Description

Equalizer APO is a 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.

    EQ works fine... BUT a BIG BUT, the installation messed up window scaling in games. During installation I had GTA V in 720p running fullscreen. It switched to fullscreen with black borders. So now the image is tiny and centered. The same problem still after windows restart. Before installing there was not any problems with fullscreen scaling from non native resolution. I have thinkpad, windows8.1 pro, i7, intel HD4000 and nVidia GT740m. This just got really annoying... What did the install change? it should not f*** up my screen setups. There doesn't seem to be option in the intel driver settings, there is only one oprtion and I can not change it, it's selected all the time ("Maintain display scaling"). Also there isn't an scaling option in the nVidia setting either. Why did this happen????

    I have a HP Pavillion 550-223 , with IDT sound card. This program locked everything up, rebooted with no sound. I had to uninstall the program and disable the audio driver in the control panel, and let it reboot, the first time it did not work, I tried it again, and it reinstalled the OEM sound driver(s). I saw the comment about only working with certain hardware, I had no idea what was in this computer, it was all OEM. It may work fine on different systems, just not this type of mass produced compute. I am sure the developer worked very hard on this and I am not taking anything away from them, it just doesn't work on this computer.

    Too esoteric - i.e., time consuming and non-responsive. Tried many configurations, and they did not work. Tried a previous posters GUI equalizer, and it did not work. The pre-amp did work. Hopefully it continues to develop and becomes more (user) intuitive. Also requires Java, which I do not like. Uninstalling (for now) and will try again later. Thanks.
