NEW FEATURE: Sound Recording with SoundIn and SlideSoundIn [23245]

This article is currently being updated by our staff.

Detail
This feature allows for the ability to record a subject's verbal responses within E-Prime. This includes the use of the SoundIn, SlideSoundIn, and SoundCaptureDevice objects.

 

SoundIn
The SoundIn object is a Procedure-level object used to capture a subject's verbal responses.

 

SlideSoundIn
The SlideSoundIn object is a Slide sub-object used to capture a subject's verbal responses.

 

SoundCaptureDevice
The SoundCaptureDevice provides an abstract representation of the sound capture hardware currently installed on the system.

SoundIn/SlideSoundIn Properties

 

Filename - Name of file used to save the audio captured by this object. The default value is '@Auto' which is a special value for this field that instructs E-Prime to automatically generate a unique filename for each successful run of a sound capture object.

StopAfter - Determines if the SlideSoundIn should be stopped when the object ends.

EndSoundCaptureAction - Determines if the currently running object should terminate, jump or do nothing once the fixed buffer has been filled.

BufferSize - Amount of audio to be captured (represented in milliseconds).

SoundCaptureMode - Determines how the audio is captured. NOTE: This only supports 'Buffered' mode, currently.

 

Runtime Properties
Buffers - Collection of SoundCaptureBuffers used to store recorded sound data.

ActiveBuffer - Index of the active buffer from the Buffers collection.

NOTE: The ActiveBuffer is automatically saved to disk via the .SaveToFile script command at the end of the currently running Procedure, assuming the Filename field has been defined.

Stop - Stops the capture. StopAfter will determine if sound capture is stopped when object .Run ends.

Record - Starts the audio recording. This is automatically called by .Run.

 

Logging
The SoundIn/SlideSoundIn objects do not currently support setting any properties at this time. This must be done manually via InLine script using c.SetAttrib.
