Audio recording in C# ... how?

[Meng Zhuo]

Hi

I would like to record audio from my mixer source (microphone,
line-in, midi...) to wave (PCM) format (filename is known) ... that's
all. I've been looking for a really long time now on the internet, The
Code Project, forums ... everywhere, the only thing I can find is how
to play audio files and some XML stuff. It's the first time I have to
create a C# audio program, so ... ;)

Thanks to anyone who can tell me how to do this

You need to use DirectX, specifically DirectShow I believe. It's quite
complicated to get DirectShow up and running in C# but once you do it would
be fairly easy to achieve what you want. First, download and install the
DirectX 9 SDK and then have a look at these samples:

https://sourceforge.net/projects/directshownet/

Also have a look at the samples in the DirectX SDK as well as the help file
provided with it. There is a direct show book provided by microsoft that is
excellent which I got second hand off amazon for $12.

Meng,

You obviously didn't check out the Code Project well enough. Here is a
link to an article with code:

There are other coding examples for recording found at the Code
Project. In fact, I used code from this source to create an application
that lets me record from sound cards.

By the way, you don't need DirectShow. Either DirectSound or the
WaveIn/WaveOut APIs will suffice.
