Audio Latency Tool

The tool provides end-to-end latency measurement for audio processing chains, enabling developers and QA teams to quantify delay from input to output across software and hardware stages. It supports configurable test signals, multiple sample rates, and adjustable buffers, making it suitable for CI benchmarks and ad-hoc experiments. Conceptually, the system timestamps emission and reception events with high-resolution clocks, then computes latency and jitter across runs. Users can enable per-stage reporting to isolate delay contributions from interfaces, drivers, or plugins. The workflow is deterministic: set test parameters, run measurements, inspect results, and compare scenarios. The tool is suitable for audio interfaces, digital signal chains, and game audio paths where timing is critical, and it differentiates itself through precise drift correction when using external clocks and by exporting structured results for programmatic analysis. It supports multi-channel configurations and integration into automated test suites, enabling reproducible latency footprints across software updates or hardware changes. Core value lies in reducing unexpected latency spikes, informing buffer sizing decisions, and validating real-time performance under varying CPU loads. Typical use cases include benchmarking USB audio interfaces, evaluating plugin chains for latency-sensitive monitoring, and CI validations of audio middleware. Outputs include millisecond latency, jitter, and percentile statistics (50th/95th/99th), with optional per-stage breakdown for deeper analysis. Export options facilitate downstream analytics and dashboards.
