Cockos has released beta preview versions of some of the plug-ins that are a part of REAPER, in Windows VST effect plug-in format.

The ReaPlugs:

• ReaGate: a configurable gate with wet/dry controls, look-ahead (on hosts that support PDC), hysteresis, hold, noise generator, MIDI event sending (on hosts that support it), built-in filtering sidechain as well as supporting sidechain inputs, and more.
• ReaComp: a compressor with a lot of controls (wet/dry/pre-comp/sidechain/knee). It also has a program dependent auto-release mode.
• ReaFir: a FFT-based EQ/dynamics processor/noise removal/analysis plug-in. ReaFir can do a lot of types of processing, from standard linear FIR-based EQ, to noise signature detection and removal to per-band compression and gating.

ReaPlugs can be downloaded directly here.
