Auto Mute Implement
Hi everyone, I’m working on an ADAU1466 project in SigmaStudio and would like to implement a “mute on silence” (auto-mute) feature similar to how commercial DSP amplifiers mute their outputs when no a

ADAU1701, Initial state of GPIO, controlling MUTE on DRV632
Hi Forum I'm working on a ADAU1701 board, where I'm using DRV632 buffers as output filter from the DACs to ensure pop free startup from single supply. DRV632 has a Mute pin (pin 5) which is active low

Why my output auto-mute when i put a low volume in input on an ADAU1701 ?
When i play a low signal in input my dsp seem to auto-mute the output. I don't think that came from my schematic knowing that i only put and input block and an output block with nothing between. I ols

ADAU1452 Detecting the end of a slew-rate limited mute transition
Hi. I have a mute block with a custom slew type (0xAAAA), which gives me a slow fade to mute over about two seconds. Rather than hard-coding the transition time in the MCU, I'd rather get this informa

Remove audio feedback with ad1940(dsp)
Hi everyone It is currently designed with 4 microphone inputs and 2 line outputs. DSP CHIP AD1940 (4 mic inputs) + (1 line output feedback input) = 5 total. I'm testing with SIGMASTUDIO and it's not w

ADAU 1452 Need help with the input selector and the MUTE button
I am an inexperienced user of Sigma Studio. 1. I ask you to help with a real-life example of a project with a switch between two inputs controlled via the AUX PIN switch button. 2. How to make the fun

Internal Mute Control (ADAU1452)
Hi there, I have multiple outputs from my ADAU1452 that each have an individual mute. This is great. However, it would be nice to have one MUTE control in my design that would mute all of the outputs

Toggle mute on EVAL-ADAU1787z
Hi, I see that for the SigmaDSP, there are many blocks that can be controlled via GPIOs on the board. For the FastDSP, there don't really seem to be any. Is there any way to simply toggle a mute block

ADAU1701-Mute problem
PDF Dear ADI Please see my project of a simple crossover module. When I pressed mute1 block We can hear a strong popping in the speakers. What is causing this? What can I do to eliminate this problem?

Change parameter before selfboot is enabling audio output - ADAU1452
Hello, we use selfboot to run the DSP program and at the moment we have the problem that the volume and mute are written by the uC over I2C which works fine but at boot-time the selfboot loads the par

Both Momentary and Latching Mute
I have the following hardware switches in my 1701 PCB: a pushbutton switch and a DIP switch. The user can currently press the pushbutton for a momentary mute. I'm trying to figure out how to give the

ADAU1761 signal leak in mute?
I connected a microphone to input 1 of the ADAU1761 EVB in single-ended mode, then I attached an amplified speaker to the stereo output, setting the speaker volume to max. Starting from a working outp

Logic controlled mute
I am using an ADAU1701 and would like to mute the audio signal within Sigma Studio at the output depending on the status of logic and a few GPIOs. I am not sure what block to use that could be control

Simple Mute with GPIO?
How would I implement a simple mute function in SigmaStudio, using a push-button on a GPIO? I don't want volume control, just a single button that cleanly mutes/unmutes the audio. Thanks! --> freddie
