EVOTUNE

evotune PRO is an acoustic correction system developed by Eversolo for high-fidelity setups. A USB measurement microphone records the real response of the room at the main listening position, and an FIR-based engine analyzes frequency and impulse response over a wide bandwidth, then turns the result into a correction profile. Up to three measurements are aligned and averaged, and the left and right channels are measured one after the other so that room asymmetry can be handled separately.

Correction can be delivered as a high-precision FIR filter or as a 20-band PEQ. Gain limiting and low-frequency protection stop the system from trying to fill deep nulls that cannot be corrected, which lowers the risk of clipping and overcorrection. The correction range can be limited to low and lower-mid frequencies or extended to a full-range expert mode covering 20 Hz-20 kHz. Several established target curves are supported, along with preferences such as tighter bass or warmer vocals, and professional microphone correction files can be loaded.

Operation is through the Room Correction app, which walks the user through a five-step workflow. A graphical display shows measured data, the target response and the predicted result together, with before-and-after curves.
