[AUDITORY] New AudioSpike version 2.5.1.0 released



Dear List

today I have release the new version 2.5.1.0 of the open source freeware

AudioSpike - The free Software Tool for Electrophysiological Measurements using Audio Interfaces

Here's the list of changes:

Version 2.5.1.0, Date: 4.12.2025
-----------------------------------------------------------------------
- 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
-----------------------------------------------------------------------
