Audio routing tool

The tool models routing graphs by defining a set of inputs, outputs, and the matrix that maps sources to destinations. It captures constraints such as sampling_rate_hz and latency_ms to ensure feasible paths and to prevent dropouts. Users include live engineers, studio techs, and developers integrating routing logic into automation scripts.
Conceptually, a path consists of a source input, optional processing blocks (gain, pan, or simple delay), and a destination output. The routing_matrix encodes which paths are active and the tool computes aggregate metrics like total_latency_ms, per-path gain, and channel utilization. Validation highlights missing links, conflicts, or cycles that could cause feedback.
Benefits include repeatable configurations, faster setup, and documented signal flows for audits or future changes. It supports scenarios such as front-of-house routing for live events, broadcast chain design, or studio mixing where multiple inputs converge to a controlled set of outputs. Presets enable rapid reuse across gigs.
Core features include input/output definitions, a scalable routing matrix, constraint checks, conflict detection, and diagnostic reports. Advanced users can load presets, compare scenarios, simulate traffic, and export JSON or CSV representations for integration with automation tools or DAWs.
