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

ADAU1466 + ESP: Readback LevelRTA
Hi All, I am working on a DSP solution where i use ESP32 to fully control the ADAU1466 @ SPI. I have many basic functions working and now i would like to provide input and output levels to the web int

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

ADAU1701 Low Instruction Level Detection Readback
Hi! I need to read back some signal levels to the microcontroller in my current project via I²C. This works as expected with an "Envelope Peak" block together with a readback cell. These two cell

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

SigmaStudio new level detectors
Hi all, I see in latest Sigma Studio release two new level detectors: Level Detector w Numerical Display Level Detector w Numerical Display. Low DSP MIPS. Average enable. In the .trap file I found mul

adau1701 internal peak and rms levels wrong!
I am using the circuit blocks RTA thats supposed to show level in db and PEAKENV in conjunction with READBACK to display the HEX of the peak value. I have calibrated the input level such that the RMS

ADAU1701 reading RMS detect display value from uC
Hi all, in a project with ADAU1701 and SigmaStudio 3.8 I use a MONO RMS Detect (Display) block as limiter. I need to read the signal and compression levels from an external microcontroller. I didn't f

Interfacing ADAU1701 with AD1955 (2)
As a bit of a continuation from Interfacing ADAU1701 with AD1955 Has anyone successfully used an ADG3304 for I2S level translation from an ADAU1701? Or could anyone offer an educated/experienced guess

ADAU1701 i2s outputs low
I am using the ADAU1701 DSP at the heart of a audio mixer using the 4 x i2s inputs and 4 x i2s outputs With a PIC setting up and controlling the DSP. The pic supplies master clock and the DSP creates

Interfacing ADAU1701 with AD1955
Hi: I am trying to send the I2S output from ADAU1701 acting as master to a DAC board built around the AD1955. Questions: 1. The ADAU1701 datasheet recommends on p18 that MP11 be used to derive MCLK. N

1701 how to make tone volume dependent on input level
I am using the 1701 evaluation card. I would like to adjust the volume/level of a sine wave tone such that it would be dependent on the RMS input level of the audio. For example if the RMS input level

Calculating the difference (in decibels) between the RMS levels of two signals
Comparing the linear level of two signals is fairly simple in SigmaStudio. You can basically calculate the envelope of each signal (using peak, MS, or running average), and then subtract the two outpu

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
