It uses a hybrid memory-disk storage model for low-latency ingestion and retrieval, enabling fine-grained access to arbitrary time ranges within large audio archives while minimizing disk I/O.\n\n## Features\n\n- **Format Conversion** — Transcode audio to PCM, WAV, Opus and MP3.\n- **Time-Range Queries** — Retrieve precise audio segments from large archives.\n- **Caching \u0026 Persistence** — Hybrid memory–disk storage with LRU caching.\n- **Programmability** — Embedded Guile Scheme interpreter for scriptable server interaction.\n- **Replication** — Basic master-slave replication.\n- **WAL** — Write-ahead log for crash recovery.\n\n## ⚠️ MVP Stage\n\nRACS is currently in the Minimum Viable Product (MVP) stage. It is under active testing. New features and enhancements will be added in future releases. Feedback is welcome!\n\n## Licensing\n\nRACS is distributed under the RACS Source Available License (RACS-SAL-1.0).  \nIt is free for personal, educational, and non-commercial use. Commercial use requires a paid license.
