25: Confidence Limits (working from home with SoundCheck)
/in WFH With SoundCheck Videos, Working from home with SoundCheck /by ZarinaFollowing questions from some SoundCheck users who had watched #3 in this series (sequence optimization), Steve Tatarunis takes a look at the measurement confidence function in SoundCheck, and explains the trade-offs between speed and accuracy when choosing a step size to optimize your measurement.
24: Instrument Highlights (working from home with SoundCheck)
/in WFH With SoundCheck Videos, Working from home with SoundCheck /by ZarinaAnastassia Tolpygo demonstrates some neat features of virtual instruments that you may not have seen before. These enable you to make a quick distortion measurements, accurately measure frequencies at very high resolution, and plot and save curves over time using just the virtual instruments without the need for a sequence step.
23: Offline Statistics (working from home with SoundCheck)
/in WFH With SoundCheck Videos, Working from home with SoundCheck /by ZarinaIn this short video, Steve Tatarunis takes a deeper dive into the Offline Statistics functionality in SoundCheck, demonstrating how you can run statistical analyses from home on data from your production facility or overseas contract manufacturer. No hardware required – just your computer with SoundCheck and some measured data!
22: Save To Office (working from home with SoundCheck)
/in WFH With SoundCheck Videos, Working from home with SoundCheck /by ZarinaWhat better way to perfect your data output options than when you have some uninterrupted SoundCheck time at home! SoundCheck saves data in many different user defined ways, and saving to Office apps such as Word and Excel is just one of them. Most people just use the default settings to create a quick visual output, but the key to making your data work for you is Custom Templates and Autosave Steps. Watch this short video to learn more.
21: Limits (working from home with SoundCheck)
/in WFH With SoundCheck Videos, Working from home with SoundCheck /by ZarinaWhile you are working from home, optimize your SoundCheck sequences by tweaking your limits for optimum quality and yield. Devin Vaillancourt explains the different types of limits available (absolute, floating, aligned, and more), and once you have explored the different types, you can test out different limit configurations using saved data from products that you have already measured.
20: SoundMap (working from home with SoundCheck)
/in WFH With SoundCheck Videos, Working from home with SoundCheck /by ZarinaCam Ruffle-Deignan walks you through a demonstration of SoundMap, SoundCheck’s Time-Frequency analysis module, showing how Short Time Fourier Transform, CSD, Wigner Ville and Wavelet analyses can be used for detailed offline analysis of devices. Time-Frequency analysis methods are useful for impulse response analysis and detection of loose particles and Rub & Buzz in loudspeakers and identification of transient effects such as drop out in digital devices including VoIP and Bluetooth headsets.
19: Exploring Custom Steps (working from home with SoundCheck)
/in WFH With SoundCheck Videos, Working from home with SoundCheck /by ZarinaLearn how to level-up your SoundCheck sequence using Custom Steps – LabVIEW VIs that can be used as steps in SoundCheck sequences to implement operations that cannot be done natively in SoundCheck. A selection of custom step templates built into SoundCheck accelerates the development of custom steps with examples that allow you to open and close virtual instruments, control turntables, read/write serial numbers and even open any .exe file such as a Python script. Devin Vaillancourt demonstrates how to use this powerful feature.
18: Displaying multiple data sets on one graph (working from home with SoundCheck)
/in WFH With SoundCheck Videos, Working from home with SoundCheck /by ZarinaThere are many times when it is desirable to display multiple data sets on one graph – for example, testing multichannel devices, comparing devices, comparing measurements to the fundamental, comparing EQ curves, etc. In this short video, Steve Tatarunis demonstrates how to display multiple curves on one graph, both by simply dragging and dropping and also automatically via a sequence.
17: Predicting Listener Preference Using the Harman Target Curve (working from home with SoundCheck)
/in WFH With SoundCheck Videos, Working from home with SoundCheck /by ZarinaIn this short video, Cam Ruffle-Deignan walks you through how to predict listener preference based on the Harman Target Curve. This free sequence (which can be downloaded here) can recall previously saved data as well as capture new data, making this a great ‘work from home’ project if you have previously saved measurement data on your headphones.
16: Batch Processing & Analysis (working from home with SoundCheck)
/in WFH With SoundCheck Videos, Working from home with SoundCheck /by ZarinaCam Ruffle-Deignan demonstrates batch processing and analysis – powerful tools that enable groups of waveforms (or other forms of data) to be processed with just one step, either in a sequence or offline.This simplifies the processing of large volumes of data in offline mode, and is useful in multi-channel test system sequences.
15: Data Portability (working from home with SoundCheck)
/in WFH With SoundCheck Videos, Working from home with SoundCheck /by ZarinaDevin Vaillancourt demonstrates both manual and automated ways to save data from SoundCheck to be used with other programs including Excel and Matlab. He also shows how to save waveforms as .WAV files which is an important tool for open loop testing.
14: Customizing your SoundCheck Desktop & Color Palette (working from home with SoundCheck)
/in WFH With SoundCheck Videos, Working from home with SoundCheck /by ZarinaDid you know that you can set your own color palette preferences for graphs and customize your SoundCheck desktop? Cam Ruffle-Deignan shows you how.
13: Sequence Portability (working from home with SoundCheck)
/in WFH With SoundCheck Videos, Working from home with SoundCheck /by ZarinaNeed to collaborate on a project? Devin Vaillancourt shows you how to export a sequence (including one with dependent files) to share with a colleague.
12: Remote Desktop troubleshooting (working from home with SoundCheck)
/in WFH With SoundCheck Videos, Working from home with SoundCheck /by ZarinaSometimes you may want to use your laptop at home to remotely run tests on your computer in your lab. You may need to adjust your audio signal paths to do this successfully. This short video shows you how.
