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
