Mp3tag is a powerful and easy-to-use tool to edit metadata of audio files.
It supports batch tag-editing of ID3v1, ID3v2.3, ID3v2.4, iTunes MP4, WMA, Vorbis Comments and APE Tags for multiple files at once covering a variety of audio formats.
Furthermore, it supports online database lookups from, e.g., Discogs, MusicBrainz or freedb, allowing you to automatically gather proper tags and download cover art for your music library.
You can rename files based on the tag information, replace characters or words in tags and filenames, import/export tag information, create playlists and more.

Convolver is an open source, high performance Windows application for applying finite impulse response (FIR) filters to multi-channel digital audio in the form of
- a real time DSP audio plug-in (DMO) for Windows Media Player. The install package also contains
- two DirectX / DirectShow filter versions — ConvolverWrapper or the equivalent ConvolverFilter — for Adobe Audition and real time applications such as Zoom Player Pro, TheaterTek 2.2, Windows Media Player Classic, J.River Media Center (when used with the DirectX host plug-in), or Console. See the setup walkthrough for ZoomPlayer after reading this page for further details. In many cases the DMO will also work.
- a VST plug-in version (convolverVST). Finally, there are a number of
- command line applications for testing performance, and convolving files offline, for example. convolverPipe can filter SlimServer playback.
Convolver will take a set of FIR filter files (sound files) and convolve them with sound paths mixed from the input channels, mixing the results into a set of specified output channels.

DRC is a program used to generate correction filters for acoustic compensation of HiFi and audio systems in general, including listening room compensation. DRC generates just the FIR correction filters, which can be used with a real time or offline convolver to provide real time or offline correction. DRC doesn’t provide convolution features, and provides only some simplified, although really accurate, measuring tools.

Date and duration adjusted (DADA) auto-rating algorithm for foobar2000
The DADA Auto-Rating algorithm (DAR) automatically rates music according to a variety of statistics collected by foobar2000’s official “playback statistics” plugin.If done well, an auto-rating algorithm will simply tell you what your favorite (and conversely, least favorite) music is, and the rating will be derived from and reflect actual listening behavior. This is quite different from manual ratings (e.g. 1 – 5 stars set by the user), since there’s very often a disparity between what we’d like ourselves to like, and what we actually like. For those interested in uncovering their actual musical tastes, a good auto-rating formula can be quite illuminating.

FLAC stands for Free Lossless Audio Codec, an audio format similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo) just like you would a MP3 file.
FLAC stands out as the fastest and most widely supported lossless audio codec, and the only one that at once is non-proprietary, is unencumbered by patents, has an open-source reference implementation, has a well documented format and API and has several other independent implementations.

Winamp — It really whips the llama’s ass!
The classic alternative to Window Media Player. Winamp is a cross platform, extensible, free and skinnable media player with a large community and a long past. Development has stopped, but may start again, meanwhile, the development community has largely moved to Foobar2000.

(Update) October 2018
A leaked version of Winamp 5.8 recently spread over the Internet. Consequently, we have decided to make this new version available to you, revised by us.

MilkDrop is a music visualizer – a “plug-in” or extension to Winamp or Foobar2000 music players. As you listen your music in Winamp, MilkDrop takes you flying through the actual sound waves you’re hearing, and uses beat detection to trigger myriad psychedelic effects, creating a rich visual journey through sound. MilkDrop can also be driven by a live audio feed (microphone or line-in).

MusicBrainz Picard is a cross-platform (Linux, macOS, Windows) audio tagging application. It is the official MusicBrainz tagger.
Picard supports the majority of audio file formats, is capable of using audio fingerprints (AcoustIDs), performing CD lookups and disc ID submissions, and it has excellent Unicode support. Additionally, there are several plugins available that extend Picard’s features.

Youtube: What is MusicBrainz Picard?
A Mac application for ripping high quality audio files from CDs. Integrated with MusicBrainz.
macOS 10.7 or greater.
Main site is 404, source code needs to be compiled. Any takers? Let me know.
CUERipper is an utility for extracting digital audio from CDs, and an open-source alternative to EAC. It has a lot fewer configuration options, so it’s somewhat easier to use, and is included in the CUETools package.
Supports AccurateRip, CTDB, freeDB and MusicBrainz
