MQA Decoder

The MQA Decoder analyzes input audio data to verify MQA encoding, extract frame markers, sampling rate hints, and authentication flags. It accepts common audio containers or raw data, then applies domain-specific parsing to distinguish genuine MQA content from non-MQA material. Outputs include a decoded status, detected sample rate, channel configuration, and a structured result suitable for QA workflows and archival validation.
Conceptually the tool performs sequential bitstream parsing, marker detection (MQA tags, frame syncs), and per-frame interpretation of decoded layers. It does not modify the source file or perform playback. Instead it returns a machine-readable summary, confidence scores, and optional logs that feed downstream audio analysis, cataloging, reporting, or compliance verification.
Who benefits: audio engineers, archivists, broadcasters, and researchers who need fast verification, repeatable metadata extraction, and auditable results. The tool supports batch processing for large catalogs, spot checks during ingest, and targeted investigations of suspected decodes, helping enforce quality control in production pipelines.
Core differentiators include strict adherence to MQA framing rules, clear decodability indicators, and easy export formats (JSON/CSV) for interoperability with other tools. Use cases span catalog QA, metadata extraction for metadata-driven workflows, and regulatory compliance checks in broadcast and streaming environments.
