getVoiceRecorder(id).log() (since PennController 1.8)
Will add a line whenever a recording starts and whenever it stops.
Note that a line with the filename of the recorded sample is always logged anyway even if you do not call
.log(), so you can identify it in the output archive.
Adds a media player and a recording button to the page and waits for a sample to be recorded. The filename will contain the timestamps of when the recording button was clicked: one line for the first click (starts recording) and one for the second click (stops recording).
