block size and behavior for the legacy agc is also another feature id like to see put into the current agc. RMS in current agc seem to have little to no effect versus the legacy block size

Whenever MB1 is ON, DeClipper input signal gets reduced by 12dB. Easy to check with "hear" in Declipper. Same as in ND but it rises signal when MB1 or AGC is ON. |

I don't see that here and I also can't explain how that could happen - can you send me a preset in which this happens?

Just one more question about the individual bands in the new AGC. In one of the past posts I had suggested extensive enhancements like a band mix, a better coupling etc.Will you still be looking at parts of it? I think that these suggestions are very useful, especially if the competition has them as well. From my personal point of view, they would make the whole thing even rounder. Addendum: I can just see that you have already implemented large parts of the requirements. Now I feel bad that I reminded you again of my former post. There are only little things missing. I am sorry |

My responses are inline: Quote: Instantaneous Dynamic Range, or ‘IDR’ is the main setting to adjust the amount of
Is that different from what the "RMS window" setting does? Or is the range bigger? In ST, both attack and release respond to this which may be different.control action you wish your Ariane Encore to have. The IDR setting is the ‘size’ of the RMS energy window in the windowing-release system. As long as the short-term variations of the RMS energy in the audio remain within this range, the Ariane Encore will stop making any changes to the gain in that band. Quote:
GATE AND RTZ
Can you explain how this differs from the existing gate? Is it looking at the output level instead of the input level, for example?The Gate threshold control determines the point below which the Ariane Encore will not seek to increase audio gain. Audio that falls above this threshold is considered valid, and fair game to be brought up toward operating level. The Gate adjustment can be set anywhere from a low of –35 dB below 0 dB nominal reference operating level, to as high as –15 dB below 0 dB, in one-dB steps. The higher the Gate threshold, the less any low level material will be boosted. In addition, there is a parameter called ‘RTZ time’. This stands for ‘return to zero’. When the audio energy in any band goes below and stays below the gate threshold for more than 10 seconds, the control circuitry slowly returns the gain of that band to zero. The time this takes is controlled by the RTZ Time parameter – the lower the number, the faster the return. This prevents the ‘rush-up’ of a quiet band, which could otherwise result in an increase in the level of unwanted background noise or intentionally very quiet programme material, such as that found in classical music, for example. RTZ sounds like it shouldn't do much, 10 seconds with no audio on specific bands is a LONG time. Maybe for classical music indeed. Quote: MIX
Easy to add (it's already there in the code, I just need to add parameters).The Mix controls for each band control the output levels after processing, in a range of +5 to –5 dB. These controls allow you to tailor your spectrum the way you like, or to compensate for another piece of equipment, if necessary. We normally recommend you keep these controls to ‘flat ‘ (0dB), and make your spectral manipulations elsewhere. Quote:
BAND TO BAND COUPLING
Makes sense. For the bass band we have this, but not (yet) for the highest band. Shouldn't be difficult to add. But, since you pasted the whole thing, are you missing something in the bass behavior?The flexibility of the Ariane Encore is enhanced by various coupling and restriction controls. The Low frequency band (B1) can be restricted from ever adding more gain than is userspecified, with respect to the dynamic gain of the Low Mid band (B2), using the preset|agc|xxx params|b21 coupling: (setting in dB) menu setting. Similarly, using the menu setting: preset|agc|xxx params|b34 coupling: (setting in dB) ...the high frequency band (B4) can be restricted from adding more gain than is userspecifed, with respect to the dynamic gain of the High Mid (B3) band. (b21 means ‘band 2 to 1’, and b34 means ‘band 3 to 4’. These parameters are duplicated within the ‘matrix params’, ‘stereo params’ and ‘dual mono params’ submenus – for clarity we’ve just put ‘xxx’ above). When enabled, the restriction controls make it impossible for the low and high bands to ever operate with more than a specified amount of gain beyond that of the adjacent band (note: they are always free to operate with less gain). Quote:
PROTECTION PEAK LIMITING
What exactly does this protect?The Ariane Encore has a built-in lookahead limiter before its output for protection purposes. Quote:
CROSSOVERS
That's there, just go to Advanced or Expert mode (not sure which one).
In the menu ‘preset|xover’, the crossover frequencies between bands 1/2, 2/3 and 3/4 can be adjusted. We think the default values are the best, but your mileage may vary! In addition, this menu includes a high-pass filter. Since in FM broadcasting, audio below 50Hz is largely unwanted and unheard, you may choose to enable the high pass filter to remove audio below this, or below a choice of other low frequencies. |

Ah lol I overlooked your last sentence. Anyway, please specify more clearly what you're missing |

I don't see that here and I also can't explain how that could happen - can you send me a preset in which this happens?

And yes, Window for agc is mostly fine qhen you have it on release only. I yold you to separate those two when you first time add it. Also other window settings confusing and should be way simpler. And also it does not work. |
