Record audio (WAV) in VS2005...

[hzgt9b]

Using VS2005, VB.NET,
I want to record audio from my sound card, or mic input... and while
recording get feedback to create a sound meter for visual display. Due
to budget constraints, I can't purchase any 3rd party APIs and most of
the free ones I've found are written is C or C++ (not my
proficciency).

I have seen articles on using the "Waveform Audio Interface" but it
doesn't seem to provide the ability to get feedback about the recorded
audio.

Can anyone suggest any APIs or points or better yet examples of code
that can perform such a task.

Any input appreciated.

My company is using DirectX to do that, but I can't give you any code
(confidential).
Hope that helps.

Do you have any examples you can point me to?

What version of DirectX did you develop this under? What interface
provides the feedback on audio levels that can be plugged into a meter
control?

A quick Google search turned up a few links. At least the
first is relevant to your quest. In .Net land, however, it is
easier to find samples written in C# than VB.Net, so
you will just have to do the necessary conversions - or
stick to C#:
