DADiSP / Octave 1/N Octave Analysis Module is released

Adept Scientific plc (Letchworth, Herts) is pleased to announce the addition of DADiSP/Octave from DSP Development Corporation (Newton, MA) to its range.

DADiSP/Octave 1/N is a menu driven module designed to simplify the task of octave, 1/3 octave and 1/N octave analysis used to characterise 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 normalised 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 dialogue box interface.
