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.

Foobar2000 ~ DADA Automatic Song Rating
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 ~ Free Lossless Audio CODEC
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 ~ Popular Extensible Music Player
Winamp β 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 ~ Audio Visualization Plugin
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).

foo_input_usf ~ Foobar Plays Nintendo 64
foo_input_usf is an input plugin for Foobar2000.
USF is a format which allows emulation of the sound of an Nintendo 64, which would allow (almost) perfect replication of the music in games. USFs are then played through a player, with a suitable plugin, which allows it to be played.
MusicBrainz Picard ~ Tag Files With MusicBrainz Metadata
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.
Features:
- Multiple formats: Picard supports all popular music formats, including MP3, FLAC, OGG, M4A, WMA, WAV, and more.
- AcoustID: Picard uses AcoustID audio fingerprints, allowing files to be identified by the actual music, even if they have no metadata.
- Comprehensive database: Picard uses the open and community-maintained MusicBrainz database to provide accurate information about millions of music releases.
- CD lookups: Picard can lookup entire music CDs with a click.
- Plugin support: If you need a particular feature, you can choose from a selection of available plugins or write your own.
- Scripting: A flexible and powerful, yet easy to learn, scripting language allows you to exactly specify how your music files will be named and how the tags will look like.
- Cover Art: Picard can find and download the correct cover art for your albums.
- Open Source: Picard is licensed under the GNU General Public License 2.0 or later, and is hosted on GitHub where it is actively developed.

MusicBrainz ~ The Open Music Encyclopedia
MusicBrainz is an open music encyclopedia that collects music metadata and makes it available to the public.
MusicBrainz aims to be:
- The ultimate source of music information by allowing anyone to contribute and releasing the data under open licenses.
- The universal lingua franca for music by providing a reliable and unambiguous form of music identification, enabling both people and machines to have meaningful conversations about music.
- Like Wikipedia, MusicBrainz is maintained by a global community of users and we want everyone β including you β to participate and contribute.
