In addition, Ambisonics can encode the near-field effect of sounds, effectively capturing the sound distance. The near-field effect is a subtle low-frequency boost as a result of wave-front curvature, and properly compensating for this -occuring with the output speakers (as well as emulating it with a synthesized +occurring with the output speakers (as well as emulating it with a synthesized soundfield) can create an improved sense of distance for sounds that move near or far. diff --git a/docs/env-vars.txt b/docs/env-vars.txt index 815a3098..0c15cbe9 100644 --- a/docs/env-vars.txt +++ b/docs/env-vars.txt @@ -78,6 +78,15 @@ Same as for __ALSOFT_REVERSE_Z, but for Y (up/down) panning. __ALSOFT_REVERSE_X Same as for __ALSOFT_REVERSE_Z, but for X (left/right) panning. +__ALSOFT_DEFAULT_ERROR +Applications that erroneously call alGetError prior to setting a context as +current may not like that OpenAL Soft returns 0xA004 (AL_INVALID_OPERATION), +indicating that the call could not be executed as there's no context to get the +error value from.
