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.

    Fantastic work! I use it for an active pc crossover including room correction, works beautifully. I am looking into a way to implement Linkwitz-Riley crossover filters,should be possible with IIR.

    AMAZING... I use this with the Peace GUI: sourceforge.net/projects/peace-equalizer-apo-extension/ I have the Shure SE215 Earphones, I use Viper4Android on my phone for listening to music, and when I plug my earphones into my new MSI gaming laptop, I almost cried...until I found this! Here are my settings: Channel: all Preamp: -8 dB Filter 1: ON PK Fc 10 Hz Gain 14 dB Q 1.41 Filter 2: ON PK Fc 21 Hz Gain 14 dB Q 1.41 Filter 3: ON PK Fc 42 Hz Gain 10 dB Q 1.41 Filter 4: ON PK Fc 83 Hz Gain 5.5 dB Q 1.41 Filter 5: ON PK Fc 166 Hz Gain 3 dB Q 1.41 Filter 6: ON PK Fc 333 Hz Gain 1.5 dB Q 1.41 Filter 7: ON PK Fc 577 Hz Gain 2 dB Q 1.41 Filter 8: ON PK Fc 1000 Hz Gain 1 dB Q 1.41 Filter 9: ON PK Fc 2000 Hz Gain 2 dB Q 1.41 Filter 10: ON PK Fc 4000 Hz Gain 2.5 dB Q 1.41 Filter 11: ON PK Fc 8000 Hz Gain 4 dB Q 1.41 Filter 12: ON PK Fc 16000 Hz Gain 6 dB Q 1.41 Filter 13: ON PK Fc 20000 Hz Gain 6.5 dB Q 1.41 Hope that helps! So AMAZING. NOTE: Don't turn the Gains up too high or the sound will fade in and out. These settings give you incredible bass while retaining clear mids and crisp highs. Peace.

    This software is tremendous! It has a little bit of a learning curve if you use it without a gui, but put in a little time, it's worth it. As mentioned in the notes somewhere, it's best used with REW. Make sure you have a mic that has a calibration profile to get accurate response.

    Works great! I have a pair of Bluetooth headphones that have a less than ideal sound signature (too much midrange/midbass). This program helped me to correct it.

    I can't think of any program that can beat this. Excellent program, been using it for a week and I absolutely love it. Zero latency, does not mess with the audio quality at all. I would recommend using the add-on "Peace" to go along. Have my Røde Podcaster set up and it is so crisp and beautiful. If I may, it would be nice to have a threshold function, to remove background noice and only pick up the voice at a preferred level. Again, absolutely love this program, 5/5!
