Free music scales software for linux

Music Applet is a small, simple GNOME panel applet that lets you control Rhythmboxs playback from a panel.
Advantages that this applet has over using the icon Rhythmbox puts in the notification area include:
- One-click access to the main operations needed during playback, without needing to use a context menu.
- Display of the current playing time without requiring a mouse-over.
- Display of the current songs album in the song information.
Music Applet currently supports the following music players:
- Banshee
- Rhythmbox
Music Applet is the successor to Rhythmbox Applet.

Sonic Visualiser is an application for viewing and analysing the contents of music audio files.
The aim of Sonic Visualiser is to be the program you reach for when you find a musical recording you want to study rather than simply hear.
As well as a number of features designed to make exploring audio data as revealing and fun as possible, Sonic Visualiser also has powerful annotation capabilities to help you to describe what you find, and the ability to run automated annotation and analysis plugins in the new Vamp analysis plugin format.
We hope Sonic Visualiser will be of particular interest to musicologists, archivists, signal-processing researchers and anyone else looking for a friendly way to take a look at what lies inside the audio file.
Main features:
- Load audio files in WAV, Ogg and MP3 formats, and view their waveforms.
- Look at audio visualisations such as spectrogram views, with interactive adjustment of display parameters.
- Annotate audio data by adding labelled time points and defining segments, point values and curves.
- Overlay annotations on top of one another with aligned scales, and overlay annotations on top of waveform or spectrogram views.
- View the same data at multiple time resolutions simultaneously (for close-up and overview).
- Run feature-extraction plugins to calculate annotations automatically, using algorithms such as beat trackers, pitch detectors and so on.
- Import annotation layers from various text file formats.
- Import note data from MIDI files, view it alongside other frequency scales, and play it with the original audio.
- Play back the audio plus synthesised annotations, taking care to synchronise playback with display.
- Select areas of interest, optionally snapping to nearby feature locations, and audition individual and comparative selections in seamless loops.
- Time-stretch playback, slowing it down to as little as 10% of the original speed while retaining a synchronised display.
- Export audio regions and annotation layers to external files.
The design goals for Sonic Visualiser are:
- To provide the best available core waveform and spectrogram audio visualisations for use with substantial files of music audio data.
- To facilitate ready comparisons between different kinds of data, for example by making it easy to overlay one set of data on another, or display the same data in more than one way at the same time.
- To be straightforward. The user interface should be simpler to learn and to explain than the internal data structures. In this respect, Sonic Visualiser aims to resemble a consumer audio application.
- To be responsive, slick, and enjoyable. Even if you have to wait for your results to be calculated, you should be able to do something else with the audio data while you wait. Sonic Visualiser is pervasively multithreaded, loves multiprocessor and multicore systems, and can make good use of fast processors with plenty of memory.
- To handle large data sets. The work Sonic Visualiser does is intrinsically processor-hungry and (often) memory-hungry, but the aim is to allow you to work with long audio files on machines with modest CPU and memory where reasonable. (Disk space is another matter. Sonic Visualiser eats that.)

PyMusicD is yet another jukebox daemon written in python. It was born out of my frustration with the current mp3 jukeboxes, mostly the lack of features that I want. Ive also been playing with python quite a lot lately, and this is my first attempt at a large project in python.
The player is being written to satisfy my own requirements for a car mp3 player, although theres no reason you couldnt use this for a home mp3 player, or work mp3 player.
It assumes that your network users are (mostly) benign, and doesnt take a lot of precautions against malicious users who want to screw with your mp3s. Take appropriate measures to only allow trusted users to play with it, at least until I secure it a bit better.
Its primary purpose is to run in the background, and play mp3s whenever they are in the playlist.
Usage
Unpack this to its own directory. Edit the pymusicd.conf file to your liking. Run python PyMusicD, then run python pymusic to play around with it. The client operates very similarly to most shells, and includes tab completion for commands (but not arguments... yet.)
If you wish to install this to the system, you may do so by running python setup.py install. This will install the server binary in the default place for your platform (according to distutils.) You may then edit the config file (/etc/pymusicd.conf by default) and run the server by running PyMusicD. The cli client will be named pymusic.
This software is currently in development. It is not ready for end users yet. You should have familiarity with scripting in python before you set about to use this software. That being said, if you find bugs that arent listed in TODO, and/or have problems with the software that arent listed in TODO, email me (zwhite@darkstar.frop.org) and Ill see what I can do to help you. Code patches/suggestions are always welcome.
This is known to work on my Slackware 9.0 machine using the Python 2.2.2 package that came with it. I have also tested it on my Mac OSX 10.2.8 machine with Python 2.2. I have no reason to believe that it wont work on any machine with a Python 2.x interpreter and
either mpg123 or mpg321. Your mileage may vary. If it doesnt work on your platform, please let me know. My goal is to have this work on any platform that python runs on.
Enhancements:
- Fixed a bug when adding an entire directory with %2A instead of *
- Added a debug command to get server state, currently only playstatus is reported, will add more as needed.
- Changed the way the stop command works to eliminate a bug.
- Check to make sure a file exists before we add it to the playlist.
- We no longer start playing music as soon as the playlist has entries.
- Instead, we wait for a play command to be issued.
- Added config file support. Defaults to /etc/pymusicd.conf or ./pymusicd.conf
- Added a setup.py and setup.cfg file. Now users can install PyMusicD using the standard "python setup.py install" method that other scripts and modules use.

Music::Chord::Namer - You give it notes, it names the chord.

SYNOPSIS

use Music::ChordName qw/chordname/;

print chordname(qw/C E G/); # prints C
print chordname(q/C E G/); # same (yes, array or string!)
print chordname(qw/C Eb G Bb D/); # prints Cm9
print chordname(qw/G C Eb Bb D/); # prints Cm9/G

Music::ChordName optionally exports one sub, chordname, which accepts some notes as either a string or a list and returns the best chord name it can think of.

EXPORT

None by default.

$bestnamescalar|@namesarray = chordname($notesstring|@notesarray)
chordname() accepts either a string of notes such as "C Eb G A#" or a list of notes such as qw/Ab Bb F Bb D/. In a scalar context it returns the best name it could think of to describe the chord made from the notes you gave it. In an array context it returns all of the names it thought of, sorted from best to worst (shortest to longest!)

EXAMPLES

# to print a bunch of guitar chord names with at lest 4 notes each,
# all below 5th fret...

foreach my $s1(qw/- E F Gb G Ab/){
foreach my $s2(qw/- A Bb B C Db/){
foreach my $s3(qw/- D Eb E F Gb/){
foreach my $s4(qw/- G Ab A Bb/){
foreach my $s5(qw/- B C Db D Eb/){
foreach my $s6(qw/- E F Gb G Ab/){
my @notes = ();
push @notes, $s1 unless $s1 eq -;
push @notes, $s2 unless $s2 eq -;
push @notes, $s3 unless $s3 eq -;
push @notes, $s4 unless $s4 eq -;
push @notes, $s5 unless $s5 eq -;
push @notes, $s6 unless $s6 eq -;
if(@notes >= 4){
print scalar(chordname(@notes)), = ,join( ,@notes),"n";
}
}
}
}
}
}
}

Music Player Daemon (MPD) is a server that allows remote access for playing music (MP3, Ogg Vorbis, FLAC, AAC, Mod, and wave) and managing playlists.
Music Player Daemon makes a great desktop player with frontend options (Qt, GTK, ncurses, Windows, and Web clients are available). It is also appropriate as a console player that is scriptable, and is especially useful if X is restarted frequently.
A set of rapid development tools for clients are being developed and include a C library, Python module, PHP class, Perl module, and Java Class.
The goals are to be easy to install and use, to have minimal resource requirements, to be stable and flexible, and easy to interface.
MPD is designed around a client/server architecture, where the clients interact with MPD over a network. Thus, running MPD is only half of the equation; to use MPD, you need to install a MPD client:
Web Clients
- phpMp - Web interface written in PHP
- phpMp2 - Another web interface written in PHP
Graphical Clients
- gmpc - Gnome Music Player Client
- kmp - Graphical interface written in Qt
- MPDCon - A GNUstep Graphical interface
- glurp - Graphical interface written in GTK+
- WMmp - Window Maker dockapp
- gtk2mp - Try gmpc first! Graphical interface written in Gtk+
Command Line Clients
- ncmpc - ncurses (command line) client
- mpc - (Scriptable) command line client
- bashmp - client written as bash aliases and functions
Miscellaneous Clients
- mpcstick - Linux joystick client
- arthist - Perl client to generate a web blog of MPD activity

The Million Musician Challenge is a project to allow you to play music by playing games. The first game is a 2D vertically scrolling shoot-em-up game.

The keyboard (qwerty or musical) controls an array of sprites corresponding to the music notes. As you shoot the falling sprites, you play notes corresponding to the music.

Duplicate Music Matcher is a script to quickly find duplicate MP3 files based on letter matching.
Duplicate Music Matcher is helpful for weeding out duplicates that may not be of the same encoding, format, or even the same filename.
Enhancements:
- pymad pyvorbis python-flac deps were all removed in favor of mutagen
- GUI code was updated (no more SimpleGladeApp)
- Delete key have been bound in the GUI
- More accurate matching for ogg and flac files
- The filename column is now resizable
- The GUI play and stop buttons now use audacious.FLAC should now also give a length value
- Some oggs might have a huge bitrate value due to a bug in mutagen.
