Free songs software for linux

Songs is a graphical tool to record and mix audio files. It supports an infinite number of tracks, huge audio files, and various effects.
One important motivation for Songs was the need of a recording tool under Linux. There are some already existing (see the links below), but these are too complex, too huge, eat too much memory and resources. Small machines can be used to record and mix audio files, even with a graphical interface. Songs is trying to prove it.
The recording is done directly to disk, so that with small machines, whithout much memory you can still record.
There is a full duplex mode, but full duplex is not very well handled with OSS. You dont really know if your two streams of samples are synchronized or not, and the interface provided by OSS does not help much with that. So, currently, take the full duplex mode as is. You probably will need to move by hand audio tracks to let them be synchronized.
Main features:
- Unlimited number of tracks.
- Supports WAV files (mono, stereo). Only 44.1 KHz, 16 bits files are supported, because Songs was born mainly to help me create music I could store on audio digital compact disks.
- Supports raw float files (mono, stereo). Very useful when you are mixing and that you eat too much resources. Simply put in a new file your current mix, and use this new file instead of several ones. Using float numbers gives more precision of the intermediary mixing.
- Several effects (currently not that much, but it is planned).
- Not too much memory used. All the audio files are mapped directly into the memory, so that the Linux kernel can swap them very easily. It means that if your files can exist on your disk, any size they are, they can be used with Songs (with a soft limitation of virtual memory space, which depends on your setup, and a hard limitation of 2 GB, because of the use of signed integers, which currently are 32 bits numbers).
- Use of gtk 2.0, for the good and the bad. The good is that the interface was done quickly. The bad is that the gtk documentation is far from perfect, that gtk is not bug free, that I may use it the wrong way sometimes and that it may change in the future, forcing Songs to be changed (and what if the Songs authors dont feel the need to do so, for example by lack of time?).
Enhancements:
- sc1.c sc1_gui.c:
- New files, ripping a compressor from sc1_1425 coming from swh-plugins-0.4.11.tar.gz (see http://plugin.org.uk/).The compressor was buggy, sometimes in rms_env_process
- r->sum was negative, leading to NaN for the sqrt stuff.
- pan/vol/pos.c: Checking return value of malloc (no, it was not done, shame !).
- various files: Fixing a realloc misusing (doing realloc(size+=32) then size+=32, which finally means size+=64 but only allocing size+32 stuff, weirdy to find).
- help_gui.c: The "About" stuff only appeared once, fixing it.
- various files: Fixing bugs those last days, forgot to feed this Changelog.

qSong project is a song database and a lyrics manager program with multimedia features.
Main features:
- Store and manage song lyrics
- One ssong can have multiple versions
- Song can have related songs
- Copyright information - authors and ccli
- Comprehensive authors database
- Attachment of multimedia files (sound files, picures, tabs...)
- Searching and sorting songs in many cathegories using tree view of the database
- Grouping songs in songbooks
- Every item in database can have comments
qSong is written in C++ with Qt4 library. It uses SQlite3 as a database backend so it is easy to acces the song database in standard way by 3rd party SQL tools through database intercaces as ODCB or JDBC.
I have chosen this platform because is very portable, relatively fast and easy to extendable with plugins.

Per-Song Volume is a Perl script maintains a per-song volume information.

What it means is that a volume is associated with each song, which is recorded whenever the volume changes, and is restored to its last value when the song is played again.

This is useful if you have several songs which sound louder or softer than the rest.

To run this script you need perl 5 and DBD::SQLite (http://search.cpan.org/dist/DBD-SQLite/).

The file "$HOME/.kde/share/apps/amarok/scripts-data/per-song-volume.default-volume.txt" can optionally hold the default volume for playing the files (an integer from 0 to 100). The default setting for it is 40.

I hope you find this script useful!

KMusicManager manages your entire music collection.
Main features:
The music collection view
- The main collection view shows an overview of your entire music collection. At the top of the view theres a search bar. Entering text here will only show those songs which have the search text in one of their properties.

The playqueue
- Feel like listening to some songs, just drag them to the playqueue. Want to rearrange the songs in the playqueue, just drag them around.
- Whenever KMusicManagers player needs a song, it will first look into the playqueue. If it finds some songs in the queue, it will grab the first and play it. If the playqueue is empty, it will try to find a song in the current playlist.
The database tree
- The database tree gives you an overview of your entire music collection. It shows a directory tree of all the directores in your music database.
The file renamer
- You can easily rename files with the file rename feature, so that all your music files are named consistently. The file renamer also allows files to be put in separate directories, it will take care of directory creation for you.

mp3CONVERT is a Kommander wizard for easy encoding mp3 songs. For example, when you need get your favourite album, which has 100mb to the cell phone with 40mb memory.

Moosic is a music player for Unix systems. It focuses on convenient and powerful playlist management. This project consists of a server process that maintains a queue of songs to be played and one or more client programs which sends commands to the server.

The server continually runs through its song queue, popping songs off the top of the list and playing each with an external program. The client is a simple command-line utility which allows you to easily perform powerful operations upon the servers queue, including the addition of whole directory trees, automatic shuffling, and song removal according to regular expressions.

The server comes configured to play MP3, Ogg, MIDI, MOD, and WAV files, but can be configured to also play any other file format you want.

Headphone is an amaroK script that offers a Dj-ing feature. You can send one or more songs from the playlist to the xmms - player.

TODO:

Configure the xmms - player to another soundcard or another channel of your soundcard.

Use the "Sent To" "Headphone" button.

That it is. The song will be played with the xmms - player.
