Liquidprism announced on X that it is developing an open‑source library capable of converting arbitrary consumer devices into a state‑of‑the‑art ad‑hoc 3‑D spatial microphone array. The tweet links the project to a call for volunteers who have spare devices to test the system liquidprism's tweet.
How the library works
The code plans to treat each device’s built‑in microphone as a node in a distributed array. By synchronizing audio streams and applying spatial processing algorithms, it can reconstruct a three‑dimensional sound field without dedicated hardware. The approach leverages existing APIs for audio capture on smartphones, laptops, and IoT speakers.
Practical benefits for startups
For teams building voice‑enabled products or immersive audio experiences, the library could reduce hardware costs. Instead of buying a multi‑mic array, developers can prototype with devices already on hand, accelerating early‑stage testing. The open‑source license also avoids vendor lock‑in.
Risks and limitations
The project is in its infancy, so calibration may be noisy, especially when devices differ in sample rates or have varying microphone quality. Real‑time synchronization across Wi‑Fi or Bluetooth can introduce latency, limiting use cases that require low‑delay capture. Additionally, the need for “arbitrary consumer devices” means you must manage a heterogeneous hardware pool, which can complicate testing and maintenance.
When to try it
If your team is experimenting with spatial audio and can allocate a handful of spare phones or tablets, clone the repo and run the demo to gauge signal‑to‑noise ratios. Watch the project’s GitHub activity for a stable release and documentation updates before committing to production use.
What to watch: upcoming benchmark results and community contributions that address cross‑device synchronization and calibration pipelines.
