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

Current Maturity of Custom C/C++ Development on HiFi 3z Core?
Dear Team, We are evaluating the ADAU1797A for a hearable/audio application and need to implement a custom feature extraction algorithm (statistical/spectral analysis of the incoming audio stream) dir

3rd party / licensed algorithms like SRS TruBass
previouly i find that 3rd party like SRS ( now is apart of DTS ) or BBE have port some algorithm of them to SigmaStudio but seem like i cant contact SRS for Trubass trial license right now,so any idea

Mirror image of the compressor gain level
Hi, The diagram shows a circuit that, when a certain threshold is crossed, adds a bandpass filter tuned to 63Hz to the signal. I'd like to add a complementary circuit, meaning one whose gain is the mi

SigmaStudio+ Indirect Parameter Accees Table
In old SigmaStudio you could add a parameter to the IPAT with a simple mouse right-click. Is there a similar feature in SigmaStudio+? I can only add it via the IPAT table but it gets annoying when the

ADAU1452 + AD1938 Setting I/O problem
Hello, I bought a two-board set consisting of an ADAU1452 DSP and an AD1938 codec. I managed to get it up and running using a modified '192i2s.dspproj' test file. The sound quality is excellent. In my

Latency Details for Sigma DSP
Dear Team, For the Sigma DSP processor would like to understand the overall system sample delay in the following cases: 1. When receiving and transmitting audio data through the serial port. 2. When r

time dependencies in compressors
Hi, It's me again, and I have another question about compressors :-) I'm trying to implement automatic gain control, including a noise gate, in a range of about 20 dB. So I used an RMS compressor bloc

SigmaStudio+ Sample rate propagation
I found out that the T-Connector would not propagate sample rate downstream. Remove the T-Connector and connect straight to the next block and the block's sample rate follows upstream. Does anyone hav

SigmaStudio move to 192KHz from 48KHz
I've been asked to reconfigure our dev board to 192KHz from 48KHz. So I decided to start with the eval board first. I asked AI for some help with this but it gave most of the registers different names

Sigmastudio for Android devices
Hi, I apologize for asking this question here. I just don't know where to look. Is there a programming environment similar to SigmaStudio where you can build an audio processing block and then run it
