Cool Audio Editor

Cool Audio Editor enables you to perform various operations on audio tracks, as the name implies. It supports a few popular file types, such as MP3, OGG, WAV, WMA and CDA.
The tool is wrapped in a user-friendly GUI where you can import sound files using the default file browser. Unfortunately, it doesn't give you the possibility of capturing audio stream from an external source.
So, you can convert the sample type and channel mode, insert silence, mix the current file with another one, as well as cut, copy, paste or delete a selection.
Evidently, songs can be previewed in a built-in audio player. Several filters are applicable to these files, such as amplification, fade in and out, compressor, delay, flanger, normalization, phaser, resample, vibrato and stretch.
Furthermore, you can select another skin for the interface, as well as save the new audio track or just a particular selection to file, by specifying the output name, directory and format.
Cool Audio Editor runs on a low-to-moderate quantity of CPU and memory, so it shouldn't put a strain on the overall performance. It has a fair response time and generally works well. However, it has not been updated for a very long time, and we have come across some stability issues while testing Cool Audio Editor on newer OS platforms (such as crashing when browsing for a file).
