Originally developed in the 1970s by Michael Gerzon and a team others,
Ambisonics was created as a means of recording and playing back 3D sound.

Taking advantage of the way sound waves propagate, it is possible to record a
fully 3D soundfield using as few as 4 channels (or even just 3, if you don't
mind dropping down to 2 dimensions like many surround sound systems are). This
representation is called B-Format. It was designed to handle audio independent

In addition, Ambisonics can encode the near-field effect of sounds, effectively
capturing the sound distance. The near-field effect is a subtle low-frequency
boost as a result of wave-front curvature, and properly compensating for this

__ALSOFT_DEFAULT_ERROR
Applications that erroneously call alGetError prior to setting a context as
current may not like that OpenAL Soft returns 0xA004 (AL_INVALID_OPERATION),
indicating that the call could not be executed as there's no context to get the
error value from. This can be set to 0 (AL_NO_ERROR) to let such apps pass the
check despite the problem. Other applications, however, may see AL_NO_ERROR
returned and assume any previous AL calls succeeded when they actually failed,
so this should only be set when necessary.
__ALSOFT_SUSPEND_CONTEXT
Due to the OpenAL spec not being very clear about them, behavior of the
alcSuspendContext and alcProcessContext methods has varied, and because of
