Until recently, I thought that the only free non-bloated audio editor available for Windows users was Audacity. But that was when I did not know about Wavosaur which is a feature rich audio editor for Windows that can edit many different audio file formats like OGG, MP3, WAV, and even the RAW binary files. And unlike many other audio editor programs that do not even provide as many feature, the Wavosaur is extremely small in file size – the downloaded file is only 303 Kb total. It is so baffling that such a small program can come with so many features to edit so many different audio file formats.
In the Wavosaur audio editor, you can open multiple documents in the same window which allows for each copy/pasting of audio sections from one audio file into another. It features all the standard audio editing functions like cut, copy, paste, paste mix, paste replace/insert, paste to new file, trim/crop, delete, undo. In addition, there are so many processing options like mute, channel convert (stereo to mono and mono to stereo), insert silence, change volume, normalize level, fade in/out, invert/flip, undo.
Wavosaur supports VST (virtual studio technology) plugins using which you can extend the functionality of this software even further. You can download these VST plugins from the internet as there are so many websites that offer them. You can use more than one plugins at the same time in a chain to produce the desired effects.
ASIO (Audio Stream Input/Output) is also supported by Wavosaur which allows for direct recording of audio streams taken from various other inputs (such a microphone, line in etc) as well as audio routing to other devices. This way you can record the output from your guitar output very easily and process it through VST plugins at the same time before saving it into a file.
Conclusion: Wavosaur is a small but very powerful, feature rich audio editor. It supports all the popular audio formats, provides many editing and processing features, supports ASIO drivers as well as the VST plugins.
