Free equalizer software for linux

EQU is a realtime graphical equalizer that will equalize the audio of almost everything you play through XMMS (OGG, MP3, WAV, etc.).

You can choose four different band configurations (10, 15, 25 and 31), all of them with ISO central frequencies, independent gain settings for left and right channels, and more than +-14dB of gain per band.

EQU project features a skinnable GUI and shadowed mode.

3gp movie wizard is a small perl/kommander script that helps you to convert almost any movie format to 3gp movie, suitable for watching on the modern mobile phones (tested only on Motorola V360 but should work with any mobile with 3gp support and 176 pixel wide screen).

It should be extremely easy to use, yet offer advanced options such as a good subtitle support and video equalizer.

Fair DJ is an Mserv-compatible music server designed to play music in a room with several users sharing a set of speakers.

The users can rate songs, and Fair DJ selects songs using these ratings and a fairness algorithm to ensure that everybody is happy.

FairDJ is an extended version of Mserv, written in the Java programming language.

Installation:

Starting fairdj for the first time will create a settings file in your users home directory. FairDJ will print out a helpful location message specifying the path to this file. Since you most likely want to edit this file before starting Fair DJ for real, weve included a helpful install option which simply exits after creating the settings file.

Start FairDJ with the following command line:

java -jar fairdj.jar -install

FairDJ should exit after logging a message specifying where the settings file was written. To specify another location for this settings file, use the settings option:

java -jar fairdj.jar -settings < settings file >

Edit the settings file by hand, using your favourite XML/Text editor, to point to wherever you want to store your ratings, where your music is, and where your user database should be. The settings file is fairly well commented and should provide you with the information you need to configure your Fair DJ installation. The new user database will be empty, and only the default user and password, as specified in the settings file, will be valid.

To get help on the available options, use the help option:

java -jar fairdj.jar -help [< option >]

To connect to FairDJ, connect with a telnet client to the specified port (default 4444), for example:

telnet localhost 4444

Log in with your default user and password. To get help on the available commands in FairDJ, type "help" followed by enter in the telnet client.

Start by creating a superuser (master), and a user for yourself. They can be the same if you want to. Here is an example:

create myuser mypass MASTER

Known issues:
* Ogg tag support has not been verified.
* Equalizer has not been implemented.

delfin 20030216 is an excellent tool that was specially designed to be a realtime software sampler for Linux.

Have you ever gone out to find a hardware to create contemporary music (Hip-hop, Jungle, Techno, ...) with considerable price? Did you know that you can use your humble computer to do the same job?

And then a sampler needs lots of memory, so you got to spend more quids upgrading it. The sound quality of delfin and its actual interface doesn't come near that of a real harware sampler, but it might become a full-grown, all-mighty, powerful sea singer.

Instructions:

• In the delfin directory just type: install.sh
• This will move the delfin executable to any of your binary paths.

Enhancements: 16-02-2003

• It has grown a little bit in size, but it is much modular now.
• The on-line help will be a big surprise for all of you who didn't understand how to work with delfin.
• Added a test module, Discrete Fourier Transform, that can be used as equalizer.
  

Requirements:

• Linux with soundcard
• ncurses library
• gcc compiler

KXplayer is a very simple media player, based on xine. Its my hobby-project - just a way to get a better knowledge of KDEs internals.

Besides I wanted to learn programming C++ and since I believe the best way to learn programing is to write a program, I just made my mind to write a multimedia player.

Since it is a player, this word had to be in present in the title. The K and X appered there because of KDE (interface) and XINE (backend).

I took the decision to write a player because I needed one. I needed a good media player for KDE (something like XMMS with KDE inderface), which would be working as reliably as possible.

At present my PC is a 750MHz Duron with 128MB RAM and its almost imposible to work in OpenOffice.org and listen to MP3/OGG at the same time. Running XMMS and OpenOffice 1.x together on my Mandrake results in sound fragmentation.

For some time Ive been using boombox (you can find it in kde-apps). It is based on xine and I found it working better than xmms - almost no fragmentation. Unfortunately boomboxs interface is a bit strange (IMHO) and its not saving the equalizer settings (very annoying).

Nwfiir audio tools is a free suite of console programs for your Unix machine (Linux in particular) to process high resolution digital audio. The suites core program is nwfiir, which is a real-time digital equaliser. The name is a combination of the abbrevations FIR, IIR, WFIR and WIIR, that is four types of filters, Finite Impulse Response, Infinite Impulse Response and their warped counterparts. Currently only FIR and WFIR have been implemented in the application
The goal of room equalisation is to have a desired power response in the listening position. The desired response is most often the flat one, that is when all frequencies in the audible range, from 20 - 20000 Hz, are equally amplified. You may own very expensive speakers and amplifiers and so on, that will produce a flat power response, but only if it is placed in an anechoic lab environment. The room have a profound impact on the sound.
To minimise the problems, one can measure the power response in the listening position with a microphone, and with help of that put in a precisely tuned equaliser that minimises the rooms negative impact on the sound. Commercial systems exist for this (Roister, Tact Audio), however they are still very, very expensive. The software presented here is a a full room equalisation system, apart from the hardware which you may well own already anyway.
Enhancements:
- New component: fird, a FIR filter designer, however with no psycho-acoustic stuff yet.
- A quick hack: fconv, a fast convolver, ugly code lack of features and so on, but can be used to demonstrate how much faster fast convolution is than convolution in the time domain (which nwfiir does).
- Fixed some Makefile stuff.

SoundCard Plugin is an input plugin for XMMS which enables to read audio data directly from the soundcard.

Using the plugin you can now use your computer with the XMMS player as a powerful sound processor with any of XMMS effect plugins, such as, equalizer or echo effects.

In particular, this plugin in combination with the FIR filter plugin enables you to use your PC as a DSP to process audio data in real-time using long FIR filters without any need for dedicated DSP hardware.
