... I don't like it.
You could use the Nimbb API to do the webcam video recording inside a browser.
It is possible to get the image from client webcam in asp.net, you have to install the Silverlight 4 with Visual Studio 2010:
