OpenAL 2070: A Forensic Analysis of the Last Free, Open-Source Audio Middleware in a Post-IP Audio Landscape
OpenAL 2070 proves that free and open audio middleware remains viable even in a patent-saturated future. Its simplicity becomes a feature: predictable, auditable, zero-cost. We recommend that the Free Sound Foundation adopt a “retro-audio” exemption for legacy LGPL libraries. The source and 2070 binary are released at audio-legacy.openal-2070.holo (DOI: 10.2070/OPENAL-FREE).
Future hardware (2070) will be non-blocking and massively parallel. Use alGenSources with a queue system (alSourceQueueBuffers). Avoid busy-waiting loops. Write your audio logic as if you have infinite threads available. openal+open+audio+library+2070+free
The "Free" library of 2070 will allow users to inject their own HRTF data (or brain scans). Use OpenAL Soft’s built-in makehrtf utility, but store your impulse responses as raw, unencrypted text files. This ensures that in 2070, your audio will render correctly on a listener's unique biological ears.
We validated three freedoms (based on 2035 Libre Audio Charter): | Freedom | OpenAL 2070 | Proprietary 2070 middleware | |---------|-------------|-----------------------------| | Modify source | Yes (LGPL) | No (neural blob) | | Offline use | Yes | No (requires cloud attestation) | | Commercial use without per-sound fee | Yes | No (per-sound neural watermark) | OpenAL 2070: A Forensic Analysis of the Last
