The Audio question type allows authors to implement audio recorders into a question. The embedded audio recorder can record, save and playback a students response. It is especially useful for language assessment. Audio questions are not auto scored.

Create a question
Enter a question stem in the Compose Question area. Select question style from the Layout menu below. Then set audio Maximum Length. This parameter sets the number of seconds of audio allowed to be recorded by the student.
The Audio question type has a number of settings that allow you to control and configure audio recording and playing. Under More Options you will see the following toggles that will help you customize the question to your needs:
- Silence stop duration - This specifies the duration of audio silence in seconds after the recording has stopped. This value is set to 0 by default, which means the silence detection is turned off. Insert a value in seconds in this field if you want to enable the option.
- Overwrite Warning - When enabled this will give students a warning that their previous recording will be replaced if they re record.
- Recording Cue - When enabled a beep is played before recording starts.
