Decoder: converts DSD audio from DSF files to PCM format. Encoder: converts PCM audio to DSD and writes DSF files.

Key features:

• DSF file header parsing, validation, and generation
• Correct block-level channel de-interleaving per DSF spec
• DSD-to-PCM via bit counting with cascaded Butterworth anti-aliasing
• PCM-to-DSD via 2nd order delta-sigma modulation with interpolation
• Streaming-compatible operation for real-time processing
• Support for mono and multi-channel DSD files (DSD64 and higher)
