About:
Libaec is a free software library implementing the Golomb-Rice adaptive entropy coding algorithm. It provides lossless compression for scientific and other data, offering high compression ratios for floating-point and integer data. The library serves as a fast and efficient alternative to standard compression methods for specialized datasets.

Key Features:

Implements Golomb-Rice adaptive entropy coding
Optimized for high-performance compression/decompression
Provides a BSD-style license for permissive use
C library with a stable API for integration

Use Cases:

Compressing large-scale scientific datasets and simulation output
Reducing storage requirements for satellite and climate data
Integrating efficient lossless compression into custom C/C++ applications

Alternatives:

zlib – General-purpose DEFLATE compression, often less effective on specific scientific data types
bzip2 – Block-sorting compressor, typically slower and uses more memory than Libaec
