Wavosaur is a nice freeware audio editor, it proposes basic and advanced features for editing your audio files. You can cut, copy, paste, mix, trim, normalize, fade, remove mono material (”vocal remover”), remove DC offset etc. It imports wav, mp3, aiff, iff, and raw binary files.

Wavosaur support VST plugin effects, you can set a chain of effect in a virtual rack, and listen to the processed audio in real time.

Wavosaur can record your audio up to 192 KHz, it also implements batch processing: you can batch process an entire folder of audio files.

Loop creation is very fast and easy, loop points informations are saved for use in sampler softwares. This software will provide several tools for analysis, such as statistics, sonogram, 2D and 3D spectrum.

The software can be controlled with a MIDI control surface. The development is active, and donations are welcome.

Wavosaur Features:

• Multiple Document Interface for working with many files in one session
• All classic editing functions : cut, copy, paste, paste mix, paste replace/insert, paste to new file, trim/crop, delete, undo.
• Many processing options: mute, channel convert (stereo->mono, mono->stereo), insert silence, change volume, normalize level, fade in/out, invert/flip, undo.
• Accurate waveform representation, fast zoom in/out, clean easy to use interface Right mouse to scroll/display context menu. Skinable editor look.
• Resample, bit-depth convert (8,16,24,32 bits), pitch shift, vocal removal, DC offset removing, auto-trim, silence remover, interpolate, auto detect region, crossfade loop, exporting multiple wav file from regions.
• Wavosaur can import, save and edit loop points & markers informations in wav files. Snap to zero-crossing.
• Batch processing : apply process/effect/VST effects to an entire folder.
