ASRC Inter Sample Peaks - ASRC Input with gain
Hello EZ, I have successfully built my own 8 channel DSP based on the ADAU1466 and AK4493 DAC's. Now that the hardware works I am trying to get the hang of the more intricate parts of the DSP world. M

ADAU1467eval board DAC stage volume attenuation
hi all, i've got an ADAU1467eval board, I've done a couple of apps for it, mainly to drive fullranges, mids and sub speaker thru with a multichannel power amp fed with crossed over and equalized signa

Conditioning/filtering of noisy AUXADC input
Hello EZ, I have build a DSP using the ADAU1466. It has been working great for a while know. However, I have mooved it to a new case with a significantly longer wire run for the potentiometer that is

Volume control from microcontroller
Hi all, I was wondering If it’s possible to control the volume output of the DSP (in self-boot mode) from a digital pin of a microcontroller connected to a multi-purpose pin of the DSP. Any suggestion

Volume control intermittent crackling
Hi, I am using this simple low pass filter with volume control and having issues with crackling sound when changing volume. This "crackling" is more like an explosion since it goes into 250W RMS sub :

DSP volume control or DAC volume control - which should I use?
I am using ADAU1452 for crossover and EQ functions, then I reclock the signal with a FPGA reclocker, then send the signal to two AK4490 DACs, which have built-in volume control and operate on 32bits.

ADAU1452 volume control problem
Hi I have 2 questions here. the input of the design is like below. using a mixer to mix 5 input channels into one, to avoid cutting distortion, set each input to -20db gain. here comes the question: w

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

Volume control dependent noise in ADAU1701
Hello, Our application has 8 steps x 4dB ( =32dB) volume control in FW. It ranges so that max volume gives +12dB gain from input to output and min volume attenuates -20dB. 18k ADC resistor is used giv
