TREQ is a classic four-band equalizer inspired by the iconic T-style design, offering precise control over your audio frequencies. It features switchable high and low shelves, allowing adjustment between 8kHz or 12kHz for the high shelf and 60Hz or 120Hz for the low shelf, both with a 15dB boost or cut range. Additionally, a high pass filter set at 50Hz is included to help clean up low-end rumble and maintain clarity in your mix.

The equalizer also provides sweepable midrange controls with a low mid band that can be adjusted from 100Hz to 1500Hz and a high mid band that sweeps from 1kHz to 15kHz, each offering up to 15dB of boost or cut. Input and output levels are adjustable within a ±15dB range, and a VU meter displays the output level for precise monitoring. These features enable detailed tonal shaping and dynamic control suitable for various mixing scenarios.

TREQ includes a resizable interface with touchscreen support, allowing users to adjust the window size between 50% and 200% via a simple handle in the bottom right corner. An oversampling mode can be engaged for enhanced audio fidelity, providing a cleaner, more accurate sound. This combination of intuitive controls and flexible design makes TREQ a reliable tool for achieving professional equalization results.
