Record and save audio in c# .net web application

Question

Is there anyway that I can record sound from a microphone using c# .net

• What is the best option if i have to save the audio online in terms of the file occupying storage space.

• Any particular format that the file should be saved in for optimum output.

Answer 1

I think you have to use either a small flash application or a silverlight application to do the actual recording. Then you upload the file to your application using a web service or similar.

And mp3 is sort of a standard file format for sound on the web. So I'd go with that.

Have a look at these projects:

What is the best option if i have to save the audio online in terms of the file occupying storage space.

• May be real media (.rm).

Any particular format that the file should be saved in for optimum output.

• Not sure but I think that depends on your player.
