Registers a channel (left, right or multichannel).

Namespace: ExpSuite
Assembly: FrameWork (in FrameWork.exe) Version: 1.0.0.0

Syntax

Visual Basic
Public Shared Function RegisterChannel ( _
	ByRef st As STIMULUSPARAMETER _
) As String

Parameters

st
Type: STIMULUSPARAMETER%
Stimulus parameters.

Return Value

Empty for no errors, error string otherwise. Additional changes in st:
  • .sTimeBase calculated using .lSamplingRate (only in acoustical mode)
  • .sTimeBase, .szFirstName, .szLastName read from the fitting file (only in electricalRIB mode)
  • .lSamplingRate calculated using .sTimeBase (only in electricalRIB mode)
  • .szImpType and .iImpType determined from fitting file (only in electricalRIB mode)

    • Remarks

    Register a channel (=ear, side: left=0, right=1, multichannel. Not acoustical (frequency) channel!).
    Usage:
  • Call it after Init() for each channel you have.


    • RegisterChannel is called by framework on connect. Don'''t call it again.


    st.lChNr must be valid on calling RegisterChannel:
  • In acoustical mode, set st.lSamplingRate [Hz] and st.lResolution [bit]. Then, the .sTimeBase [us] will be calculated from .lSamplingRate.
  • In electricalRIB mode, set .szFittFile to the name of a valid fitting file. From this file some fields of st will be set (e.g. first and last name and time base).

    • The field .lResolution will be ignored in this mode.

    Set before calling RegisterChannel:
  • .lChNr to a valid audio channel.
  • .lSamplingRate (only in acoustical mode)
  • all items of freqPar()
  • .szFittFile to a valid fitting file (only in electricalRIB mode)
  • default values for electrode, pulsenr, pulseperiod, offset


    • Activities:

  • Logging
  • Determining the number of audio channels for auto naming mechanism
  • Copy fitting file to the working directory
  • Update of STIMULUSPARAMETER
