Mixed-Phase Technology Dirac s mixed-phase filter technology provides the highest performance available. Based not only on an average response, the stationary frequency response correction looks at the variations between different measurement positions and carefully makes a correction whose level of detail depends on the frequency-dependent spatial variations. Magnitude Response Correction Dirac s patented methods offer just the right resolution. Dirac Live improves the precision and the clarity of the audio imaging. Localization and stereo hearing, in general, depend on the similarity between and the quality of the channel impulse responses. This impulse response is critical for multichannel and stereo perception. With the unique phase response correction and magnitude response optimization of Dirac Live, listening becomes effortless and brings you one significant step closer to reality.Ħ Technical Highlights of Dirac Live for Home Audio Dirac Live Calibration Tool Graphs Impulse Response Optimization Frequency Response Optimization Amplitudeħ True Impulse Response Optimization Dirac Live is unique to the marketplace in that it provides true working impulse response correction as measured over larger listening regions. A smooth frequency response and an aligned phase response make the sound more natural and prevent listening fatigue during prolonged listening sessions. Reduced Listening Fatigue Time-domain distortions, caused by diffraction, cross-overs, and early reflections, make it difficult for our brains to interpret the sound. Dirac Live is the solution to achieve this in any size listening space. Since stereo and multichannel 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 signal paths, only true mixed-phase impulse response correction can improve the spatial perception of a sound reproduction. A Restored Sound Stage Dirac Live restores the sound stage so that the localization of sound events become much more detailed. The result is a tighter, deeper and more defined low end. By adjusting the speaker outputs to the room modes, the character of the bass is restored to that intended on the recording.

Dirac Live effectively prepares the loudspeaker for the sound that is coming and reduces the settling time of the loudspeaker, thereby achieving a much tighter bass. Loudspeakers continue to ring even after a bass punch has been delivered due to mechanical restrictions. A Deeper and Tighter Bass Acoustic room modes distort the character of the bass. Voice intelligibility is improved and music becomes clearer. The result is 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 environment.Ĥ Benefits of Dirac Live for Home Audio Increased musical clarity and voice intelligibility A deeper and tighter bass A restored sound stage Reduced listening fatigueĥ Increased Musical Clarity and Voice Intelligibility 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 much more transparent and true-to-the-source sound can be delivered. 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 stationary frequency response. In addition to this unique technology, the RS20i also provides traditional tuning methods.

This true-to-the-source sound is obtained through the use of world leading room and loudspeaker optimization software from Dirac Research with practically unlimited resolution. By digitally optimizing the audio signal prior to sending the signal to the amplifiers and by measuring the output from each speaker of the audio system such that it is perfectly adjusted to the acoustical behavior of the listening environment, a much more transparent and true-to-thesource sound can be delivered. Rooms, amplifiers and loudspeakers inevitably distort the sound both in the frequency domain and in the time domain. However, how it will reach the listener is uncertain, due to the broad array of listening rooms, amplifiers and loudspeakers used. To understand the true benefits of this feature, let s start from the beginning: Sound is recorded according to the intentions of the artist and producer. Today, the technology is available to the high-end consumer audio market with the Datasat RS20i. 3 Dirac Research has worked for many years fine-tuning digital sound optimization and room correction.
