Linear Phase in an Audio System

A linear phase audio system is essential to ensure accurate, natural and coherent sound, eliminating temporal distortions that can compromise the listening experience.

What is linear phase?

A system has a linear phase response when all reproduced frequencies arrive at the listener without undergoing different delays between them. In a non-linear system, however, some frequencies may be reproduced with a delay compared to others, causing an alteration of the temporal integrity of the original signal. This results in a loss of detail, a less precise soundstage and a less natural sound.

Why is it important?

• Better temporal coherence : All sounds arrive at the ear at the same time, providing a faithful reproduction of the original recording.
• Greater soundstage precision : A linear phase response allows for the recreation of a more defined three-dimensional sound image, improving the perception of depth and spatiality.
• Less listening fatigue : The brain doesn't have to compensate for timing inconsistencies, reducing fatigue during extended listening sessions.

AudioLai and the concept of linear phase

AudioLai eliminates the issues associated with passive crossovers by using advanced DSP (Digital Signal Processing). This allows for digital phase correction, maintaining signal integrity and ensuring a linear phase response.

AudioLai: Philosophy and Implementation

AudioLai uses similar technologies as the professional industry, ensuring that their systems are optimized for uncompromising reproduction. Through the use of low distortion drivers and digital filters, they reduce phase aberrations typical of traditional crossovers.

Conclusion

The adoption of a linear phase design is not just a technical whim, but a design choice that significantly improves the listening experience. AudioLai demonstrates how careful phase management can make the difference between a good audio system and an extraordinary one.
