I'm just finally getting to trying the new beta Precedence and Breeze 2. I'm just getting my head around the links and multi instance editing - this is cool!!
My question is this:
What is this setting on Breeze 2.5?
I don't see a Breeze 2.5 manual, so I can't find it.
Thanks.
Here's the relevant info (and more) from the updated manual (which is not posted yet):
Distance Link DSP Mode
Overview
The Distance Link DSP mode is a special operation mode where the entire Breeze 2 algorithm is retuned to be optimized for and responsive to changes to the Distance parameter. The traditional Mix parameter is replaced with a Distance parameter and changes to it not only effect wet/dry balance, but also effectively cause the entire algorithm to update appropriately to augment the sense of distance and depth created by the algorithm.
In a real physical acoustic space if impulse responses are taken at different locations within the space, or the microphone position is kept static but the sound source changes position, the resulting impulse responses are never the same. Each position has its own unique impulse responses and embedded within these impulse responses are psychoacoustic cues that help establish distance, depth and positional cues. In traditional music mixing methods of using a shared reverb instance on sends, the impulse response is effectively identical for all instruments in the mix and the only variable is wet/dry mix as controlled by the gain values on each send that is feeding the shared reverb instance on the FX bus. This is rather crude approximation. It is improved quite significantly by using a tool such as Precedence on all track inserts, but even then, ideally many aspects of the reverb’s internal “secret sauce” should change and update in response to position information.
This is what the Distance Link DSP mode achieves. The simple act of changing the Distance Value will produce an infinite variety of impulse responses from Breeze; all with the proper “secret sauce” DSP changes that help establish depth in the mix depending on the Distance value. Moreover, we use “impulse response” here loosely; the entire process is actually algorithmic and variable with time due to modulation as would occur in the real world. Thus we have an infinite set of positions within the same general space, each of which is already an infinitely variable time-varying process!
Tip: Distance Link DSP Mode effectively creates an infinitely time-varying Algorithmic Multiple Impulse Response system.
Distance Link DSP Mode Additional Parameters
When using the Distance Link DSP Mode, a few additional expert parameters are available on the Main page of the GUI as well as on the “Big Time View” of the GUI:
• Mix Mode
• PD Adjust
• DR Adjust
• Angle
• P-Mode
Mix Mode
On the lower right of the Main Page of the GUI when in Link Mode, you will find a switch GUI element. This is the same functionality that is achieved by the clicking on the Mix/Balance label in the Standard Mode.
• Left Position = Mix Mode: In this mode no additional processing is applied to the direct sound. It remains dry, and is mixed unaltered with the wet output of the full Breeze engine.
• Right Position = Balance Mode: In this mode additional spatial processing is applied to the direct sound. The direct sound itself is also spatially enhanced, augmenting its sense of depth. This “enhanced direct energy” result is mixed with the wet output of the full Breeze engine.
Tip: The Balance Mode can be particularly effective with the Breeze Chamber Alg Modes on all source types including transient material such as drums. It can also work quite well on orchestral instruments with slower attacks such a string ensembles when using the Breeze Hall Alg Modes.
PD Adjust
Pre-Delay Adjust replaces the normal Pre-Delay parameter found on the Main Page of the GUI when using Link Mode. In the Standard Mode Pre-Delay is always simply set exactly the value the user specifies via the Pre-Delay parameter. In Link Mode, an appropriate Pre-Delay is set for the user according the current Distance and Size parameter values and a few other things. This takes the guesswork out the process automatically, simplifying the life the user.
PD Adjust is offered to appease preset designers, tweakers, and control freaks (we mean all of this as a compliment of course) to have additional control over the exact mapping of Distance to realized Pre-Delay.
• Positive values cause Pre-Delay to become larger faster with respect to increases in Distance.
• Negative values cause Pre-Delay to stay smaller longer with respect to increases in Distance.
As an example, if a particular preset has strong negative Contour values, and strong positive Shape values it will typically have quite a slow attack envelope. Such settings may benefit from having lower values of PD Adjust to keep the total time it takes to reach the peak of impulse response a little shorter.
DR Adjust
Direct Reflected Adjust provides advanced users and preset designs the ability modify exactly how the Distance parameter value changes the energy balance between Direct energy and Reflected energy. In simplistic terms this can be thought of as remapping a particular Distance value to a given wet/dry mix value. It should be noted that 50% Distance does not typically create the same result as 50% Mix. The Distance mapping is done in a manner that maximizes the useful range of the parameter, and achieves the most useful results possible when paired with Precedence. The default value is our starting recommendation, but DR Adjust allows this to be further customized to user taste:
• Positive values cause the signal to become “weter” faster, at smaller Distance values.
• Negative values cause the signal to stay “dryer” longer with respect to increases in Distance.
In real physical spaces changes to the Direct to Reflected Energy Ratio with respect to Distance would also depend on various properties of the enclosed acoustic space such as its size, geometry, and building materials; thus there is no exact universal formula that can be applied. As such we offer advanced users the ability to customize this behavior some as desired.
Note: In general, this is an advanced parameter that can normally be left as is found in presets.
Angle
Like Distance, Angle is also a parameter found in Precedence. It is provided with Breeze as well as a matter of convenience so that the value can be changed in either location depending on which GUI editor is currently being used. Angle does introduce some “secret sauce” changes within Breeze as well, though the more prominent effects come from a Linked instance of Precedence in this case.
Precedence Alg-Mode
Like Distance and Angle, Precedence Alg-Mode is also a parameter found in Precedence. It is provided on the Breeze GUI as well as a matter of convenience so that the value can be changed in either location depending on which GUI editor is currently being used. Precedence Alg Mode does introduce some “secret sauce” changes within Breeze as well. Each mode causes some variation to the resulting Breeze DSP algorithms, which are modified a bit to achieve the best possible paring with the current Precedence mode.
