PennController.InitiateRecorderGlobal Commands

PennController.InitiateRecorder( url )

or PennController.InitiateRecorder( url , message )

Use this to specify the URL of the PHP file to upload the audio recordings collected during the experiment.

InitiateRecorder creates a PennController trial asking for the participant’s consent to record audio samples. You can specify a message to replace the default one. Use the label command on it to determine when it should appear in your sequence of trials.

Example:

InitiateRecorder(
    "https://myserver/uploadVoices/saveRecordings.php"
    ,
    "This experiment collects audio recordings. <strong>Once you grant it access to your recording device, you will be notified of whether you are being recorded by a label at the top of the page</strong>"
)
.label("first-trial")

newTrial( "second-trial" ,
    newMediaRecorder("recorder", "audio")
        .print()
        .wait()
)

Adds a page asking for the participant’s authorization to use their recording device, using a custom text message.
