But, I found, you still need a delay to reduce gain riding (read Dolby's doc's), and it also adds a simple reverb (space) effect.Ĭode: desc: 10-to-2 Channel Surround Sound Encoder The resulting signal will sound identical to the original, but will have a different wave form, which makes it possible for Dolby to separate the channels. Basically, a 90deg phase shift creates a 'clone' of your signal.

One last note: If you do want to use a phase adjust, simply use Utility/Phase_adjust or BetaBugs PhaseBug to apply a 90deg shift to the channels you want. You can use ReaSurround to create 5.1, 7.1 or 9.1 mixes if you wish. I also mixed in stereo, and used plugins to create a 10 channel mix to encode. Just a low pass filter to extract a LFE channel, and a eq for the final output. NOTE: There are no compressors, limiters or reverbs. Ive uploaded some screen shots of the settings I used for the demo mix. Ive been using +/-65deg (approx) as side left and side right. I found this to sound better than phase adjustments which can make the high end harsh, and isn't great for real time mixing.īasically this is a 10 tap delay, where each delay can be rotated.ĭolby defines +/-75deg (approx) as rear left and rear right. It uses delays and not phase adjustments to minimize gain loading. Its a 10-to-2 channel surround sound encoder. Spl1 = FR + RL * db2 + RR * db1 // Right Total Spl0 = FL - RL * db1 - RR * db2 // Left Total

** Note: The phase adjust was taken from 'JS: Utility/phase_adjust'.

** I have tested this encoder on a Kenwood Surround Receiver (KRF-V5560D) which has a licensed ** will take 4 channels (1-4) and output a stereo DPL/DPLII mix.

** To use, place this effect after a ReaSurround (set to quadrophonic). Evans Desc: Encodes a quadrophonic (4 channel) mix to a DPL/DPLII style stereo signal.
