The API 2500 from Waves is a dynamics plug-in that features the classic punch of API hardware, while allowing for shaping the tone of mixes with absolute accuracy. Its dual channel design lets it function as two separate mono channels via a single compression setting.

Its auto-makeup gain function provides the ability to adjust threshold or ratio while automatically maintaining a constant output level. With a choice of an old style “feed back,” or the new style “feed forward” compression types, the software delivers a wide range of very musical parameters, making it a favorite of engineers everywhere.
