External Control of SoundCheck Seminar

SoundCheck has led the way in production line audio measurement for over 25 years with its sophisticated suite of audio measurement algorithms that offer precise measurement, fast throughput, excellent noise immunity, and world-class reliability. However, many audio manufacturing factories are moving towards large, highly customized, integrated test configurations to evaluate products, not only for audio integrity, but often video, visual and other performance defects. This seminar explains how external control capability brings the advantages of SoundCheck into your automated test environment using any programming language compatible with TCP/IP  including C, C+, Python, LabVIEW and more.

External Control demonstrations include:

  • Enabling TCP-IP in SoundCheck, and an overview of commands
  • Using external control to open up and run a SoundCheck sequence using a python script, and returning data for use in any application
  • Changing test parameters via external control, so that test procedures can be simplified by adapting test conditions on the fly for different products
  • Loading, playing and controlling volume of  a test signal on a DUT  using a custom step in a SoundCheck sequence.
  • Using external control to automatically equalize wave files loaded into SoundCheck via TCP/IP
  • Using MATLAB with SoundCheck

Presenters: Mark Latshaw, Pranav Swaroop
Duration: 30 Mins

100 Things #11: External Control Using TCP/IP

Factory automation is easy with SoundCheck because it offers full external control via TCP/IP. This means it can communicate with any programming language that can send and receive TCP/IP commands such as Python, C# or LabVIEW. This means that SoundCheck can be opened, run, and even parameters passed into it from an external script. The possibilities for integrating SoundCheck into a large-scale factory test system are endless.

Video Script:

Did you know that factory automation is easy with soundcheck? It offers full TCP/IP control, this means that soundcheck can communicate with any programming language that can send or receive TCP/IP commands like python c-sharp or LabVIEW.

The program can be running locally or over the network on any operating system. Using these commands, there is no need to even have operators open soundcheck directly on the factory floor. Instead, a script could be written to open soundcheck in the background, run a specific test sequence, then pass the output back to the external program or data management system.

Furthermore, sequence parameters such as limits and stimuli can be stored externally and pulled in via TCP/IP. This means that the same sequence can be used for many different products with minimal operator intervention, reducing the sequence maintenance burden. Audio is often not the only thing being tested on production lines, and TCP/IP control allows powerful SoundCheck sequences to seamlessly integrate into full production test suites.
