Wavosaur
What it is
Wavosaur is a free Windows sound editor for editing, processing, and recording audio files such as WAV and MP3. Its basic tools cover cut, copy, paste, trim, crop, delete, undo, and common processing operations. Batch processing can apply processes, effects, or VST effects to an entire folder. The program loads WAV, MP3, AIFF, OGG Vorbis, raw binary, AU/SND, and other formats, and exports MP3 through the LAME encoder. VST DLL support allows effect chains plus saving and recalling chains and presets. Recording features include ASIO, audio routing, multichannel audio, and input from a soundcard line-in or microphone. Analysis tools include RMS and channel statistics, two- and three-dimensional spectrum views, a sonogram, and a real-time oscilloscope. External MIDI controllers can trigger transport commands and volume control. Wavosaur runs directly as an executable without an installer or registry writing.

Who it suits
It suits Windows users editing, recording, mastering, looping samples, designing sounds, or mangling audio. Users wanting VST effects, batch folders, and analysis tools may find its feature set relevant.
