OptimFROG

OptimFROG is a lightweight audio package that contains codecs for helping you obtain lossless audio compression results. It is specifically developed to help you reduce at maximum the size of audio items, while preserving the audio quality as much as possible.
The process is pretty much similar to ZIP compression, but the tool works exclusively with audio files. The audio codec can be deployed on Windows, Linux, and Mac versions.

Compatibility with several media players (direct playback of OptimFROG files)

OptimFROG offers support for fully-featured input plugins for Windows Media Player, foobar2000, Winamp 2/3/5, dBpowerAMP, XMPlay, QCD, and XMMS audio players (with bit stream error resilience, ID3v1.1 and APEv2 read tagging support, ID3v2 compatible).
Several media players are known to be compatible with OptimFROG, such as Audacious, AudioNUT, DeaDBeeF, DirectShow Decoder Filter, Passion Audio Player, lamip, Qmmp, RadLight 4, MusicCubeOne, and Zoom Player.
In addition, it works hand in hand with various utilities, namely AudioMagus (organize OptimFROG files), BASS (audio decoder library with support for OptimFROG items), Burrrn (create audio CDs directly from OptimFROG files), EAC / Exact Audio Copy (extract audio CDs in OptimFROG format), getID3() for extracting useful information about OptimFROG files, GX::Transcoder (transcode directly from OptimFROG files), Kermit (Windows frontend interface for OptimFROG), and Mp3tag (manage tags for OptimFROG files).
It also comes with support for MPC / Musepack (direct encode mode from OptimFROG files), MPEG Audio Collection (organize OptimFROG files), Music Collector (organize OptimFROG files), MusicBrainz Picard (manage tags for OptimFROG files), Nero audio plugins (create audio CDs directly from OptimFROG files), Perl Audio Converter (transcode from OptimFROG files), and Tag (command-line tagging tool for OptimFROG files).

Audio compression capabilities

OptimFROG comes packed with several smart and handy features, such as optimal support for all integer PCM WAV formats up to 32 bits, RAW file support, and encoding and decoding options. Plus, you can verify the integrity of the compressed files, process multiple files at the same time via the command-line console using wildcards, and delete the source file at the end of a successful task.
What’s more, you are allowed to copy the time stamp of the source file to the destination item, create self-extracting archives (SFX file format), as well as make use of a rich-featured SDK for employing the compressed files in any program.

Final remarks

To sum things up, OptimFROG proves to be a reliable audio codec that helps you achieve one of the best lossless audio compression ratios. It is all worthy of your attention.
