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.
Limits Tutorial
/in On-Demand Training, On-Demand Training Videos /by ZarinaThis series of 3 short videos explains how to set up limits in SoundCheck from basic fixed and floating limits to advanced limits that use recalled curves and values from the memory list.
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.
