Parametric equalizer. Lets you adjust specific frequencies using gain, bandwidth, and center frequency controls. Each band can be configured individually to correct sound problems or adapt to personal preferences.
Customizable filters. Includes options to apply high-pass, low-pass, band-pass, and notch filters. These filters modify the range of frequencies that pass through the audio system.
Phase correction. Adjusts the phase of audio signals to resolve time alignment problems between different speakers or drivers.
Dynamic compression. Reduces the dynamic range of the audio by compressing volume peaks and amplifying quieter parts.
Signal limiter. Prevents distortion by setting a maximum output level, useful for protecting sensitive audio equipment.
Tone generator. Creates test signals such as sine tones, white noise, or pink noise for calibrating sound systems.
Convolution. Applies impulse responses to simulate the acoustic characteristics of rooms or the effects of specific headphones.
Modulation. Includes effects such as vibrato, tremolo, and amplitude modulation to alter sound characteristics.
Delay and echo. Adds configurable delays to the audio, allowing you to create spatial effects or correct synchronization problems.
Channel mixing. Combines or redirects signals between different audio channels, useful for multichannel setups.
Real-time analysis. Displays spectrum graphs and signal levels to monitor changes in the processed audio.
VST compatibility. Supports plugins in VST format to expand functionality with additional effects.

Equalizer APO was originally developed by Jonas Thedering in 2011. The project is maintained as open-source software hosted on SourceForge. It is written mainly in C++ with specific components optimized for digital signal processing. Updates have added compatibility with newer versions of Windows and improvements in audio processing.
