As I barge through the Lossless Compression Performance Test, I realized that only WavPack provides a progress indicator while operating in quiet mode, in the form of "xx% (WavPack)" replacing the command-line Window's title.

IMO this is a nice feature. Perhaps this is not *that* useful, but since I compress a multitude of files using batchfiles, I force all compressor to run in silent/quiet mode, redirecting them to nul if the compressor does not provide a quiet mode (Lossless Audio: shame on you... ) Of course this means I lost the progress bar, and is left wondering how the compression has progressed. Except for WavPack.
