Free sound editing tool software for linux

Easiest Edit In Place enables Web (2.0) developers to generate any number of edit in place widgets with only one line of script code.
Using stylesheets and spans, any piece of text can be edited by any type of widget. Easiest Edit In Place features CSS customization and automatic caret positioning.
Main features:
- It requires only 1 line of javascript to make any number of widgets editable.
- Caret positioning. When editing inline, the caret is positioned at the point the user clicked, to make it more intuitive.
- Editor can be anything, from ordinary text input to text areas or custom widgets.
- Everything can be styled using CSS.
Eeip has been tested on Firefox and IE.
Enhancements:
- A bug that could lead to the accidental display of placeholder text when dealing with empty fields in some circumstances was fixed.

Ice Sound Manager was designed to ease the management of sound events, sound themes, and the IceSound server in the IceWM environment under Linux/Unix. It is also intended to be an improvement upon the noble, but primitive icesndcfg.
The main improvements over icesndcfg include a support for sound event "themes", more comprehensive help, easy management and configuration of the IceSound server, a cleaner GUI interface, automatic starting of the IceSound server, and a more conservative approach to disk space usage. In addition, Ice Sound Manager includes a built-in "Setup" program which runs the first time you run Ice Sound Manager.
The application is written in Python (making it more easily ported across various platforms and architectures) and uses GTK through the PyGTK libraries. This application is available in both .tar.bz2, RPM, and static binary (for people without Python/PyGtk).
Please note that the tar.gz file does NOT need to be compiled (this is python, remember). System requirements are as follows: Python 2.2, PyGTK-2 1.9.9/2.0.0, IceWM (or IceWM-Gnome) 1.2.0 or better - with the IceSound Server executable (generally called, icesound or icesound-gnome). IceWM version 1.2.6 or better is highly recommended.
NONE of the following is required: Gnome, Gnome libs, or PyGnome (python-gnome). This application has NOT been tested with earlier versions of Python, IceWM, PyGTK, and IceSound Server. I cant say that it wont work with earlier versions, but I certainly cant say that it will. This application has NO dependencies on Gnome. 8-)

Ice Sound Manager has been designed and tested in the following environment(s): Mandrake 8.1, SuSe 8.1, Kernel 2.4.8 / 2.4.19, Glibc 2.2.4 / 2.2.5, XFree86 4.0.1 - 4.3.0, Python 2.2 - 2.2.1, PyGtk 0.6.9/PyGtk-2 2.0.0, Gtk version 1.2.8-4-1.2.10, Gtk+2 version 2.0.6, IceWM 1.0.9 - 1.2.15, IceWM-Gnome 1.0.9 / 1.2.2, with both icesound and icesound-gnome sound server executables. The test computers (3) were all Pentium 1, ranging in memory from 64MB to 256MB - nothing spectacular. It should run well on very old computers.
Requierments:
- Access to a Bash shell (very important), Python (2.2 or better), PyGtk-2 (1.9.9/2.0.0 or better), and Gtk+ 2.0.6 or better - neither Gnome nor PyGnome is required. (IceWMCP versions 2.5 and earlier require Gtk+1 and PyGtk-1 0.6.9) Repeat: IceWM requires NOTHING gnome-related.
- Also, your version of PyGtk should have the Gdk-Pixbuf modules on your system. Please run ALL IceWMCP programs from a BASH shell: Using other shells such as ksh, pdksh, csh, tcsh, etc. is likely to cause problems. If your IceWMCP programs have trouble launching other applications, it is most likely because you are using something other than a Bash (/bin/bash) shell. Run the programs from Bash...period! If you attempt to run the application and get ANY kind of error that says something like "Import Error", it means YOU do not have all the necessary Python libraries installed or do not have them installed correctly: This is NOT a bug, so do not file a bug report when you dont have the necessary software properly installed. Getting Python and PyGtk and getting them setup right is YOUR business. DO NOT ask for help installing Python, PyGtk, or GdkPixbuf. I recommend you get them from: http://speakeasy.rpmfind.net. If you are using a Python version lower than 2.2 and are too lazy to upgrade, use the "binary" distribution of IceWM Control Panel, or dont bother at all. NOTE: These requirements apply only to the standard pure-python version of IceWM Control Panel. Compiled, binary copies of IceWM Control Panel are stand-alone executables that do NOT require Python or PyGtk.
- Disk space requirements: The standard, pure-Python version of IceWM Control Panel uses approximately 1.75-2.2 MB of disk space - very small! The compiled, binary version of IceWM Control Panel uses about 3.7 MB of disk space. Yes, the binary version is large, so people too lazy or impatient to install Python and PyGtk properly and choose to use the stand-alone binary version will pay with disk space. At last check, the Hardware (or System) plug-in uses about 1.9 MB of disk space (most of it being the hardware ID data file).

SoundTouch Sound Processing Library is an open-source audio processing library for changing the Tempo, Pitch and Playback Rates of audio streams or files:
- Tempo (time-stretch): Changes the sound to play at faster or slower speed than original, without affecting the sound pitch.
- Pitch (key) : Changes the sound pitch or key, without affecting the sound tempo or speed.
- Playback Rate : Changes both the sound tempo and pitch, as if an LP disc was played at wrong RPM rate.
Main features:
- Easy-to-use implementation of time-stretch, pitch-shift and sample rate transposing routines.
- High-performance object-oriented C++ implementation.
- Full source codes available for both the SoundTouch library and the example application.
- Clear and easy-to-use programming interface via a single C++ class.
- Supported audio data format : 16Bit integer or 32bit floating point PCM mono/stereo
- Capable of real-time audio stream processing:
- input/output latency max. ~ 100 ms.
- Processing 44.1kHz/16bit stereo sound in realtime requires a 133 Mhz Intel Pentium processor or better.
- Platform-independent implementation: The SoundTouch library can be compiled for any processor and OS platform supporting GNU C compiler (gcc) or Visual Studio, for example Win32, Linux, AIX.
- Additional assembler-level and Intel-MMX instruction set optimizations for Intel x86 compatible processors (Win32 & Linux platforms), offering several times increase in the processing performance.
- Compiled executable binaries available for Windows.

Sound Mural is a picture-to-sound converter plugin for Xpaint.
An image that has been loaded or composed in Xpaint is treated as a spectrogram, and the corresponding audio is written out as a WAV file.
Examples of what Sound Mural can do, can be seen and heard on the Sound Mural Web page.
To use sound mural, you need an XPaint that supports loading precompiled filters. Future official versions of XPaint might support this, but until then you can download the source here.
The modification adds a "Load Precompiled Filter" menu item to the C_Script menu. It pops open a file selection box, and you select a .so file which contains a precompiled filter, which it loads.
After it is loaded, you can run the filter from the "User Defined Filter" in the "Filters" menu. Although this modification was made to XPaint to support Sound Mural, it might be generally useful.
Your X needs to be running in 24 bit color mode or better. Otherwise it will work but performance will be bad. It is probably a good idea to use a pure white background color in XPaint.
Non-white background colors result in constant background noise in the output of Sound Mural. And pure white pixels require no processing, so it goes much faster if most of the image is pure white.
Installation and use:
Type make to compile. You must have an XPaint that has the PRECOMPILED_FILTERS feature. If you have that, then you can load this module from
Selectors -> C_Script_Editor -> File -> Load_Precompiled_Filter
After it is loaded, you invoke Sound Mural by
Filters -> User_Defined_Filter
Each time you invoke sound mural, it will render the canvas as audio, and write a WAV file to the location specified in soundmural.c. The default location is /tmp/soundmural.wav.
Enhancements:
- Sound Mural is now a freestanding command line program.
- It reads a PNG on stdin and writes WAV on stdout.
