Define the portable spatial contract and user policy independently of speech and cue transports. Declarative presentation rules request normalized stereo balance or listener-relative azimuth; transport compilation reduces that request to the capability of the selected backend.
Non-nil permits spatial presentation of auditory cues.
Default Value:
t
Non-nil enables spatial presentation globally. Disabling this option preserves every speech and cue action but centers it.
Default Value:
t
Maximum absolute stereo balance after user remapping. The value is between 0.0 for centered output and 1.0 for full separation.
Default Value:
1.0
Declared spatial capability of the final audio output. ‘auto’ uses each transport adapter’s reported capability. ‘mono’ forces portable centered compilation even when an adapter can produce stereo.
Default Value:
auto
User remapping applied to normalized balance requests. ‘normal’ preserves direction, ‘reverse’ swaps left and right, ‘collapse-left’ centers positions requested on the left, ‘collapse-right’ centers positions requested on the right, and ‘center’ centers everything. A function value receives and returns a balance in the range -1.0 to 1.0.
Default Value:
normal
Non-nil permits spatial presentation of speech.
Default Value:
t
