REAPER是一个多轨音频/MIDI音序器，但由于其便宜的价格，出色的性能，完整的功能，娇小的身材，立刻被广大平民音乐人所推崇。REAPTER是Rapid Environment for Audio Prototyping and Efficient Recording的缩写，也就是音频原型与高性能录音的快速环境。

据说REAPER的核心开发人员是从前Winamp公司跳槽出来的，可见水平还是很有保证的。

REAPER是一款工作站级别的专业音乐制作软件，包含多轨录音、音频混缩、MIDI编辑与母带处理等多项功能。软件采用64位音频引擎，支持目前流行的各类DX、VST音频插件与软音源，并自带多个品质出色的音频效果器。

正常运行REAPER，对计算机软硬件的要求很低。但是为了最大限度的发挥其功能，并提高工作效率，我们推荐采用如下配置：多核处理器，Windows 2000/XP/Vista，1G内存，至少1G的空闲磁盘空间，1280x1024显示分辨率，24位真彩色，支持ASIO音频驱动的专业音频卡或音频 接口。

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.
