Description

  • Igor Pro from Wavemetrics, Inc. is "an interactive environment for experimentation with scientific and engineering data and for the production of publication-quality graphs and page layouts."
  • Available for Mac OS X and Windows.
  • Time-frequency spectrograms can be produced, manipulated and analyzed just as easily as any other scientific plot!


BSound2


  • General procedures for viewing and analyzing sound signals.
  • Procedures require Igor Pro v6.01 (v6.02B02a for native GUI)
  • Place the unzipped folder named 'BSound2 Procedures' inside the '/User Procedures' folder.
