Pegasus/KrishnaSoft Sound Processing Software

Pegasus SPS Sound Processing Software (SPS) was developed by KrishnaSoft as a general purpose audio editor. It features a lossless compresion mode based on Pegasus' ELS (Entropy Logarithmic Scale) compression algorithm.

The editor itself has very few features and a quite strange interface. It includes a minimalistic and weird player to play compressed .SDB (sound database, their lossless format) files; and a batch compression/decompression tool. Being a Windows 3.1 program it has no support for long file names.

The lossless compression performance is nothing to get excited about, it is quite slow (maybe in part because it is 16-bit code?) and performs worse than WavPack or FLAC.

But, from the looks of it, it is free - only the lossless compression is limited to 10 uses, and after that you need to buy a license.

The page about SPS at Pegasus is now gone (but still mirrored at the Internet Archive) and it seems that Pegasus themselves vanished. But you can still find it - and buy it! - at Krishna Software.

Compression performance in my limited test: 57,68% (setting ELS Ultra)
