PM3 Audio Converter

The PM3 Audio Converter accepts PM3 format inputs and provides outputs in MP3, WAV, FLAC, or OGG. It preserves essential metadata and supports optional resampling, bitrate control, and channel remapping. Conceptually, the tool decodes the PM3 data, applies format-appropriate encoding with user-specified quality parameters, and re-packages metadata into standard fields. Beneficiaries include archivists migrating libraries, musicians preparing masters, and researchers compiling datasets. Its unique value lies in per-file consistency, metadata fidelity, and batch processing capabilities that minimize manual re-encoding tasks. Core features include PM3 decoding, multi-format encoding, metadata mapping, and configurable quality presets. Use cases range from archival digitization to preparing distribution copies for streaming platforms. In production, it reduces time-to-delivery while preserving provenance and tag data. Core logic emphasizes deterministic processing, robust error handling, and compatibility with ID3 and Vorbis metadata schemas.
