DELTA noiseLAB Express provides easy import, calibration, and analysis of .wav files recorded by a sound level meter or recorder. Third octave, fast Fourier transform (FFT), and sound level analysis to Type 1 standards can be performed. With the interactive Editor function, you can select relevant sections of the recording to quickly see, hear, and choose your signals by “scrubbing” the data.

This produces more accurate measurements, so you can perform additional analysis at a later time. noiseLAB Express is compatible with more advanced versions of noiseLAB for a broader range of analysis such as tone analysis and sound quality. These versions are also compatible with a variety of National Instruments dynamic signal analysis devices.

noiseLAB Express waveform files and results are stored in the NI Technical Data Management Streaming (TDMS) format for greater flexibility in post-processing. You can output result data to Excel as well.
