A2B Module 2nd generation EVM
A2B EVM provides stereo audio I/O for A2B.
AD2437 based A2B Module
Clockworks’ A2B AB0331 module offers developers a simple way to develop A2B products by creating prototypes based on the A2B module connected to EVM board(s) for the desired peripheral functions. Typically Clockworks’ A2B module is used with ADC or DAC boards, but can also be used with things like class D amplifier devices with direct […]
AudioXpress A2B article series
Clockworks authored an introductory A2B article series in AudioXpress magazine. This magazine is a great resource for both professional and other audio designers. To check out the 4 part article series on their website click the image below.
32 second explanation of Clockworks’ A2B hardware
Clockworks’ A2B and related products are designed for developers looking for fast evaluation, prototyping, and small volume deployment of A2B based systems. We made a little video to help out people with short attention spans…unfortunately it came out 2 seconds longer than the proverbial 30 second video.
USB audio to A2B interface with miniDSP’s MCHStreamer (AppNote002)
During prototyping and development it can be convenient to be able to send or receive audio from a host PC (Windows or Mac in this case) for injecting signals or for monitoring -particularly if using SigmaStudio for A2B topology modifying routing to accommodate testing is trivial. miniDSP offers an easy to use board based on […]
Jitter spectrum measurement with a DSO (AppNote001)
In testing some of the A2B hardware what appeared to be high jitter on the clocks was observed. While specialized scopes & software are available for making jitter measurements one was not available at the time measurements were needed. The basic idea is simple enough – measure the clock edges and see if they are […]
Quick bus powered A2B slave node hack
A quick system was needed where the Clockworks module based A2B node (operating as a slave) could be bus powered to avoid the need for a separate set of power wires. The final goal was to attach some GPIO signals to the module’s AD2428W GPIO lines. While no magic smoke was released, it didn’t work […]

Resistor Noise in Audio: The Sound of Angels Dancing on the Head of a Pin (Presentation from Teardown 2019)
Video from a presentation at Teardown 2019. Unfortunately the audio is out of sync with the video, and a little is missing off the front. This is a based on the work done for the AES paper and the background materials found here (including the audio files for experimenting with audible noise levels). It’s less […]
Audio Builders Workshop Metronome Project source files
Clockworks and Audio Builders Workshop (ABW, a working group of the Boston chapter of the Audio Engineering Society) created a simple Metronome project for people interested in building their own audio electronics. It’s intended as an entry level project for anyone interested in learning about building electronics kits. ABW has “build events” where the parts […]
