OpenAL only spatializes mono buffers; stereo buffers play as fixed ambient beds. This guide explains the constraint, shows a verification test, and provides a checklist for correct asset preparation.
OpenAL initialization succeeds with AL_NO_ERROR but no sound plays. This diagnostic guide covers device mismatch, thread-local context, zero gain, unsupported formats, streaming underruns, and hot-plug handling with ordered checks, fixes, and a minimal sine-wave verification test.
Use AL_SOURCE_RELATIVE to lock menu and UI sounds to the listener while keeping 3D game audio in world space.
Learn how to set up listener‑source relationships, choose a distance model, and apply Doppler shift in OpenAL with a concrete C example and verification steps.
Silent reverb in OpenAL Soft is usually an extension or attachment failure, not a parameter problem. This guide shows how to check AL_EXT_EFX presence, effect creation, slot attachment and resource limits.
Learn how to implement 3D spatial audio in OpenAL by managing listener orientation and choosing the right distance attenuation models for realistic sound decay.
Learn how to queue PCM buffers to an OpenAL source for gap‑free, low‑latency playback, including setup, loop, error checks, and recovery steps.
Learn how to turn on OpenAL Soft’s HRTF, why it matters for realistic 3‑D audio, the performance trade‑offs, and a ready‑to‑copy code example that lets you toggle the feature at runtime.
Learn how to add realistic reverberation to 3D game audio using OpenAL Soft’s built‑in reverb effect, with a minimal code sample and performance tips.
