The DAFx audio technology conference took place this year in the idyllic seaside resort Aveiro in Portugal. Dylan Menzies presented a paper Surround Sound without Rear Loudspeakers: Multichannel Compensated Amplitude Panning and Ambisonics. This extends previous work on compensated panning to 3 or more loudspeakers, using an efficient formulation. The comparison is made with Ambisonic reproduction using the same loudspeaker layout.
