Introduction

The DaySequerra DownMix enables 5.1 surround sound to be transported through any stereo

infrastructure using the DTS Neural Audio process. Because DownMix renders sound independently of

the transport environment, it will compliment analog, digital, linear or compressed mediums. The

process is based upon the principle that both natural stereo and 5.1 content are two dimensional; both

contain width and depth spatial attributes. DownMix can represent six channels of discreet audio

sources into a stereo down mix by transforming the sources to pure intensity and coherence encoding.

By correcting overlaps of the signal sources in intensity, time, coherence, polarity, and phase before the

six channels are combined, DownMix accounts for the problems suffered in traditional matrix encode

systems (comb filtering, spatial location distortion, etc).

This proprietary DTS Neural Audio process, or "watermark process" guarantees that surround

information is faithfully reproduced when later rendered by the DaySequerra UpMix or any Lt/Rt

system. In brief, DownMix produces a stereo mix that accurately represents the original content

whether monitored in mono, stereo, matrix or DTS Neural 5.1 Surround Sound.

Operational Diagram

The diagram below shows a DownMix taking a multi-channel audio source and creating two-channel

audio using the proprietary DTS Neural Audio process of embedding a watermark signal within the

stereo audio signal patch containing spatial and steering positioning information. The resulting stereo

audio signal is also known as Lt/Rt.

This approach to down mixing the audio into a two channel signal ensures that it can be transmitted

through any stereo-capable distribution system. Since the audio output is watermarked, it may be re-up

mixed again into the original format.
