Free 3d audio software for windows

Realbasic interfaces for FMOD Ex to provide advanced 2D and 3D audio. FMOD Ex Audio Classes will hook into the cross platform FMOD Ex audio library, supporting a wide range of audio formats and playback options, plus physically correct 3D positional audio.
Streams
- Currently these classes do not support disk or network streaming. Be aware that the FMExStream class stores audio data in RAM in its native file format for the lifetime of the object, therefore streams are only practical when using compressed formats, or when stitching is required via the FMExStreamSentence class.
Virtual Channels
- One of FMOD Exs most touted features is automatic channel virtualization. This allows you to play sounds on more channels than are physically available and let FMOD Ex decide which sounds are more important based on priority settings and 3D positioning. One caveat with virtualization is that you must call FMEx.Update as frequently as possible for this to actually work (e.g. in games youd typically call FMEx.Update every frame). NOTE: If youre already calling FMEx.Update for 3D audio you do not need to call it twice.
MIDI
- MIDI playback currently only works on Windows, and only if the default system sound font is installed (/windows/system32/drivers/gm.dls). Broader MIDI support is on the would-like list but primary tests point to a broken implementation on Mac OS X (i.e. some FMOD Ex bugs need to be fixed before this can work).
