Dirac Live
Advanced Room Correction
Dirac Live® is a state-of-the-art digital room correction
technology which optimizes the sound both in terms of the impulse
response as well as the magnitude frequency response. The result is
a substantially improved musical staging, clarity, voice
intelligibility, and a deeper and tighter bass, not just in a small
sweet spot but in the entire listening volume.
Dirac Live® puts you - the listener- into where the music
actually happens. By digitally optimizing the output from each
speaker of the audio system such that it is perfectly adjusted to
the acoustical behavior of the listening environment, a totally
transparent and true sound can be delivered.
Dirac Live® analyzes the space in which it works - your audio
system and your room - and determines the proper timing and
amplitude of each part of the performance so that the purest
possible signal reaches your ears.
Emotionally, Dirac Live® allows you to be involved with the
music, not just to "listen" to it or be bombarded by it. The goal
of Dirac Live® is that music reaches you completely uncolored by
acoustic limitations.
- You are face to face with the recorded artists
- Your music is staged perfectly
- Your music reaches you as the artists intended when they made
the recording
- Your Dirac Live® digital acoustic tuning assures the purest
possible reproduction
Technically, Dirac Live® improves on other digital room
correction systems - as customer benchmarks show - by not just
making minimum-phase or linear-phase adjustments to the frequency
response. Dirac Live® is unique in offering true mixed-phase
impulse response correction. This is achieved not just in a small
listening region, but in a volume of arbitrary size. Several
measurement positions and separate time and frequency-domain
criteria are used to make sure all of the common pitfalls
(over-compensation, under-compensation, pre-ringings,
decorrelation, etc.) in advanced room correction are avoided.
Variable frequency and time resolution is used to correct not
just for an average response smoothed with some standard
resolution. Instead, the degree of detail in the correction is
determined from the amount of spatial variations both in the time
domain and the frequency domain. This gives a perfectly balanced
correction that adjusts to the size of the sweetspot and brings out
the full potential of your listening room and audio equipment. The
optimal target frequency response may not always be flat. Instead,
the Dirac Live® software suggests an adjustable target based on the
actual system measurements.
Dirac Live® sharpens the sound image, improves clarity and
tightens up the bass. Since stereo perception depends crucially on
the similarity, or correlation, between the signals at the left and
right ears, which in turn is determined by the impulse responses of
the left and right signal paths, only true mixed-phase impulse
response correction can improve the spatial perception of a sound
reproduction.
Without Dirac Live® you fail to obtain an accurate stereo image
and loose bass tightness. Overall clarity is lost and you are
listening to a sound system instead of a musical performance. Our
goal is to make you forget the sound system. Dirac Live® lets the
artists perform truly to their intentions.
