ADAU1452 at 96kHz into ADAU1787 at 768kHz via I2S
Hi All, I am working on a project where I need to run a ADAU1452 with external ADC's and DAC's at 96kHz samplerate. The ADAU1787 get its signal from the ADAU1452 via I2S at 96kHz samplerate interpolat

ADAU1701 Eval board development related.
Hi, After multiple failed attempts, I was finally able to successfully build ADAU1701 eval board. However while I was building the existing circuit I struggled a lot with VDRIVE and 1.8 voltage on pin

1787 at 768 kHz?
Hello: I set up a 1787 eval board SDSP and FDSP to work together at 48 kHz and found I could pass audio through it successfully. I then tried to set up the same board with another project (attached) t

How to set EVAL-ADAU1466Z EVAL BOARD sample rate to 192Khz?
I have modified EVAL-ADAU1466Z EVAL BOARD to control AD1938 via Sigma Studio Version 4.6. and set sample rate to 96Khz and got sinewave(40000Kz) succcesfully. When I had changed to 192Khz it did not w

Distortion using sample rate fs 44.1k
I must have missed something very basic about dsp configuration. Here is my problem: I have set up my eval1467 board as an i2s slave (both bclk and lrclk) on in0. SigmaStudio schematic sample rate is

ADAU1452 with 2 x AD1938 at 192kHz
We have a product currently operating with ADAU1452 as master with 2 x AD1938 codecs at 96kHz, with DACS operating at TDM8. SDATA_OUT0 goes to AD1938 #1 and SDATA_OUT1 goes to AD1938 #2. It is my unde

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

Bug in sigma studio with adau1401/1701 running on 96khz?!
Hi, While making a sigmastudio file on a ADAU1401 system with external ADC and DAC, with the DSP as Master I found a very strange phenomenon. Included are 2 screenshot showing my design with the sigma

ADAU1446 I2S sample rate
Hi! We have a custom board with a ADAU1446 SigmaDSP and a AD1939 CODEC, both running with a master clock of 12,288MHz and sample rate of 48kHz. We would like to connect a Bluetooth board/chip over I2S

Is there Noise reduction function supported 44.1kHz and monoral sound?
Hello, One customer need a reduction function block on ADAU1761. In the customer application, some certain audio stream have like a white noise after ADAU1761. They try to remove this noise using Nois

96khz with EVAL-ADAU1442
Hi I just started using the EVAL-ADAU1442EBZ, could get audio through (analog in / analog out) as well as use the S/P-DIF in-out (including ASRC), but only with 48kHz - if I change the sample rate to

LP Filters above 22kHz
I am wanting to do a 'high' frequency Low Pass filtering while in 192 kHz sample rate mode but the filters limit me to 22kHz. Is there a way to do a low pass with cut-off values such as 30 or 40 kHz?
