WavPack

WavPack is a tiny utility, but that packs powerful functions to help you process and convert open audio compression formats. Not only can it ensure a lossless format, but it also comes with a unique hybrid compression mode.

The setup is as easy as it gets and it entails decompressing the archive and then accessing the application via the Command Line. As you probably hinted, the tool does not have an interface per se, but rather you need to be familiar with the standard console in Windows to use it.

While it addresses mostly advanced users, you should bear in mind that you can find ample documentation on how to use it along with a manual on the developer's website. It is worth mentioning that the application comes with a complementary app, WvUnpack, that can help you compress and restore audio files in several formats.

Despite the fact that it lacks a user-friendly interface, the program compensates via its advanced options.  Consequentially, you can engage in transcoding with a single command, make sure the file is checked after it has been processed or create an enhanced compression by checking the optional asymmetrical mode, just to name a few.

On the other hand, you should know that the utility can process a limited number of audio files, namely  DSF, CAF, WV, DFF, W64, and WAV. While the default conversion mode is lossless, you can modify it to the quality that is most suitable for your needs.

In the eventuality that you are looking for a tool that allows you to manipulate various parameters of your audio files more accurately and you are not deterred by the command-line interface, then perhaps WavPack could lend you a handy.
