Is it possible to implement a Wiener Filter and store noise estimated samples in SigmaStudio?

Hello Tamim,

SigmaDSPs are streaming/sample processors, the entire schematic will run every sample period. So, a new sample will come in and get processed and go out in that respective sample period. if your sample rate is 48KHz then the schematic runs 48K times with 48K new input samples. The samples can be delayed for some sample periods if you are using delay blocks or filters etc. But you really can't store any values inside the DSP, there are no buffers or memory available that let you store the values that can be used later.

s there a way to store these estimated noise values inside a buffer or place and then reference them in real-time as part of the processing equation?

You can route the filter's output to any other module for processing, but all modules (whole schematic) will be processed within that sample period. No matter how big your project is, an input sample will be processed thru all modules within that sample period.

So, storing some sample values and using it later is not possible.
