WaveShop is a free, open source, fast and lightweight audio editor for Windows. Unlike many similar apps, WaveShop is bit-perfect, meaning samples aren't altered unless they need to be. This is useful for patching a finished master without corrupting its dither. Waveshop's features include cut/paste, peak and RMS analysis, clip detection, normalizing, amplifying, fading, sample rate conversion, surround speaker assignment, audio generation, unlimited undo, and more.

WaveShop is a native Windows app, includes complete documentation, and supports most audio file formats. It's available with or without an installer (i.e. it can be a portable app), and in both 32-bit and 64-bit versions. Many additional features are currently in development, e.g. metadata editing, peak meters, spectral analysis, etc. If you would like to contribute to WaveShop, e.g. by coding, testing, documenting or translating, please contact me.
