What Wavosaur is

Wavosaur is a free Windows audio editor for recording, processing, and editing sound files, including WAV and MP3.

It loads formats such as WAV, MP3, AIFF, OGG Vorbis, raw binary, and AU/SND, and exports MP3 using the LAME encoder. VST DLL plugins can be loaded and arranged into effect chains, which can be saved and recalled with presets. For recording, it supports ASIO, routing, multichannel audio, and input from a soundcard line-in or microphone; output reaches 192 kHz at 24 bits. Analysis features include RMS and channel statistics, spectrum views, a sonogram, and a real-time oscilloscope. MIDI controllers can trigger transport and related commands.
