The aXPanner by SSA Plugins offers precise control over the spatial positioning of audio, allowing users to adjust the azimuth, elevation, and stereo width of sound sources. It supports both mono and stereo inputs and delivers output in the AmbiX (SN3D/ACN) Ambisonics format, enabling immersive sound placement within a three-dimensional audio environment. Two interface options, equirectangular and top-down, provide intuitive ways to position sounds accurately in space.

This plugin comes in three versions that cater to different levels of spatial resolution. The Free a1Panner encodes first-order Ambisonics, suitable for creating basic spatial sound fields. For enhanced accuracy, the a3Panner encodes third-order Ambisonics, offering improved spatial detail. The a7Panner delivers the highest spatial resolution with seventh-order Ambisonics, providing exceptional precision for immersive audio production within a digital audio workstation.

It is important to note that Ambisonic output requires a dedicated decoder to render the spatial audio correctly, as direct playback of the plugin's output will not produce accurate results. While platforms like YouTube currently support only first-order Ambisonics, industry trends are moving toward higher orders, making the aXPanner’s advanced encoding capabilities a future-proof choice for high-quality immersive audio experiences.
