1. Software implementation of OpenAL using openal-soft instead of hardware implementation. This fixed the bugs of OpenAL hardware implementation

2. 3D sound volume (See Insert > 3D Sound)

3. Global sound volume (See Modify > Current VScene Properties dialog)

3. New scripting APIs:

//the following APIs are valid for both ambient and 3D sounds. Note that ambient sound files are stereo (2 channels) and 3D sound files are mono (1 channel)

– SetSoundVolume(string soundName, float volume)
– SetSoundPitch(string soundName, float pitch)
– SetSoundPlay(string soundName, bool play)
– SetSoundLoop(string soundName, bool loop)

– GetSoundVolume(string soundName)
– GetSoundPitch(string soundName)
– GetSoundPlay(string soundName)
– GetSoundLoop(string soundName)

//the following APIs are only valid for 3D sounds

– SetSoundPosition(string soundName, float x, float y, float z)
– SetSoundRollOff(string soundName, float rollOff)
– SetSoundReferenceDistance(string soundName, float distance)
– SetSoundMaxDistance(string soundName, float maxDistance)

– GetSoundPosition(string soundName)
– GetSoundRollOff(string soundName)
– GetSoundReferenceDistance(string soundName)
– GetSoundMaxDistance(string soundName)

//APIs to set and get global sound volume at runtime
– SetGlobalSoundVolume(float volume)
– GetGlobalSoundVolume()
