Mostly due to Audio CDs, Microsoft’s proprietary audio format known as “WAVE” is still heavily used. It maybe a proprietary format and has its own limitations but it does have the ability to hold quality audio streams nonetheless.
But what if have one of those low quality Wav files (due to a bad recording device?) or what if it has higher audio levels that disrupts the output?, What can you do in those situations?
Well, most of the time you’ll never be able fix some of these issues (such as bad recordings) because the source file is ‘bad’ to begin with. But there are tools however with built in audio enhancing features that you try to enhance the quality of a “poor” Wave file.
If you use Ubuntu (or GNU/Linux in general) and looking for such app then Gnome Wave Cleaner is certainly one of the best!.
*. As said, this only supports Wav as the input format (play/pause functions of course).
*. You can re-encode the source file to Wav, MP3 and OGG Vorbis.
*. Supports splitting audio files (useful for large files).
*. Extremely user friendly UI (written in the GTK+ toolkit) with graphical Copy/Cut/Paste/Delete/Zoom-in/Zoom-Out editing functions.
*. Sonagram analyzer.
*. Add/Remove markers (so you can make changes only to selected areas).
*. Lot of built in audio related effects/enhancers such as: DSP Frequency filters, Amplify, De-noise, Sample, Silence, Pink noise generation, Declick related filters etc.
*. Manually change audio Denoise settings such as: Reduction, Amplify signal, Freq filters etc.
*. Change MP3 and OGG related encoding settings.
These are again few of its main features to mention.
You can install Gnome Wave Cleaner in Ubuntu 12.04, 11.10 Oneiric Ocelot, 11.04 Natty Narwhal, 10.10 and 10.04 by simply typing the below command in your Terminal window.
sudo apt-get install gwc
That’s it. Good luck.
