Equalizer APO is a parametric / graphic equalizer for Windows. It is implemented
as an Audio Processing Object (APO) for the system effect infrastructure
introduced with Windows Vista.
- virtually unlimited number of filters
- works on any number of channels
- very low latency, which makes it suited for interactive applications
- low CPU usage
- modular graphical user interface
- Windows Vista or later (currently only Windows 7, 8, 8.1 and 10 have been tested)
- Sound card driver must support APOs (this includes most onboard sound drivers)
- The application must not bypass the system effect infrastructure
(APIs like ASIO or WASAPI exclusive mode can not be used)
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.
If you want a hassle free graphic / parametric equalizer, then this IS the baby for you. I worked in the sound industry for many years, using some of the best equipment out there and I really do like the way this program has been made available for free! If you get stuck, there is a comprehensive online tutorial. What could be easier? Thanks to those that have given so much time into producing a great little product.
Was looking for a way to equalize my speakers with REW and came across this awesome project!
The program I so desperately needed, endlessly searched for and finally found!
Tried a combination of graphic eq [GraphicEQ: 25 0; 40 5; 63 5; 100 4.6; 160 2.2; 250 0; 400 -1.8; 630 -3.8; 1000 -2.6; 1600 0; 2500 1.8; 4000 4.6; 6300 7; 10000 7.8; 16000 7.4] ... and reduced my preamp to -4.80 dB ... works superb without any distortion at so fking high level of base (that's a cheap earphone came with my htc phone). Try it out. Wasnt' feeling so awesome with just the equalizer. Need to tryout. Windows 10 user. BTW, just created a Sourceforge account to write this.
