Reaktion times for an event of an audio file thats beeing presented was created by McTell
Hey all,
I use LS mainly for auditive experiments. I spent some time reading and trying things out now, but maybe - before investing more time - it's better to get a quick answer from the Pro's.
I need to measure reaction times for an event of an audio file thats beeing presented.
The new paradigm illustrates likes this:
1. The mp3 file shoud be downloaded, completely.
2. A "Play-Button" plays the file and along with the click the time is beeing recorded.
3. Certain events happen in the audio stream and subjects task is to react on with a button press/click/tap. And this click should have a time stamp.
In general possible?
Big thanks to all, you were very helpful!

In general, anything is possible.
As you have access to the source code you can do a lot of stuff with Limesurvey.
But from my point of view, you will have to do a lot of customization to get to what you want to do.
And measuring reaction times over a web application is quite questionable anyway, because there can be so many other factors that influence the measured time (delay, slow internet, etc.).
I assume that the times that you want to measure will range in the second or rather milisecond range and I think the internet connection can have a strong impact on this.

Indeed.
That was the reason to put everything in a closed environment. Making sure the sound fully downloaded. And by making a click, playback begins along with local JavaScript doing the timing.
Has anyone ever done that?

But i never do it, no code ready ...

What is then the short text doing? I need to record the timestamp of key stroke or mouse click? I know fundamentals of JS/jQuery, but that might be not enough, and no clue how to start

Have a look at
the workaround for IAT
. It will give you insight on how how to record timestamps into text fields as keys are pressed.
