Description

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.

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
- modular graphical user interface

Requirements:
- 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.

    For Output Software Digital Signal Processing best Choice on Microsoft Windows. Room Bass equalizing is great with good measurement mic results. For Input... not really. Graphical Equalizer doesnt work. Microphone Sound crushes when Graphical Equalizer is in use.

    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.
