Person adjusting the volume on an AVR in a living room.

It is not tuning. It is correction.

If you think room correction is just EQ, you are only seeing half the problem. Dirac Live corrects how sound behaves in a room.

Why “just EQ” falls short

Equalisation changes level. It reshapes frequency balance by boosting and cutting bands. That can alter tonal character, but it does not address the timing errors rooms introduce.

In real rooms, reflections arrive milliseconds after the direct sound. Bass energy lingers. Phase relationships shift. These are time domain problems, not just tonal ones.

  • Smearing transients and masking voices

    Voices should be the easiest thing to hear. Yet in many rooms they feel buried, thin, sharp, or strangely distant. When you feel you need to turn up the volume you know the sound is off.

    In normal rooms, early reflections from walls, floors and ceilings arrive fractions of a second after the direct sound. These timing errors cause transient smearing and comb filtering, which blur detail and mask the frequency range where speech intelligibility lives.

    Dirac Live measures how sound actually arrives at the listening position and corrects both timing and tonal errors, restoring clarity, focus and natural presence to voices.

  • Distorting and exaggerating the bass

    Low frequencies feel inconsistent. Some notes dominate while others almost vanish. Bass energy lingers in the room, bleeding into midrange detail and reducing impact.

    Room dimensions create standing waves and modal resonances that exaggerate certain bass notes and cancel others. What you hear is not what your system is producing, but what your room is distorting.

    Dirac Live analyses how bass behaves in your space and corrects both level and decay problems, producing low end that goes deeper, hits cleaner and stops when it should.

  • Collapsing space and realism

    Instead of a defined soundstage, you hear a wall of sound. Instruments blur together. Depth is shallow. Everything seems to come from the speakers rather than existing in space.

    When frequency imbalance and timing misalignment dominate what reaches your ears, the micro timing cues that define localisation and depth are masked. The room flattens the sound before it ever has a chance to form.

    By correcting impulse response, phase behaviour and frequency balance, Dirac Live preserves spatial detail, restoring separation, depth and a stable three dimensional soundstage.

What room correction actually means

Dirac Live measures the full impulse response of your system in your room. That includes both magnitude and timing behaviour. It then applies mixed phase correction to address frequency response and time alignment together.

The goal is not to shape the sound to taste. It is to reduce room induced distortion so transients, decay and spatial cues behave more as intended.

-Corrects timing and frequency behaviour

-Models sound across a listening area, not a single point

-Targets audible perception, not just curves
