We should use OpenAL for the sound that way we will have all these features without a lot of work. www.openal.org ----------------------------- What is the OpenAL Audio System? OpenAL (for "Open Audio Library") is a software interface to audio hardware. The interface consists of a number of functions that allow a programmer to specify the objects and operations in producing high-quality audio output, specifically multichannel output of 3D arrangements of sound sources around a listener. The OpenAL API is designed to be cross-platform and easy to use. It resembles the OpenGL API in coding style and conventions. OpenAL uses a syntax resembling that of OpenGL where applicable. OpenAL is foremost a means to generate audio in a simulated three-dimensional space. Consequently, legacy audio concepts such as panning and left/right channels are not directly supported. OpenAL does include extensions compatible with the IA-SIG 3D Level 1 and Level 2 rendering guidelines to handle sound-source directivity and distance-related attenuation and Doppler effects, as well as environmental effects such as reflection, obstruction, transmission, reverberation. Like OpenGL, the OpenAL core API has no notion of an explicit rendering context, and operates on an implied current OpenAL Context. Unlike the OpenGL specification the OpenAL specification includes both the core API (the actual OpenAL API) and the operating system bindings of the ALC API (the "Audio Library Context"). Unlike OpenGL's GLX, WGL and other OS-specific bindings, the ALC API is portable across platforms as well. ----------------------------- Best Regards, Oliver C. _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
