Zstandard, often abbreviated as Zstd, is a fast compression algorithm developed by Facebook. It is designed to provide a high compression ratio while maintaining fast compression and decompression speeds, making it suitable for a variety of applications including data storage, transmission, and real-time systems. Some key features of Zstd include: 1. **High Compression Ratios**: Zstd is capable of compressing data significantly, similar to other algorithms like zlib and LZMA, but often with better performance.
The Μ-law algorithm, also known as Mu-law companding, is a method used primarily in telecommunications to optimize the dynamic range of audio signals for transmission. It compresses the amplitude of audio signals to reduce the bit rate required for digital transmission while still maintaining audio quality. This technique is especially common in North America and Japan for PCM (Pulse Code Modulation) systems. The Μ-law algorithm applies a compression curve to the amplitude levels of audio signals before digitization.
