Multirate / hierarchy board and sampling rate error
Dear, I'm doing an audio DSP with filters, compressors etc. with SIgma Studio v4.6, on the ADAU1452. At first, I had a script entirely written on the main board, with multirate processing and it was w

UpSampling algorithm version 1.02 broken
I have just tried the latest version (1.02) of the Upsampling algorithm with SigmaStudio 4.6 and an ADAU1452. I am running at 96kHz sample rate and downsampling 16x, then Upsampling, with no filtering

Upsampling / Downsampling bug?
Hi, So I was trying to troubleshoot a project, and stripped it down to complete barebones to determine the issue. [Using an EVAL-ADAU1467Z Rev B board] Starting a completely new project & dragging in

ADAU 1452 Multirate instruction cycles and program overrun
I am investigating the Multirate features using Sigma Studio 4.4 and an ADAU1452 and I have some questions. I hava a project running at 48kHz, jam packed with processing. I have included a section usi

Downsampling/Upsampling blocks up to 64
Hello, I have a specific processing structure where I need to work at 750Hz (48k stream downsampled by 64). But because the downsampling/upsampling blocks are maximum 16, I do 2 downsampling/upsamplin

decimation with adau1701
What I'd like to accomplish is to clock the ADAU1701 on-chip ADC and DAC at a 96k rate and decimate/interpolate by a factor of 2 to run all the signal processing at a 48kHz rate. The goal is to use th

Decimation and Multi-Rate with Sigma Studio?
My SigmaStudio design includes a stereo decoder and then several other processes. The decoder has to run at least at 96kHz sample rate (best at 192kHz). The problem I'm running into is that I have to
