Listening Environment Optimizer™
Digital media content is everywhere today, from DVD, to IPTV, to the new generation of high definition players. This new digital content delivers beautiful video with incredible sound tracks.In the past the only place to experience this wonderful quality would be at the movie theater.
Today, consumers are adopting powerful home Audio systems that deliver theater quality sound at home. However, because audio quality is very sensitive to speaker placement and room size, many consumers are not able to get the best out of their systems. Setting up and configuring a home audio system can be a challenge.
The D2Audio LEO Listening Environment Optimizer running on Intersil's D2Audio family of Digital Audio Engines™ (DAE) helps to automate the setup and configure a home audio system. D2Audio's LEO is available exclusively through D2Audio and provides Automatic Room Mode Correction (ARMC) for the purest sound quality.
The Best Audio Listening Experience
Many experts suggest using a high-power sound system for the best home theater experience. High-power delivers the most accurate sound reproduction for the most realistic experience whether watching movies or listening to CDs. But with high-power, comes a new set of concerns. A high-power audio system is capable of "exciting" the room. When the room becomes excited, standing waves are established that increase the apparent sound in some locations, while decreasing it in others. Both effects and undermine audio enjoyment.
Theory of Operation
The D2Audio LEO sound processing uses a simple microphone to listen to the system’s sound at key positions in the room. D2Audio LEO generates several special audio signals that allow the internal DAE DSP to understand how the speakers sound within their environment. Once the D2Audio DSP has established the baseline sound characteristics, several specially selected frequencies will be tested. These frequencies have been selected to detect room mode effects.The D2Audio DSP is used a second time to calculate where the sound is too strong and where it is too weak. The DSP uses this information to generate a special correction for each situation. The DSP is used a third time to determine the best correction and the best way to implement that correction. Calculating the corrections is very involved mathematically. The correction is then stored in the amplifier delivering the best sound possible from that time forward.
Enjoying Digital Media
With the audio system custom tuned to the room, all that is left to do is sit back and enjoy the new sonic experience. The D2Audio LEO delivers beautiful room corrections for the purest sound quality to match the incredible video of today's home theater configurations. |
