DADiSP/Octave is a menu driven module designed to simplify the task of octave, 1/3 octave and 1/N octave analysis used to characterize acoustic energy in a wide variety of applications.
DADiSP/Octave provides 1/N octave analysis using true IIR digital filters that conform to ANSI S1.11 and IEC 1260 specifications. A, B and C weighting filters can be applied to the input data. Output results include mean power, max power, min power and un-weighted RMS values. The output can be normalized with a calibration value. The results can be plotted on log or linear axes and exact or preferred frequency values are supported. All options can be specified through a straightforward dialog box interface.
See our DADiSP/Octave web pages for full information.
"DADiSP makes it possible for an engineer to hit the button to turn the program on at the end of the day, walk out of here, then come in the morning and find the work all done."
Rich Bond, Ford Heavy Truck
"DADiSP makes this kind of analysis very easy to do, so that I only have to worry about the science, not the programming."
Dr. Dan Davison, University of Houston
