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

Audio Delay versus Sample Rate
When operating the ADAU 1701 with double to fourfold sample rate the audio delay (analoge input to analog output) is not 1/2 or 1/4 compared to 48 kSps as expected. I measure 1/3 and 1/9 compared to 4

ADAU145x datasheet ASRC group delay calculation
On page 81 of Rev.D of the ADAU145c datasheet there are calculations for the ASRC group delay : The same equations appear in the AD1895 datasheet, so surely they must be correct. In the first equation

ADAU1452 sampling frequency
Hi, I use an ADAU1452 to EQ a few subwoofers, and noticed the filters were not working properly (ie. PEQ was not affecting the signal in any way!) I realized I was setting the sample rate only in samp

ADAU1452 - Working at fixed sample rate
Hi, I'm using custom ADAU1452 board only for S/PDIF audio processing. In SigmaStudio, "START PULSE" is set to "S/PDIF receiver rate". ASRC0 output rate is set to "Use DSP core START_PULSE rate". For t

1787: Choosing 768 kHz in SS results in compile error.
I am trying to change the sample rate so the FDSP runs at 768 kHz. I have changed the DAC_FS and ADC01_FS registers to 768 kHz, however when I change this setting in SS and 'link-compile-download', I
