I'm interested in the DBMax and have a few questions about its Stereo Enhance function:
- Is the stereo enhance funktion is a dynamically controlled process so that a signal with a small amount of stereo perspective will be enhanced and a signal with an already excessive amount of stereo information will not?
- Does the Stereo Enhance work it in more than one band or in several bands independent from each other?
- Also I would like to know what it is the Stereo Enhance does exactly. Is it a kind of phase shifting or based on M/S decoding/encoding or something else?
It is not a dynamically controlled process as it does currently not measure the amount of stereo information present prior to processing.
Furthermore it cannot create pseudo-stereo from a signal with no stereo information; some stereo information has to be present for it to enhance.
The Stereo Enhance will process in two bands, as you have first the "Added Width" parameter, then an amount for the Low-band, and then a cut-off point between the Low-band and the rest of the signal.
It is based on M/S decoding, and specifically it minimises the amount of M (mono-information) in relation to S (stereo-information).
As most bass information will vanish when doing this, the Cut-off point was added.
