Less Inst(cycles) in SS+ than in SS
My question is related to these two threads: - ez.analog.com/.../how-to-set-sample-rate-in-ss-like-done-in-4-7 - ez.analog.com/.../setting-sample-rate Preambule: I migrated a project from SSv4.7 to SS

LKFS Metering
I am looking into if it is possible to implement stereo LKFS Metering (or a close approximation of) in SigmaDSP. Here is the standard: https://www.itu.int/dms_pubrec/itu-r/rec/bs/R-REC-BS.1770-3-20120

ADAU1701 audio ADC DC offset
Hi ! We are using both audio ADCs of the adau1701. The DSP program is a simple mux allowing us to use either the analog or serial inputs of the DSP (see picture). We are using DIG0 and DIG1 to send bo

Different sample rates
Hi, When I use SigmaStudio, I am always confusing about different sample rates in hardware and software configuration. Could you please help me figure out them? Such as: 1. Software fs, 2. Hardware co

Set different FS for FastDSP and SigmaDSP when compile
Hi All, I use SigmaDSP of ADAU1787 to run algorithm and it works well. I set the FS is 48KHz in the toolbar. When I want to use FastDSP to run ANC and I need to set a higher FS(192KHz). I click link c

Noise reduction algorithm module for Fs=48kHz
Sigma DSP has noise reduction algorithm module for ADAU1761. Unfortunately, it runs only for Fs=16kHz. What’s need to be done to run it for Fs=48kHz. Thanks Mark Audio Signal Processors noise reductio

DC coupled input on ADAU1761
Hello there, is it possible to use a DC coupled input on the ADAU1761 in a single-ended input configuration? Specifically the line input pins LINP, LINNP, RINP, RINNP ? I'd like to be able to measure

ADAU1772 core_fs bits
Hi, I'm refering to ADAU1772 data sheet rev.C and SigmaStudio 3.11 to confirm the operation and noticed that if I creat project file, the core_fs bit is set as 96kHz. And I can't find a control to cha

Regarding developing a algorithm using sigma studio
I am developing a algorithm for FSK demodulation using ADAU1701 DSP IC without any hardware eval kit. In order to verify my design, I need to give a FSK input to the chip. Is that possible that we can

ADAU1772 : fs=44.1KHz
Hello, Can the ADAU1772 use the sampling frequency of 44.1KHz? Is it possible in the following settings? Integer mode: MCLK Input (MHz) = 11.2896MHz Input Divider (X) = 1 Integer (R) = 4 Fractional mo
