## hrtf-mode:
# Specifies the rendering mode for HRTF processing. Setting the mode to full
# (default) applies a unique HRIR filter to each source given its relative
# location, providing the clearest directional response at the cost of the
# highest CPU usage. Setting the mode to ambi1, ambi2, or ambi3 will instead
# mix to a first-, second-, or third-order ambisonic buffer respectively, then
# decode that buffer with HRTF filters. Ambi1 has the lowest CPU usage,
# replacing the per-source HRIR filter for a simple 4-channel panning mix, but
# retains full 3D placement at the cost of a more diffuse response. Ambi2 and
# ambi3 increasingly improve the directional clarity, at the cost of more CPU
# usage (still less than "full", given some number of active sources).

## default-hrtf:
# Specifies the default HRTF to use. When multiple HRTFs are available, this
# determines the preferred one to use if none are specifically requested. Note
