ADAU 1701 - Output noise vs sampling frequency
Hi all, I'm using adau1701 for an active dual channel amplifier to be used in 2-ways loudspeakers. The dsp is used to drive differentially each input channel of the class d amplifier using an active f

Noise reduction algorithm module for Fs=48kHz
Sigma DSP has noise reduction algorithm module for ADAU1761. Unfortunately, it runs only for Fs=16kHz. What’s need to be done to run it for Fs=48kHz. Thanks Mark Audio Signal Processors noise reductio

Huge project to fill up a ADAU1452 and make it do something
The new ADAU1452 is quite the beast among SigmaDSP processors. With about an order of magnitude more capability than the lowly (but quite useful) ADAU1701, one wonders what applications it may find. I

ADAU1772 - Active Noise Reduction?
Hi Guys, I've had to ditch the use of the ADAU1701 for my application. Too many issues getting it working and also it appears that the latency from the ADC to DAC will be too large for what I need as

Performance of ADI's New FullFsNR Block
Recently the SigmaStudio team at ADI produced a prototype block that can reduce background noise in speech signals. Presently it's not built into SigmaStudio, but can be downloaded and installed follo

Is there Noise reduction function supported 44.1kHz and monoral sound?
Hello, One customer need a reduction function block on ADAU1761. In the customer application, some certain audio stream have like a white noise after ADAU1761. They try to remove this noise using Nois

ADAU1761 noise removal algorithm
Hello, I has applied nosie reduction which is ADI's own algorithm on ADAU1761 for my application. From experiments, I verified that that algorithm is effetive in reduction of noise under 100Hz. Howeve
