A multichannel 31 sliders equalizer is possible with Peace.

Features:

• immediate response when you move a slider or apply an effect
• up to 31 gain dB sliders per channel/speaker, so acting like a professional equalizer (and more unlimited sliders by adding channels)
• 5 default equalizer configurations, setups as base to start equalizing (5 band, octave frequencies, 1/3 octave frequencies 31 sliders)
• several other configurations like dance, rock, bass boost for you to use
• 9 speakers support, equalizing all speakers at the same time, per speaker or combination (but unlimited speakers/channels if needed)
• per slider the filter frequency, dB gain, filter quality can be set/changed (depending on the chosen filter)
• filters: peak (default), low/high pass, low/high shelf, band pass, notch (band elimination), all pass (phase shifting) and others like Linkwitz-Riley and Buttersworth
• pre amplifying dB values for volume control per channel/speaker and overall
• graph of your filters (transfer function) per speaker/speaker combination
• make, save and use your own equalizer/effects configuration (preset)
• attach a hotkey to your configuration to activate it quickly within other software (a game for example)
• activating a saved setting by 1 click, attached hotkey, through Windows system tray or desktop shortcut
• 2 or more configurations active by putting them in the "Always active" list on the Automation window (shortcut: right click on your configuration in the list)
• minimize to tray: from the tray menu, select a configuration through tray, mute audio, change main pre amplifying, etc.
• your can choose a specific device to equalize
• apply effects such as balancing, up/downmixing, crossfeeding, bass and treble, channel routing
• play around by expanding, compressing, shifting the sliders through buttons
• audio can be muted by clicking or hotkey if you set it up
• the equalizer can be switched on and off for testing the difference
• headphones and hearing test interface for creating equalizations based on your headphones and personal hearing
• headphones EQ support from AutoEQ and OPRA
• automation: you can let Peace automatically activate a configuration (equalization, etc.) when a program starts or a device is selected
• still enter Equalizer APO commands in a separate window with support like examples and testing
• through the settings window you can change the behavior and look
• language support: English, Čeština, 简体中文, 繁體中文, Deutsch, Español, Français, 한국어, Nederlands, Italiano, Pусский, Türkçe, Українська (I'm looking for volunteers to translate to these and other languages)
• support for themes

As said besides all of this you can entered your own Equalizer APO commands in the Commands window, which can be executed before and after the Peace commands. In the commands window you can test the entered commands. The commands are saved with your equalizer configuration.

If you feel up to it you can make your own language file and if you send it to me I'll add it to the languages.

Notes

• Pre amplifying mute settings in Peace isn't the same as the mute of the Windows volume slider. Instead use the mute setting beneath the Peak level meter.
• A high pre amplifying can cause audio serious clipping and thus distortion.
• Peace configurations are stored in the config folder. A different folder can be set in the settings.
• Your configurations are automatically backed up in your documents folder.
• Some limitions on multichannel low frequencies usage as explained by Jonas Thedering in his wiki.
• Equalizer APO has a limit of 22050 Hz. Current Peace versions don't allow higher frequencies although you can set otherwise.
• Don't use Equalizer APO version 0.9, but use 0.9.1 or higher. Or 0.8.1.
