I'd like to know the specification of each blocks in the SigmaStudio4.2 toolbox.
1. There are 2 Volume Control blocks as below. Please let me know clearly the difference between these specifications.
Volume Controls -> Adjustable Gain -> Clickless SW Slew -> RC Optimized
Volume Controls -> Adjustable Gain -> Clickless SW Slew -> RC Accurate
2. There is "Adjustable Gain -> Clickless HW Slew" block in the Tree ToolBox.
How do I change Tr / Tf ?
3. There is an item of "Adjustable Volume Control" when I look at the help of the SigmaStudio4.2, but that block does not exist in the Tree Toolbox of the actual tool.
Is this an item that does not already exist?
Thanks and Regards,
The short answer is the RC Accurate is an accurate RC curve but it takes more MIPS to do it. The Optimized version is more of an approximation of an RC curve and uses less MIPS.

I think you are asking for Rise time and fall time?
We had answered all of these questions in great detail about two years ago for another customer that your company supports. Do you have that information available? I will look back at some of my documentation, I think I still have it. This would have to be shared directly and not via the forum since it was in great detail.

Sorry, Can you show me which page of the help file you are talking about? I am not certain so I do not want to answer your question incorrectly.
Thank you very much.
1 and 2 have been solved.
Item 3 is present in the help window as shown below.
This module does not exist in the toolbox of SigmaStudio4.2.I guess this module is integrated into "clickless HW Slew" of "Adjustable Gain" in "VolumeControl".
Is my recognition correct?
This description in the help file is a little old. I think this cell has been gone for a while. This functionality is still there for the hardware slew but it is not in a pull down box. I need to get a different screen capture program because I cannot capture pop up menus. So sorry I do not have a screenshot.
If you mouse over the lower part of the volume control GUI. Then right click and a menu will pop up. In this menu is a sub-menu called "Slew Type". Here is where you can set the slew type for the hardware slew. But I am not certain if you can change the slew time without writing directly to the memory.
Thank you always.
Please let me know one more thing.
There is "DC Blocking" module in the Filter toolbox.
Please tell me the detailed specification of this filter.
R = 0.9999 which is a cutoff of 0.1 Hz. at 48kHz fs. It does not change when the sampling rate is changed.
