The Linux Soundfile Editor Roundup
KWave has been in development since 1999, so perhaps I should have included it along with the venerable stalwarts. However, its development team has kept pace with its intended target environment, KDE, thus giving KWave a more modern look and feel along with some interesting improvements.
The new KWave has also retained the original's emphasis on graphical tools for processing your files. Figure 15 shows off KWave's low-pass filter editor, complete with a processing preview function. The Listen button loop plays your file or selection while you adjust the filter in real time, a handy feature for testing effect parameters.
Some of my favorite tools, such as the additive synthesis generator, from the original KWave have not yet been reimplemented. Those tools currently are grayed-out in the menus, but the developers plan to restore those functions and add new features. Like GNUsound, KWave's file size is limited to available memory, but it otherwise is a fine editor and is well suited for casual use on the KDE desktop.
I hope this article has stimulated interest in checking out some of these applications. Believe it or not, other soundfile editors are available, though I have tried here to focus on the most popular ones. The Soundfile Editors section of the Linux Sound & MIDI Applications site has a full listing of the available Linux soundfile editors (see the on-line Resources section).
So which one is right for you? It's hard to say. I'm partial to Snd for its vast programmability and to ReZound for its GUI and organization, but you have to try some and see which fit your needs best. Above all, don't be intimidated by the apparent complexity of some of these editors. Approach them as you would The GIMP, testing their features at random until you have a sense of what they can do—don't be shy about clicking on the Undo button. Playing around with this kind of software can be fun and open some interesting creative avenues. And if you come up with some sounds to share, feel free to let me know about it. Now, go forth and edit those joyful noises.
