CRYSTAL-ASIO-Codec v1.0.0

Advanced Cross-Platform Real-Time Audio Driver & Codec

---

🌟 Overview

Crystal-ASIO-Codec is a high-performance, low-latency cross-platform audio driver and streaming codec designed for professional audio engineering environments. Built from the ground up with C++20, it prioritizes rigorous real-time safety, deterministic execution, and complete privacy with zero telemetry or tracking SDKs.

---

⚙️ Core Architecture & Components

• Opus Codec Integration (src/opus_codec.cpp): High-efficiency audio compression and decompression for streaming workflows.
• Real-Time Guard (src/rt_guard.cpp): Protects audio callback threads against priority inversions, blocking operations, and allocation.
• Lock-Free Audio Ring Buffer (src/audio_ring_buffer.cpp): Thread-safe buffering optimized for multi-track scaling and low-latency.
• Sample Conversion & Channel Mapping (src/sample_convert.cpp, src/channel_map.cpp): Flexible routing and format conversions for varied hardware layouts.
• Telemetry Diagnostics (src/telemetry.cpp): Localized performance metrics capture without external data transmission.

---

🖥️ Platform Backends

• Windows (src/windows/):
  • Full ASIO driver implementation (crystal_asio_driver.cpp).
  • WASAPI audio hardware backend (wasapi_backend.cpp).
• macOS (src/macos/):
  • CoreAudio HAL plugin integration (crystal_hal_plugin.cpp).
  • Automated installation helper scripts (scripts/install_macos.sh).
