TAudioSignal Members

The following tables list the members exposed by TAudioSignal.

 
Name 
Description 
 
The property holds any error message after an error has occured. 
 
Number of buffers filled with data to be processed, since the start of the processing. 
 
Number of buffers actually processed, since the start of the processing. 
 
Number of buffers queued, to be processed, since the start of the processing. 
 
Name 
Description 
 
Appends Sample to the end of the signal. 
 
Copy 
Copies signal Data and sampling frequency information. 
 
Compute the CREST parameter. 
 
Returns total number of samples elapsed since start of the processing. 
 
This is ElapsedTime, a member of class TAudioSignal. 
 
Returns a list of CoreAudio devices.  
 
If all Inputs[i] are dirty the function returns true. 
 
When called, the method will pass Update requests recursively to all connected objects. 
 
Notifies all connected components that this component has fresh data. 
 
Convert marks to strings. 
 
Find minimum and maximum amplitude and store the result in the MinAmplt and MaxAmplt properties. 
 
This is the overview for the MonitorData method overload. 
 
This is MonitorOutput, a member of class TAudioSignal. 
 
The method can be assigned to some other component even handler, as a notification that a parameter has changed and that Self should consider a recalculation. 
 
Peak 
Find the maximum deviation of the signal from its mean value. 
 
Recursively processes all connected components backward and calls Reset method. 
 
Pull 
Request recalculation of the entire chain of all connected components. 
 
Calls Pull until pipeEnd is returned.  
 
To ensure skip free recording an playback, audio buffers must have some minimum size. 
 
To ensure skip free recording an playback, audio buffers must have some minimum size. 
 
Size 
Assign the size of the signal from Src. 
 
Start playback/recording. 
 
Returns True, if the signal is Stereo. 
 
Stop processing at once. 
 
Process all pending buffers and then stop. 
 
Recalculate request. 
 
Call this method only, if SuspendNotifyUpdate is True. 
 
Convert values to strings. 
 
Name 
Description 
 
Returns the upper bandwidth edge of the signal. 
 
Returns the lower bandwidth edge of the signal. 
 
Default property to access values of a complex signal. 
 
Dt 
Time between two consecutive samples. 
 
Frequency resolution obtained, if an FFT algorithm would be run on the data. 
 
Must be "Hidden" unless it is published 
 
Must be "Hidden" unless it is published 
 
Number to label the object when it is an item in the List. 
 
Stores the time stamps and amplitude of selected samples. 
 
Stores the maximum amplitude of the signal found by the MinMax method. 
 
MaxX 
Use the MaxX property to store the time stamp (in seconds) of the right most sample. 
 
Stores the minimum amplitude of the signal found by the MinMax method. 
 
MinX 
Use the MinX property to store the time stamp of the left-most sample. 
 
Returns the state of the pipe after the last update. 
 
The length of the signal in seconds. 
 
Set this property to True, to prevent calling OnNotifyUpdate from the Update Method. 
 
Set it to True to indicate, that valid signals will be connected to the Input or Inputs properties. 
 
Default property to access values of a real signal. 
 
Name 
Description 
 
Set active to false to suppress the propagation of the Pull request and the subsequent call to the Update method. 
 
Set the property to True, for the component to call Pull method each time a new buffer is requested. 
 
Return the bandwidth of the signal. 
 
Get or set the number of channels multiplexed in the data property. 
 
Set this property to true, to request computation using complex numbers.  
 
If True, the component will pass on the udpate request to the connected component. 
 
Data 
Stores the result of the processing. 
 
may not have default to allow switching of default precision 
 
Set this property to true to lock changes to FloatPrecision property.  
 
may not have default to allow switching of default precision 
 
Get or set the length of the signal in samples. 
 
Defines how aggressivelly will the MonitorData function attempt to obtain the very latest data (just to be recorded or just to be played back.) The value is defined in miliseconds. 
 
The property keeps the track of the actual frequency of the calls to the MonitorData property. 
 
Defines number of buffers being gueued to be processed. 
 
The event is triggered after the call to the Update method. 
 
The event is triggered just before the call to the Update method. 
 
The event is triggered after the OnAfterUpdate event. Use this event to update any associated charts or graphs or result tables. 
 
If the Input property is not assigned, the component will call OnGetInput. 
 
The event is called after a call to InternalUpdate, OnAfterUpdate and OnDisplayUpdate from within the Update method. 
 
The event is triggered when ParamUpdate method is called. The ParamUpdate method is usually called by component editors when a value was changed by the user and the editor was "Live".  
 
Event triggered when processing starts. 
 
Event triggered when processing stops. 
 
The property holds the statistics for the MonitorData method. 
 
Set it to true, if you want to pause the playback. 
 
Define dynamics of the signal. 8,16 or 24 bit. 
 
Defines the sampling frequency of the signal. 
 
Set WaveDevice to -1, to always use default windows sound device.
