100 Things #8: Display Multiple Curves on One Graph

In SoundCheck, it’s easy to display multiple curves on one graph – simply drag and drop a set of measurement data, or even a group of data from multiple devices. This saves considerable amounts of time when comparing a batch of devices, or even testing multiple transducers within a device (e.g. microphone array). Watch this short video to see just how easy it is!

Video Script: Display Multiple Curves on One Graph

Sometimes we take for granted how easy it is to perform certain tasks in SoundCheck until we see how difficult it is using other test systems.

Let’s say I wanted to measure a batch of devices and display the results on a single graph.  Other test systems might require you to go through a multi step process involving exporting, editing and re-importing data But in SoundCheck, all that’s required are a few mouse clicks. Let’s take a look, shall we?

I’m going to measure 5 speakers and show the results on the same graphs. My test sequence measures frequency response and distortion and writes them to SoundCheck’s memory list, and plots each response on their respective graphs. Here is my first measurement.  I have auto-protected the data so it remains in the memory list and doesn’t get over-written when I run the next test. Now let’s measure some more speakers.

As you can see, the data from each additional speaker is automatically added to the graphs so you have a convenient way of comparing devices.

Protected data remains in the Memory List until SoundCheck is closed. When the sequence is closed, the user then has the option to save or discard the protected data as they see fit.

And, like virtually all SoundCheck functionality, this can easily also be incorporated into test sequences for even greater automation.

This convenient functionality has always been available in SoundCheck, right back to the early days when it was just a 2-channel system. Of course with today’s multichannel, multi-transducer devices, it’s more important than ever.
