Version 2.5.1.0

Version 2.5.1.0, Date: 04.12..2025

• new additional spike detection method introduced
  • new spike detection method "Version 2" added, see the manual for changes
  • new button/dialog for rescanning spikes of result files with new spike settings and/or spike detection method
  • new button for 'flipping' raw epoche data (see manual for details)
  • menu item "Adjust spike-length" removed: adjustment moved to "new spike settings" dialog
  • existing ("old") spike detection method "Version 1" enhanced
• Important change: SpikeLength and PreThreshold values now mandatory in measurement templates for spike detection "Version 1"
• Important change: Value of "SpikePosition" in result files changed: now it is the sample position of
  the first sample of the spike within an epoche (before 2.5: sample threshold crossing point within an epoche).
  The new value "ThresholdCrossingPosition" holds the position of the threshold crossing point within the spike.
  Old result files are adjusted accordingly on loading.
• new feature "flip polarity" moved from hardware channels (sound settings) to measurement input channels (electrodes)
• new measurement template values for the new spike detection method features named "SpikeDetectionMethod",
  "SpikeTimeReference", "RefractoryTime", "RefractoryTimeTailFactor" and "InputChannelsInverted" (see manual for details)
• settings dialog restructured
  • new tab for Free Search Settings, some values moved between tabs
  • Sound Settings moved to separate dialog (useful for offline analyes without the need to create 'valid' sound settings)
• position information for positive and negative peak within spikes stored additionally in result XML files
• trigger generation and detection enhancements: Trigger Test allows to adjust trigger properties
• extended main menu
• variable MAT file creation timeout
• stimulus length now displayed in epoche window for results (only for results created with AudioSpike 2.5.1.0 or higher)
• bugfix for rescanning epoches of old measurements with 64-bit version

Version 2.4.2.0

Version 2.4.2.0, Date: 28.10.2025

• bugfix and anhancement of input clipping detector (epoche window)
• bugfix for subwindow positioning
• new option "Autosave complete measurements" available in settings
• new option for electrode inputs: polarity can be flipped to invert the recorded data (epoches)
• new appendix in manual describing a few internal settings that can be adjusted manually using inifile entries
