Equalizer APO - Free Parametric Equalizer for Windows

Equalizer APO is a free parametric equalizer for Windows. It is implemented as an Audio Processing Object (APO) for the system effect infrastructure introduced with Windows Vista.

Features:
- virtually unlimited number of filters
- works on any number of channels
- very low latency, which makes it suited for interactive applications
- low CPU usage

Requirements:
- Windows Vista or later (currently only Windows 7, 8 and 8.1 have been tested)
- Sound card driver must support APOs (this includes most onboard sound drivers)
- The application must not bypass the system effect infrastructure (possible by using special APIs like ASIO)

Equalizer APO is best used in conjunction with Room EQ Wizard http://www.hometheatershack.com/roomeq/, because it can read its filter text file format.

Please have a look at the Wiki http://sourceforge.net/p/equalizerapo/wiki/ for instructions on installation and configuration.
