Simplyfiying testing times

The Voyager merges multiple functional units like data acquisition, data storage and signal conditioning into a sleek tablet device. Embedded software with touchscreen response allows a more intuitive and user friendly operation for real-time audio playback and comprehensive analysis of the acquired data. Besides conventional FFT and octave frequency analyses, the implementation of


spectrogram analysis allows the user to also study non-stationary or transient noises. Targeted analysis with the help of real-time filters on a data channel optimizes the workflow and efficiency of the Voyager. The possibility of extension up to 6 channels allows autonomous measurement with reference microphones or accelerometers to correlate and compare data measurements.
