The windowed sinc filter generation code seems to be working fine. The FIR filtering code is also now working reasonably well. Occasionally the FIR filter will pop, but setting the normalization factor lower seems to help this. I suspect the problem is in the fixed point multiply/add. I also have a hunch the zero stuffing/sample discarding code is not correct, and I'll look at that soon to get it sorted out.

Project files for embedded Visual C++ 3.0, 4.0 and Visual Studio 2005 can be found in VisualCE.zip SDL supports GAPI and WinDib output for Windows CE. GAPI driver supports: - all possible WinCE devices (Pocket PC, Smartphones, HPC) with different orientations of video memory and resolutions. - 4, 8 and 16 bpp devices - special handling of 8bpp on 8bpp devices - VGA mode, you can even switch between VGA and GAPI in runtime (between 240x320 and 480x640 for example). On VGA devices you can use either GAPI or VGA. - Landscape mode and automatic rotation of buttons and stylus coordinates. To enable landscape mode make width of video screen bigger than height. For example: SDL_SetVideoMode(320,240,16,SDL_FULLSCREEN) - WM2005 - SDL_ListModes NOTE: There are several SDL features not available in the WinCE port of SDL. - DirectX is not yet available - Semaphores are not available - Joystick support is not available - CD-ROM control is not available In addition, there are several features that run in "degraded" mode: Preprocessor Symbol Effect =================== ================================= SDL_systimer.c: USE_GETTICKCOUNT Less accurate values for SDL time functions USE_SETTIMER Use only a single marginally accurate timer SDL_syswm.c: DISABLE_ICON_SUPPORT Can't set the runtime window icon SDL_sysmouse.c: USE_STATIC_CURSOR Only the arrow cursor is available SDL_sysevents.c: NO_GETKEYBOARDSTATE Can't get modifier state on keyboard focus SDL_dibevents.c: NO_GETKEYBOARDSTATE Very limited keycode translation SDL_dibvideo.c: NO_GETDIBITS Can't distinguish between 15 bpp and 16 bpp NO_CHANGEDISPLAYSETTINGS No fullscreen support NO_GAMMA_SUPPORT Gamma correction not available
