Qt Based Audio Editor for Kubuntu (KDE) Users – KWave

As an Ubuntu user, if you’re looking for an awesome Wave file editor written GTK+ toolkit that integrates with the Unity desktop, then you should try GWC.

But if you’re a KDE geek 😉 who use Kubuntu then the Qt written KWave is also a decent alternative. It’s intended for the Qt/KDE desktop but thanks to compatibility between GTK+/Qt toolkits it works decently well under Unity desktop too.

Main features …

*. Comes with a simple and a clean looking user interface.


*. Multiple track editing.

*. Save edited Wave files in OGG Vorbis, Oga, Spx, Wave, Aiff, Aif, Flac etc. But due to patent issues, Kwave won’t let you save in MP3 format (export). But you can however import and edit MP3 file nonetheless.

*. A standard GUI editing window with Copy, Cut/Delete, Paste, Zoom in/out, loop playback, go to position functions (and more).

*. Built in plugins that add audio effects such as: Normalize, Amplify, Lowpass filters, Silence, Noise, PitchShift, Notch filter, Reverse playback etc.


*. Built in audio tag editor.

*. Sonagram filter.

*. Change the reserved memory on RAM, Virtual memory and memory reserved for Undo/Redo operations.

*. Live Record mode.

*. Change output audio device and codec settings are some of its features to mention.


Although Kwave developers say that you can import MP3/MP2 file after installing the “libmad” and “id3lib” yet even after installing them in Ubuntu, KWave wasn’t able to load MP3 while I was testing.

Anyhow before installing KWave, try installing those dependencies first, so hopefully it’ll work for you. For that please use the below two commands.

sudo apt-get install libmad0

sudo apt-get install libid3tag0

And then you can install Kwave in Ubuntu/Kubuntu 12.04 Precise Pangolin, 11.10 Oneiric Ocelot, 11.04 Natty Narwhal, 10.10 and 10.04 by using the below command in your Terminal window.

sudo apt-get install kwave

This is a KDE application and uses the never Phonon multimedia framework, and I don’t know whether if it’s because of that, but it crashed few times while I was using it and had few troubles with my audio output as well.

Although I think if you use Kubuntu or KDE as your main desktop most of those incompatibilities should go away (hopefully). But nonetheless, if you’re going to give a try at KWave, then please remember it has few issues.

Other than that KWave is a simple audio editor with decent amount of features. But if you’re not happy with it, then I’d humbly suggest Audacity. Good luck.
