DSD Audio Converter

This tool enables precise conversion of Direct Stream Digital (DSD) audio between DSD formats or to PCM. It accepts input files in DSD64/128/256/512 and outputs in the same format or PCM at user-selected sample rates. The system is designed for audiophiles, mastering engineers, and archival staff needing high-fidelity format compatibility. Conceptually, DSD streams are delta-sigma modulated; the converter applies rate-change filters and reconstruction paths to reach the target format, with optional dithering to preserve dynamic range on PCM outputs. The tool supports batch processing, multiple output containers (WAV/FLAC/AIFF), and metadata passthrough, enabling efficient workflows for large libraries. Unique value lies in configurable dithering profiles and high-precision rate-change filters that minimize audible artifacts during format shifts. Typical use cases include archiving a DSD collection into PCM for streaming catalogs or converting a master DSD to a DAC-friendly rate. Core features include: input/output format selection, target sample rate and bit depth for PCM, DSD-rate conversion, optional dithering, and metadata passthrough. This tool does not normalize loudness or alter content beyond format conversion and optional dithering; it focuses on fidelity-preserving translation between formats and rates.
