The control name for the UI component that sets the level of S2/S3 samples.

· levelControlsS2

Whether volume level controls volume level of signal S2.

· levelControlsS3

Whether volume level controls volume level of signal S3.

· maxOutputLevel

The maximum output level allowed so that no overflows can occur.

· monochannel

To which output channel samples S2/3 come out to.

· monomapping

Channel mapping for playing samples S2/3.

· S1Volume

Volume for the S1 sample.

Method Index

· controlPerformed(ControlEvent, SessionSubject)

Process control events from a subject UI.

· initItemSamples_base()

Sample initialization for this item.

· initItemUI()

· initTest()

In addition to defaul test initialization, creates mappings for channel mappings for S2/3 and calculates maximum output level for avoiding overflows.

Variables

 protected transient SoundSample sampleS1

Sample for signal S1.

 protected transient SoundSample sampleS2

Sample for signal S2.

 protected transient SoundSample sampleS3

Sample for signal S3.

 protected Volume S1Volume

Volume for the S1 sample.

 protected Volume S2Volume

Volume for the S2 sample.

 protected Volume S3Volume

Volume for the S3 sample.

 protected transient Volume currentVolume

The current level.

 protected Volume scaleMax

Maximum volume for samples S2/3. It is used for calculating the maximum output level for avoiding overflows.

 protected int monochannel

 protected ChannelMapping monomapping

Channel mapping for playing samples S2/3.

 public static final int SCALE_LINEAR

Volume scale type is linear.

See Also:

Volume, scaleType

 public static final int SCALE_DECIBEL

Volume scale type is decibel.

See Also:

Volume, scaleType

 protected int scaleType

Type of the volume scale. Not currently selectable, only decibel scale is currently used. Will affect how the variable gain controller affects volume leve. Scaling is a bit different for linear and decibel scale.

See Also:

SCALE_LINEAR, SCALE_DECIBEL

 protected boolean ensureNoOverflows

 protected Volume maxOutputLevel

The maximum output level allowed so that no overflows can occur.

 protected String levelControlName

The control name for the UI component that sets the level of S2/S3 samples.

 protected boolean levelControlsS2

 protected boolean levelControlsS3

Constructors

 public SSMSTest()

Methods

 public void initTest() throws Exception

In addition to defaul test initialization, creates mappings for channel mappings for S2/3 and calculates maximum output level for avoiding overflows. Done by limiting the MCL level range that can be used.

Also, will warn and change sample switching to 'normal' and sequence type to 'free' if they are not so.

Throws: Exception

thrown if an exception occurs during test initialization.

Overrides:

initTest in class Test

See Also:

ensureNoOverflows, scaleMax, sampleSwitching, sequenceType, MCLL, MCLLmin, MCLLmax

 protected void initItemSamples_base() throws Exception

Sample initialization for this item.

Throws: Exception

an exception may be thrown if there are problems

Overrides:

initItemSamples_base in class GenericABCTest

 protected void initItemUI()

Overrides:

initItemUI in class Test

 protected void samplePlay(String name)

Play sample.

Parameters:

name - the name of sample to be played received from the subject UI.

Overrides:

samplePlay in class GenericTest

 public void controlPerformed(ControlEvent e,
                              SessionSubject subj)

Process control events from a subject UI. In this test this method processes the control events of the level setting control for the level of S2/S3 samples. Other control events are passed on to the super-class for processing. In this test the level is also recorded as an answer. The answer is delivered as an answer event from the same component.

Parameters:

e - The control event.

subj - The subject that generated this event.

Overrides:

controlPerformed in class GenericTest

 public void propertyLoad(Properties p,
                          String name) throws IllegalArgumentException

Read parameters for this test from the properties.

Parameters:

p - the properties.

name - the name of this object (not usually used)

Throws: IllegalArgumentException

thrown if parameters are wrong.

Overrides:

propertyLoad in class GenericABCTest
