gEQ12 is a powerful 12-band stereo and mid/side graphic equalizer designed for precise audio shaping. It offers an extended frequency range from 10Hz to 48kHz, with 16 different filter types that blend analog and digital designs. Users can select from various filter slopes ranging from 6 to 96dB, and the equalizer supports independent processing for stereo, left, right, mid, and side channels on each band. The plugin operates in multiple modes including zero latency, minimum phase, and linear phase, ensuring flexibility for different mixing and mastering scenarios.

One of gEQ12's standout features is its high-resolution spectrum analyzer, which provides detailed visual feedback with 32k FFT processing. It offers multiple spectrum views including pre/post-EQ, max, average, live, and spectrogram displays, along with options for smoothed and raw data visualization. Users can load audio files as reference spectra and utilize tools like frequency tracking, spectrum freeze, and narrow-band sweeping to fine-tune their sound. The plugin also includes perceptual loudness matching and an extended meter section displaying Peak, RMS, EBU, and VU levels for comprehensive monitoring.

Designed for professional use, gEQ12 features sample rates up to 192 kHz and supports real oversampling up to 4x to maintain audio fidelity. Its zero-delay IIR filters and 64-bit internal processing ensure accurate and smooth parameter changes with full DAW automation support. The user interface is scalable up to 300%, accommodating different screen sizes and workflows. Despite its advanced capabilities, gEQ12 maintains efficient CPU usage, making it suitable for demanding production environments.
