Upmix
The upmix feature of Anymix Pro is very useful if rearranging tracks with fewer input
channels into a specific surround format is not enough.
The upmix algorithm analyzes the incoming audio signal and separates it into parts of
direct sound and ambient sound. While the direct sound parts are sent to the direct
sound stream and can be placed at the virtual front speaker configuration, the ambient
sound parts can be modified and arranged around the virtual stage. Note that this
does not add any additional information to the audio stream. All sound parts that you
hear from the ambient sound were already part of the original audio material.
Switching to Upmix Mode
• To switch to upmix mode, activate the Enable option in the Upmix section to the
right of the stage view.
Ö The upmix algorithm is very sophisticated and can cause a high CPU load. Therefore,
you cannot automate the Enable option.
Stage View
In upmix mode, the parameters are represented by segments of a circle in the stage
view.
!
If your audio does not contain spatial information, there cannot be an ambient sound
stream. For example, you cannot extract ambient sound from a dry recording of a
narrator sitting in a recording booth.
!
Lossy compression, such as in MP3 files, or other deficiencies of the incoming audio
cannot be remedied using the upmix mode. For example, compression artifacts can
easily be misinterpreted and redistributed to the ambient sound stream.
