Problem with ADAU1452 and SigmaStudio 4.7, audio amplitude oscillates uncontrolled
Hello, We've been using for a long time Sigma Studio with a ADAU1401A for an old project. We upgraded to the ADAU1452 for having delay functions, and we re-made the program to be the same. We've encou

Adding some information that is missing from the DSP checksum calculation documentation page
The DSP Wiki page at https://wiki.analog.com/resources/tools-software/sigmastudio/toolbox/basicdsp/checksum discusses how to calculate the checksum for a running DSP but some important information was

Unable to selfboot
Hello Everybody, I use ADAU1450 in my own design, which is based on my last project which used ADAU1452 (which is flawless). E2prom is 24LC512, I2C is used for USBi and EEPROM communication. SS_M is t

Process each channel in a TDM4 input stream
Hi, I stream TDM4 signal to ADAU1452 sigmaDSP through SDATA_IN0. I want to process each channel from this TDM4 signal (Filter and maybe more). How can I do it? When done processing each channel, I nee

Is it possible to implement preset settings on a stand-alone ADAU1452?
Hello All, For a new design I would like to use only the ADAU145x DSP without a controlling microchip. Customers will be able to write their own DSP application in SigmaStudio and upload it into an fl

External SPI delay for long delays
Hello, I have a PCBA with an ADAU1401 performing some ADC-DSP-DAC tasks and it works pretty fine. now I need to add a big delay to the audio, so I came to the possible solution of codec+DSP. I am tryi

ADAU1463/67 no SDATA Output on Slave Channels
Hello all, i'm using an ADAU1463 as 8ch I2S Output as follows: - Serial Output Clock Domain0 is Master, SDATA_OUT0 carries 2 Signals (L/R) - Serial Outputs 1 - 3 are all set as slaves to Clock Domain0

ADAU1452 maximum self-boot image size, and sharing EEPROM
Hello, I'm having some trouble determining the worst-case self-boot image size which could be possibly generated by SigmaStudio for the ADAU1452. If I add up the total size of DM0, DM1 and program spa

ADAU1451 Multirate processing and clocks/start pulse/sampling rate settings problem
Hi, I’m having some troubles with multirate processing on the ADAU1451 (scheme below). I want to receive : 1) audio data at 48 kHz 2) have a first stage of processing at 48 kHz 3) then upsample the au

UpSampling algorithm version 1.02 broken
I have just tried the latest version (1.02) of the Upsampling algorithm with SigmaStudio 4.6 and an ADAU1452. I am running at 96kHz sample rate and downsampling 16x, then Upsampling, with no filtering

What is the "power-down" state of the ADAU145x?
For standby (soft powerdown) operation we need to of course draw minimal power, and I'd like to avoid switching the IOVDD off, mostly because voltages on the potentially still-active I2C bus can destr

ADAU145x AES/EBU
We're considering adding AES/EBU reception (only) in a new design (probably ADAU1451). The DSP supports SPDIF natively, which is very close, but disclaims AES. Why is that? If we add a proper isolatio

ADAU145x Version control configuration
Hi I'm facing an issue that I can't get around : In order to maintain the software on our microcontroler, I would like to be able to get the firmware version of the DSP softwares that are inside the s

ADAU145x Sine Tone oscillator dB unit
Hi, There is a Sine Tone oscillator module for ADAU145x. Please let me know the exact unit of gain [dB]. Does this [dB] mean [dBFS]? Thanks and Regards, sigmastudio adau145x SigmaDSP

About indirect parameter module
Dear support member Can Indirect parameter module avoid pop and click noize like a sofoware safeload registers? If no, could you tell me how to avoid them when we use Indirect parameter module, please

Capture sound output on a simulation
Hello everyone. I'm completely new to SigmaStudio. I need to simulate the input/output of the DSP with the built-in simulation, since I don't have the hardware (yet). I'd like to have an input, i.e. a

adau145x watchdog?
The ADAU145x datasheet states w.r.t. the watchdog: The counter is reset to the maximum value each time the program counter jumps to the beginning of the program to begin processing another audio frame

[Bug Report] ADAU145x multi rate problems
SigmaStudio version 3.13 Windows 7 Pro 64-bit Service Pack 1 I am seeing some really strange behavior with the new mulitrate blocks on an ADAU1451. I created a small project to show the issue: The Sig

Where are the multi rate blocks?
I see other posts of people using the multi rate blocks for the 145x, and they are also listed here. I have the latest version of Sigma Studio installed (3.13), but I don't see the multi rate blocks a

ADAU145x software safeload address changes, not included in header file
See page 80 of the 145x datasheet. It says that the software safeload addresses are determined by the compiler, so they may differ from the "defaults". This is indeed true... and it says to look at co

Output "with pullup"?
I've been puzzled a bit by the GPIO modes of the MP pins of the ADAU145x... Input (0b000) is clear: output register is ignored, input registers shows pin value. Option 0b001 is a bit vaguely described

DVDD regulator layout, ADAU145x (trace lengths)
Due to some design constraints, I'm having trouble fitting the (large) DVDD regulator (STD2805T4) next to Pin 3, where it usually goes (VDRIVE). Can I move this package (and its resistor/caps) a 2-3 i

An ADAU1452 "Vocal Sweetener"
Spectral analysis of several American Idol contestants' voices showed me that those which sound good to me also feature a strong second harmonic. It's well known that tube guitar amplifiers are prefer

ADAU145x I2C Master Port
Hello! I see in the ADAU145x there is a way to use the I2C control port to configure peripherals. i was wondering if it's possible to use the I2C port during operation as well. For example, i want to
