time dependencies in compressors
Hi, It's me again, and I have another question about compressors :-) I'm trying to implement automatic gain control, including a noise gate, in a range of about 20 dB. So I used an RMS compressor bloc

SigmaStudio+ Sample rate propagation
I found out that the T-Connector would not propagate sample rate downstream. Remove the T-Connector and connect straight to the next block and the block's sample rate follows upstream. Does anyone hav

Compile numbers
I have a somewhat large program, and wanted to see if this complier message should cause any concern. The program compiled without error, and most specs on RAM and INST RAM seem comfortably under limi

Unconventional application of the ADAU1452 audio processor
I used an audio processor in a non-standard way for a metal detector. I want to be able to select a project (program) that will be loaded into the ADAU1452 from EEPROM by pressing buttons connected to

SigmaStudio move to 192KHz from 48KHz
I've been asked to reconfigure our dev board to 192KHz from 48KHz. So I decided to start with the eval board first. I asked AI for some help with this but it gave most of the registers different names

multiple units in the same circuit
Hey Folks, this may some crazy, but is there any reason I could not use multiple 1701's in the same project? I picked up a handful of the little "tinysine tsa1700" project boards, I'm wanting to make
