For audiophiles and serious music lovers, sound isn’t just heard—it’s felt. However, the acoustics of your room can interfere with your equipment, no matter how expensive it is. That’s why Eversolo developed evotune, a next-generation calibration engine built to overcome these challenges.
Whether you’re optimizing a dedicated listening room, setting up a surround home theater, or simply want plug-and-play improvement for your stereo setup, evotune tailor your sound to your space.
What Does evotune Actually Do?
- Acoustic Scanning: This method records the whole acoustic fingerprint of your room using sweep and inverse sweep signals.
- Frequency Response Analysis: Creates detailed FR curves to show how sound behaves across a room.
- Intelligent Compensation: Produces FIR filters to rectify irregularities and enhance results
- Real-time calibration ensures consistent performance by dynamically adjusting to changes in the environment.
- Visual Tuning Interface: Calibration settings are straightforward to comprehend and adjust thanks to the graphical user interface.
Behind the simplicity of “tap to calibrate” lies a set of sophisticated algorithms and system architectures working together in real time. From precise signal capture to advanced frequency-domain modeling and intelligent filtering, evotune leverages deep engineering to deliver a highly accurate, audiophile-grade result.
Let’s take a closer look at the eight key technologies that power this innovation.

How Does it All Work?
1. Bidirectional Acoustic Scanning
evotune uses forward and inverse sweep signals to simulate how sound reflects and travels through your room. It precisely captures direct sound, early reflections, and reverberation—creating an accurate acoustic model.
2. Ultra-Fast Frequency Domain Analysis
Powered by an efficient FFT framework and parallel processing, evotune completes high-resolution frequency analysis in just seconds—ideal for setups requiring quick recalibration.
3. Precision Window Function Filtering
The system applies the Blackman windowing algorithm to reduce spectral leakage and side-lobe interference, preserving sonic smoothness and detail—especially in sensitive mid-to-high frequencies.
4. Automatic Acoustic Defect Detection & Compensation
Common room issues like standing waves and frequency dips are automatically detected and corrected using directional FIR filters.
5. Adaptive Curve Generation
Smooth correction curves are generated via multi-band interpolation and constraint-based optimization—avoiding the stepped artifacts typical of traditional EQ.
6. Visualized Frequency Response Interface
With its real-time graphical UI, evotune lets users see both raw and compensated curves, making adjustments precise and intuitive.
7. Independent Multi-Channel Modeling
Each speaker channel is measured and calibrated independently to maintain spatial layering and immersive imaging—perfect for multi-channel theaters and monitoring setups.
8. High-Fidelity Audio Architecture
evotune supports high-resolution formats and integrates seamlessly with DACs, amplifiers, and active speakers—ensuring every nuance of your source is preserved.

Experience Pure Sound
With evotune, you’re no longer guessing whether your room is holding back your audio system—you’ll see it, fix it, and hear the difference. It empowers all users to get the best possible performance from their equipment—without deep technical know-how.
Whether you’re fine-tuning your living room or pushing the limits of a reference-grade rig, evotune adapts to your space and preferences—giving you consistent, clear, and compelling sound, every time.
