AutoCAD allows you to solve the most complex design problems. A wide variety of bodies and surfaces are modeled by means of creating arbitrary shapes; project verification time is significantly reduced; parametric drawings help you keep all the information you need close at hand. Design ideas can be visualized in PDF format, as well as implemented in layouts obtained through 3D printing. Never before have ideas turned into reality so quickly.

REAPER is a powerful but sensible Windows application that lets you record, arrange, edit, and render multi-track waveform audio. It provides an extensive set of features, but is a very small and lightweight application (the installer is less than 1 megabyte, and includes many effects and a sample project). REAPER supports ASIO, Kernel Streaming, WaveOut, and DirectSound for playback and recording. It reads WAV, OGG, and MP3 files, and records WAV files. You can arrange any number of items in any number of tracks and use audio processing plug-ins (DirectX and Jesusonic). REAPER also supports volume, pan controls and envelopes per track, multi-layer undo/redo, and user creatable color themes.
