Audio Test Tool

The Audio Test Tool analyzes an input audio signal to produce objective quality metrics for loudness, spectral balance, and signal integrity. It supports uploaded audio files and streaming inputs, and outputs standardized measurements that QA, mastering engineers, broadcasters, and product teams rely on to verify playback quality across devices and formats.
Core approach encompasses LUFS loudness (ITU-R BS.1770-4) calculation, peak and true-peak levels, and multi-band frequency response. It also estimates signal-to-noise ratio and distortion proxies by comparing analyzed segments to references. The design emphasizes repeatable results, auditability, and scalable processing.
Unique value lies in multi-format compatibility, batch processing, and exportable reports that integrate into QA pipelines. It supports CSV and JSON exports, time-aligned traces, and reference-level calibration to help meet broadcast and streaming standards without manual rework.
Common use cases include pre-release checks for content libraries, device and encoder validation, and performance benchmarking across players and environments. The tool provides objective metrics that help teams quantify improvements, justify decisions, and document compliance.
