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.

    Works like a charm from Day 1 on my Asus X750JN 17" laptop with RealTek Sonicmaster audio, running Windows 10 Pro x64 Technical Preview Build 10130. Functions 100% perfectly. The Peace GUI add-on also works great. Would be nice if this was updated to 64-bit, but I guess you can't have everything.

    hallo daar, ik draai windows 7 x64 met realtek high audio geluidskaart en ik heb een probleem, de EqualizerAPO64-0.9.2 sloopt de system effecten van de geluidskaart drivers, ik heb alles geprobeerd, eerst de EqualizerAPO64-0.9.2 installeren en daarna de laatste realtek drivers en tevens andersom maar krijg EqualizerAPO64-0.9.2 niet aan de praat. dat wil zeggen de EqualizerAPO64-0.9.2 werkt wel maar dan ben ik de systeem effecten kwijt, doe ik het andersom werken de system effecten wel maar niet de EqualizerAPO64-0.9.2, hebben jullie een oplossing voor dit probleem? mijn email is jwvdbosch@ziggo.nl bij voorbaat dank, nog 1 ding ik heb ook een x86 32 bit machine met windows vista waar EqualizerAPO64-0.9.2 gewoon correct werkt, maar wat raar is is als je naar de registry key van EqualizerAPO surft staan daar achter de child apo's de waarden !key en !value wat bij mijn windiws 7 x64 machine niet het geval is, wat is hier het verschil?

    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.

    Was exactly what I needed. Took away a lot of my headaches while switching from foobar and Audition. Now they sound the same and my whole system is tight. My sub is now smooth and my sides dont have a rising response. Thank you so much!
