[Sigmastudio] Synthesis and analysis windows only accept 128 values
My project currently uses the trial version of the Acoustic Echo Cancellation algorithm, and the implementation is based off the example project provided in the Analog Devices wiki (https://wiki.analog.com/resources/tools-software/sigmastudio/toolbox/adialgorithms/aec).
It seemed to work fine initially, but at some point the synthesis and analysis windows around the RES block began to truncate the coefficient tables to 128 values, instead of 256. I'll load the 256 coefficients from a text file, the table will show the 256 coefficients, but when I close the table and reopen it, it will only show the first 128 values. This seems to lower the quality of the audio output.
Is there a way to adjust the table size for these windows?
I had the same problem some month ago. I had to increase the "SetBolckSize" (via right mouse click) of the Blockinputs from 64 to 128 to have 256 coefficients at the analysis windows. Hope this helps.
