Read level detector via I2C and convert data
Hello, I'm picking up on this old topic ADAU1701 Low Instruction Level Detection Readback I want to read back the level meter data and process it in my controller but I'm stuck with the final conversi

ADAU1467, Sigma Studio v4.7 different Level detectors show different signal levels
I am currently testing a custom board using ADAU1467 and ADAU1361. Currently I want to verify that the DAC of ADAU1361 behaves as expected. Therefor I create a test tone (sine 1kHz, 0dB) with ADAU1467

Single Level Detector w Numeric Display Hold and Decay no effect
Hey together, we are using on our project the "Single Level Detector w Numeric Display" on and ADAU1467. Now we have the requirement to modify the attack, hold and release for this block. In SigmaStud

Level Detector
The signal detection is negative, can it be understood as a positive value? Does - 45dB represent 45dB? I don't quite understand. I am using the MFXLMS module to conduct a sound pipe noise control exp

Compressor input level appears to be displayed/calculated incorrectly
During some recent work, I have been using one of the compressor blocks (Dynamic Processors/Peak/Standard/Full Range/Standard Peak). I noticed the "IN" Level displayed on the level indicators appears

Single Level Detector in ADAU1452
Hi, I use Single Level Detector to read level in my program. I find that the data from 1452 is 4 bytes which doesn't contain the sign bit, so I think it's not 8.24 format. I have the following questio

Read feedback signal level with SPI
Which level detector to use for get signal level? I need read over SPI signal level. In sigma studio is more level detectors, which show me signal level (average in given time). How can I read it with

How to use 1452 or 1701 make a signal level detector to make LED has different brightness while signal strength change?
Hi, I want to use 1701 and 1452 to make a level detector to detect the signal strength, but I don't know how to use blocks to make led brightness will follow the signal strength. The led brightness le

adau 1772
Hello everyone! we are currently designing a new product, based on ADAU 1772 audio processor. We need to measure RMS value of the signal for at least 0.05s. We trued the Single Level Detector (SigmaSt

ADAU1452 T-Connection, Readback, Level Detector
Hello guys, I have noticed a strange behavior of the T-Connection in combination with DSP readback within my ADAU1452 project. My intension was to read the current signal amplitude of multiple channel

VAD for ADAU170x
There's no Vocal Activity Detector block for the ADAU1701/2 so I built one for my application. This one adapts to input levels that vary around nominal, as one might find in use. It works by comparing

24db Level detector
As internal gains of 24db are possible in SigmaDSP processors it would be useful to have level detectors that could indicate this, whether by definable range or simply having a 24db max rather than th
