Features

Built for Standardized Measurement: SignalScope's Room Acoustics Analyzer computes room acoustics parameters from impulse response data as specified in ISO 3382, Acoustics - Measurement of room acoustics parameters. It employs real-time Order 3 digital Butterworth bandpass filters, in whole or 1/3-octave frequency bands, designed with standard filter characteristics defined by ANSI S1.11 and IEC 61260.

Save Data: Export impulse response (IR) data to an audio file (.wav, .aif, or .caf) or IR data, calculated room acoustics parameter values, and metadata to a data file (.csv, .mat, or .txt). Or, generate a high-resolution image of the graph and save it to a PDF file.
