Packing 8 16bit channels into one serial port
Hello! I'm designing V2 of my digital mixer, which uses an ADAU1466, ADCs, DACs, and an ESP32-S3 for the web interface. So far so good. V1 is working great, but for V2 I'd like to add multitrack recor

Understanding of gain stage, dsp headroom and serial port bit rates
Hello Ez, I am trying to properly understand the relation between gain stage, DSP headroom and serial port bit rates as the title says. The DSP is used as an active XO for stereo systems. It could be

Shift incoming I2S data left 7 bits
For reasons that are too long to explain here, the I2S data is arriving (logically) shifted right 7 bits. This is fine because it's really just 16 bits of valid data. Before I can use the data I need

ADAU1701 IIS input 192Khz signal to enable filter, DAC playback has noise
Specific operation description: As shown in the schematic diagram above, currently only one General 2nd filter is added, set to hpf and 60Hz corner frequency. Set the sample rate to 192K and the DSP c

How to increase Delay time?
Hello Forum Users, Delay time is often at a premium and being able to use it more efficiently is a good thing. The question is how do I more efficiently use delay memory? The memory is 32 bits but 32b

Calculating ADAU1701 coefficients in uP for long double vs float (64bit vs 32bit.)
The question first: Given that the actual coefficients in the ADAU1701 are only really 28 bits (the first nibble of the first byte is always a zero) how important is it that I calculate coefficients u

ADAU1452 and 32bit Word Samples with Filters, Delay, and Volume Control - Confirmation
Hi, If possible, can someone confirm whether the following is possible with the ADAU1452 and Sigma Studio 16bit/44.1kHz, or 24bit/48kHz I2S signal is input on one of the ports directly to the ASRC, co

adau144x TDM8 on scope
Hi , I am new to working with TDM8 24bits I have adau144x working in master mode The DSP is working in pulse mode in TDM8 24bit mode. I have delayed by one set ( i2s mode ) So I calculate there should

Split one 32bit channel into two?
I've an idea and I'm looking for some quick feedback on how feasible it is on SigmaDSP. I would like to feed a 32 bit signal into an input port. The deceptive part of this is that this "channel" would

Normalizing dynamic range of 12 bit AUX input to match 24bit codec audio
Hello Dave - or other SigmaStudio oracles My design is built around an ADAU1452 with two AD1938 codecs for audio I/O. This part of my design works fine. I've also routed two of the AUX ports on the AD

32 Bit Audio with ADAU1442
Hi there, I have a modular system with an ADAU1442 as signal processor. I would like to use an ADC and a DAC with a bit depth of 32 Bit. I know that the processor con process 24-, 20- and 16 Bit Data,

USBi Required for 64 bit ADAU1702 EVAL?
Hello, I'm using the 1702 based EVAL board and I am having trouble communicating with the device over standard USB (using the 1702 communication channel I believe is for the board). I don't have the U

Edit/Manipulate I2S Bits with Sigma Studio ? (ADAU1701)
Hello, I am feeding my ADAU1701 DSP with digital data (I²S). The data looks like this: , Here, I send a sine on Left and Right channel. Therefore, the data looks the same in both cases (left and right

ADAU1701 Volume Control Using MCU
Hello Bob! I just need to ask about volume control using 8bit MCU as a master to control the sigma DSP ADAU1701 volume using push buttons Everytime i push either Volume UP/DOWN, the MCU writes to the
