I have got following code:

C++

CImage local_image;
			CaptureWndShot(local_main_dialog->web_camera_dialog.m_hWnd,&local_image,ENGINE_WINDOWS_SIZE_CX/2,ENGINE_WINDOWS_SIZE_CY/2);

			IStream *local_stream;

			HRESULT local_create_IStream_result = CreateStreamOnHGlobal ( 0 , TRUE , &local_stream );

			HRESULT local_save_result = local_image.Save(local_stream, Gdiplus::ImageFormatJPEG);

I need to be able to compile following code:

C++

CAudioImage local_audio_image;
			CaptureAudioSampleShot(&local_audio_image);

			IStream *local_stream;

			HRESULT local_create_IStream_result = CreateStreamOnHGlobal ( 0 , TRUE , &local_stream );

			HRESULT local_save_result = local_audio_image.Save(local_stream, Gdiplus::ImageFormatPCM);

And

C++

CAudioImage local_audio_image;
			CaptureAudioSampleShot(&local_audio_image);

			IStream *local_stream;

			HRESULT local_create_IStream_result = CreateStreamOnHGlobal ( 0 , TRUE , &local_stream );

			HRESULT local_save_result = local_audio_image.Save(local_stream, Gdiplus::ImageFormatMP3);

Is it possable?

UPDATE:

I have got for example RAW PCM DATA and AM_MEDIA_TYPE of the RAW PCM DATA.
How can i write the wav file from RAW PCM DATA and AM_MEDIA_TYPE of the RAW PCM DATA?

The CAudioImage class should be able to convert audio formats and should be able to save data to IStream.

What are your real objectives? If just "I need to be able to compile following code:" - well then start writing. There are many audio libraries available (Google will show them) for example OpenAL, FFMpeg. Which ones have you looked at and rejected?

I need the ATL class.

Сергей Козлов 23-Dec-15 22:56pm

Does any ATL class already exist?

I write Skype, TeamViewer, Torrent in one project.

I am not system programmer to write such classes.
The class should be written by system programmers.

The common and complete way to deal with audio streams and conversions is FFmpeg which I mentioned in a comment above. You will need to spend some time with it and I'm sure it will do all you require and plenty more: FFmpeg[^]
Using FFmpeg in Windows Applications | Building Apps for Windows[^]

Found writing wav header in the file "api-band-test.c" from ffmpeg-snapshot.tar.bz2 dating back to 2002 year.
