openalConfiguring and Verifying OpenAL Distance Models for Predictable 3D Audio Attenuation
Learn how to select and verify OpenAL's built-in distance models for consistent 3D audio attenuation, with a minimal C example and error‑checking steps.
Which OpenAL distance model behavior applies to existing sources after a global change?
When developing a 3D audio scene with OpenAL, the global AL_DISTANCE_MODEL setting determines how source‑listener distance is converted into attenuation. The specification notes that the distance model is a global state, implying that a change affects all active sources, but it does not clarify whether the attenuation curve is recomputed instantly for source
OpenAL 1.1 AL_MAX_DISTANCE boundary and source count limits
Goal Determine whether AL_MAX_DISTANCE produces consistent inaudibility behavior and whether simultaneous source creation limits are portable across OpenAL implementations. Constraints The OpenAL 1.1 specification leaves maximum simultaneous source count and exact attenuation rounding to the implementation. AL_MAX_DISTANCE does not define a universal silence
