Online Training: Advanced Analysis

Sept 15 at 9.00am US East Coast time (3pm Central European Time, 2pm UK time) and 2.00pm US East Coast time (11am US West Coast time)

In this 2 hour training, we will be taking a deeper dive into some of the more advanced features of the analysis editor. This will be useful for anyone with a basic understanding of SoundCheck setup, calibration and sequence writing who is looking to add value to their measurements by optimizing their test procedures. We will be taking a closer look at how to configure various analysis algorithms, and the impacts of the chosen settings on measurement confidence and speed. This training offers value to both R&D and production users. We will cover:

  • Understanding and configuring the distortion options in SoundCheck’s Harmonictrak algorithm, including how to select the best option for your application
  • Configuring the Loose Particles algorithm to detect transients in waveforms to catch manufacturing defects that may not be highlighted using frequency based analysis
  • Using SoundCheck’s measurement confidence option to adjust the stimulus to obtain the best trade off between speed and accuracy
  • How to analyze ‘real world’ test signals (e.g. multitone, noise, music, speech) for measuring devices that do not perform well with sine wave signals (e.g. telecoms, those including DSP)

This training is free to support contract holders and $79 for others.

Online Training: Basic Sequence Writing (European Schedule)

Sept 23 at 3pm Central European Time, 2pm UK time, 9am US (East Coast) time [Note: rescheduled from original date of Sept 8th]

The ability to quickly generate test sequences is one of the most powerful SoundCheck skills you can acquire. We are bringing a 2 hour basic sequence writing course to the comfort of your own home with our new online training at a convenient time for our European customers.

This 2 hour course is a condensed version of the basics of sequence writing from our popular 2 day training class. We will start from the beginning, explaining how to determine the test parameters and hardware that will meet your specific test requirements. We will look at best practices for creating a sequence, and finally we will assemble a sequence from scratch. This course is ideal for novice SoundCheck users, or those who have been using SoundCheck with sequences that others have written and who are ready to start developing their own. This training is free to support contract holders and US $79 for others.

Audio Testing with SoundCheck at Sound Hub Denmark

February 25th, 2020. 8.30-17.00

Learn how to measure audio quality of both simple and complex modern audio devices, in both R&D and production environments. Get to know the basics of SoundCheck; one of the world’s most popular audio test software systems, and learn about how to build a test sequence incl. recommendations for the equipment used. Additionally, you will get familiar with specific methods and conditions applied for voice-activated audio testing for e.g. automotive among others.

Join us for an inspiring day, where the Founder and President of Listen, Inc., Steve Temme from US together with Danish representatives and people from GRAS share knowledge about do’s and don’ts.

Sound Hub Denmark has the software and recommended equipment in house to further assist you after this course.

Program Outline

8.30–9.00: Sign-in & welcome

9.00-12.00: Audio Measurement Basics: What to measure and why

  • Learn about different test configurations and the products you need for a test system (software, microphones, interfaces, chambers etc.)
  • Understand the basics of SoundCheck – one of the  world’s most popular audio test systems used on over 10,000 production lines worldwide
  • Learn how to build a simple test sequence for speakers and microphones in SoundCheck, and how to adapt this for different products
  • Common challenges and pitfalls with audio testing
  • Transitioning test from the R&D lab to the production line

12.30: Light lunch

13.15-16.00: Voice-Activated Device Testing, Automotive, smart speakers, hearables

  • Automotive infotainment systems, hearables, smart speakers and many other audio devices are now voice-activated. Such devices are complex to test as they have numerous wired and wireless connections and often contain signal processing, both on the record and the playback side. This means that their characteristics change according to ‘real world’ conditions of the environment that they are used in, such as automotive cabin and roaad noise, background noise, playback levels, and room acoustics. Furthermore, many aspects of the device may need to be tested, ranging from voice recognition to music playback, operation as a hands-free telephone, and even hearing assistance. Often measurements need to be made at different levels and different environmental conditions. In this session, we will discuss the test configurations, tools and techniques that enable accurate measurement of the audio performance of such devices under the many various real-world conditions in which they are used.

16.00-17.00: Hands on and drinks

Space is limited so please sign up on the event page on the Sound Hub Website.

Recall Tutorial

A new series of 3 short videos guides the user through SoundCheck’s various recall capabilities. SoundCheck’s ‘recall’ functionality allows previously saved data to be brought back into SoundCheck where it may be used in test sequences, for example data from a golden unit, weighting/correction curves or limit curves.
The first video covers the basics, and the other two focus on recalling text files and wave files respectively.

Recall 1: The Basics
Recall 2: Recalling Text Files
Recall 3: Recalling Wave Files
