Dear OpenAL developers,
as someone who is interested in virtual acoustics I started reading the
openal-soft source code. While doing so, I thought it might be
interesting to write a more sophisticated panning algorithm. The current
implementation is great in terms of computational complexity, but a
little bit simple. My new implementation is energy-preserving and should
result in smoother movements of sound sources. It takes the positions of
the speakers for different speaker setups into account and uses a
look-up-table to reduce the computational complexity. As this
look-up-table contains pre-calculated panning values, other panning
algorithms could be implemented at no additional runtime costs, too
(e.g., Gerzon's 3-channel panning algorithm). If you are interested in
the code, you can find my patch against openal-soft version 1.5.304 on
our web server:
