ADC – Audio Codec for lossy Compression - 

Description:
ADC (Adaptive Differential Codec) is a custom-developed audio compression algorithm designed to achieve exact byte-for-byte preservation when encoding and decoding under fixed parameters. It enables perfect regeneration of the original waveform across multiple generations of recompression, provided the same encoding setting is used. 

Unlike traditional lossy codecs, ADC supports both hybrid and deterministic modes, allowing precise audio editing and long-term archival. This feature is particularly useful for educational recordings, archival work, or session-based editing, where concatenated streams retain bit-exact fidelity without re-encoding distortion.

This release includes documentation, reference test files, and specification of the codec’s design rationale. The implementation is currently distributed under a custom closed-source license for demonstration and academic review only.

Note: 

To get the exact match you should not activate the "-h" option which creates another lossy version.
