What are the number formats for SigmaDSP?

In the SigmaStudio help file, some of the algorithms have input and outputs specified as integer or decimal. Also, in the SigmaDSP datasheets, there are references to 28.0 and 5.23. Also, in SigmaStudio, sometimes cells will have other formats like 5.19. What does this mean?

  • I have used the dc input entry cell to set the threshold between two audio sources as shown below.

    106 is chosen to pass down to -98 dBFS. The value of "106" should be adjustable by the user in dBFS land. how can I map this integer value to dBFS? any equation to help?? basically the user should be able to change the threshold to higher in dBFS through our GUI but micro controller needs to know what integer should write to the DC cell.

    Thanks.
