RompЯ is a music player with the emphasis on discovery – discovering more about the music you know, and discovering new music you don’t know yet. RompЯ is an interface that runs in a web browser on any device and controls a music player which can be on any other device. I recommend using Mopidy as the music player. When used with Mopidy and a Spotify Premium subscription RompЯ is a powerful Spotify client with many music discovery features.

Dynamic Audio Normalizer is a library for advanced audio normalization purposes. It applies a certain amount of gain to the input audio in order to bring its peak magnitude to a target level (e.g. 0 dBFS). However, in contrast to more “simple” normalization algorithms, the Dynamic Audio Normalizer dynamically re-adjusts the gain factor to the input audio. This allows for applying extra gain to the “quiet” sections of the audio while avoiding distortions or clipping the “loud” sections. In other words: The Dynamic Audio Normalizer will “even out” the volume of quiet and loud sections, in the sense that the volume of each section is brought to the same target level. Note, however, that the Dynamic Audio Normalizer achieves this goal without applying “dynamic range compression”. It will retain 100% of the dynamic range within each “local” region of the audio file.
The Dynamic Audio Normalizer is available as a small standalone command-line utility and also as an effect in the SoX audio processor as well as in the FFmpeg audio/video converter. Furthermore, it can be integrated into your favourite DAW (digital audio workstation), as a VST plug-in, or into your favourite media player, as a Winamp plug-in. Last but not least, the “core” library can be integrated into custom applications easily, thanks to a straightforward API (application programming interface). The “native” API is written in C++, but language bindings for C99 Microsoft.NET, Java, Python and Pascal are provided.

JACK Audio Connection Kit – Qt GUI Interface: A simple Qt application to control the JACK server daemon. Written in C++ around the Qt framework for X11, most exclusively using Qt Designer. Provides a simple GUI dialog for setting several JACK server parameters.

ANMP aims to be a versatile but lightweight audio player, just as the other hundred thousands out there. It is written in C++11. As being only a frontend, ANMP itself doesn’t know anything about audio formats and how to decode them. That’s why it uses 3rd party libraries to decode them. By using VgmStream, GameMusicEmu, LazyUSF and supporting looped songs natively, ANMP is esp. suited to play various audio formats from video games. Moreover it supports Looped Midi Tracks.
Main Features:
- muting multichannel audio files
- gapless playback (for most streamed audio formats)
- arbitrary (forward) looping of songs (i.e. even nested loops)
- synthesizing MIDI files using fluidsynth
- multi-channel audio rendering
- overlapping notes do not kill each other
- unrolling looped MIDI tracks
- volume response compatible to N64’s software synth
- supports an IIR lowpass filter compatible to Rareware‘s N64 games (Conkers Bad Fur Day, Jet Force Gemini)
- support for cue sheets
- support for audio normalization based on EBU R 128
- exposes basic commands via D-Bus

GrandOrgue is a sample based pipe organ simulator. When connected to MIDI keyboards and an audio system, it can accurately simulate the sound of a real pipe organ. This application has builds for Linux, Windows and OSX.
Features:
- Play sample sets
- GUI console

ABC, developed by Chris Walshaw, is a format designed to notate music using plain text. It was originally designed for folk tunes of Western European origin which can be written on one staff, but has since been extended to support the notation of complete, classical music scores.
Since its introduction at the end of 1991, ABC has become very popular. Programs on many operating systems use ABC as an input and/or output format. There are programs which produce printed sheet music or allow for computer performances, search in tune databases, or that analyze tunes in some way.
The aim of this project is to promote the ABC language by maintaining the ABC standard and a set of software and source code that manipulate and present music written in ABC.

The abc tune search / tune finder gives you access to thousands of folk & traditional tunes from across the web.

Mikmod is a module player and library supporting many formats, including mod, s3m, it, and xm. Originally a player for MS-DOS, MikMod has been ported to other platforms, such as Unix, Macintosh, BeOS, and Java(!!)

Streamripper was started sometime back in early 2000. Streamripper started as a way to separate tracks via Shoutcast’s title-streaming feature. This has now been expanded into a much more generic feature, where part of the program only tries to “hint” at where one track starts and another ends, thus allowing a mp3 decoding engine to scan for a silent mark, which is used to find an exact track separation.
Streamripper is now part of the FreeBSD standard distribution, mentioned in the Linux MP3 HOWTO, known to compile on many platforms such as Linux, Windows, FreeBSD, BeOS, OS/2. This is not surprising as portability was a constant consideration during development.
Streamripper allows you to download an entire station of music. Many of these mp3 radio stations only play certain genres, so you can now download an entire collection of goa/trance music, an entire collection of jazz, punk rock, whatever you want.
