  • Fixed pulse train splitter guard time
  • Fixed problem setting up Percentile sound level parameter
  • Fixed Speech and Noise parameter calculation outside speech freq range
  • Fixed naming conflict for default measurement setup
  • Fixed initialisation of rotation step (measurement - location)
  • Cleared intermittent option when 'None' stimulus selected
  • Changed skip deconvolution handling to retain stimulus and source filter info
  • Allowed selection of lines, bars and dots in both param vs dist as param vs freq graphs

ELA test signals

The above test signals are coherent for a FFT size of 2^16 (65536) samples.
Dirac will (pre-)average as many FFT lengths as will fit in the measured signal.
Use a capture length of 10s and a sample rate of 48 kHz for ELA measurements.
