For hi-res audio listening, I've been a heavy FLAC user for a number of years - most of my current non-streaming music catalog is now saved as FLAC files. If you're not familiar with the format, it's a lossless compression format unlike MP3, AAC, OGG Vorbis, etc. that are lossy and discard audio data during compression. Hence, the name Free Lossless Audio Codec (FLAC). Furthermore, the latest version, FLAC 1.5.0, is the first multithreaded version of the encoder, so it can make better use of hyperthreaded and multicore CPUs. By default, FLAC is accessed using the command line, but I've included a link for FLAC Frontend below, a GUI app that I make use of to create and extract FLAC file contents (used to convert WAV files to FLAC and vice versa). A link to download FLAC for Windows is below. Installers of FLAC for other platforms can be found here: https://xiph.org/flac/download.html

By default, the FLAC Frontend GUI app uses an older version of FLAC. Simply extract the contents of the FLAC 1.5.0 download for Windows (see link directly above) into the "Tools" folder of the FLAC Fronted installation, and it will use the latest version of FLAC.
