The flexibility of noiseLAB Pro 4.0

noiseLAB 4.0 Data Flow

noiseLAB 4.0 consists of two programs

  • “noiseLAB Capture” for data acquisition, recording, and Editing
  • “noiseLAB Batch” for analysis of large batches of Recordings or edited Clips.

noiseLAB uses open data formats and can interface to a wide range of data types.


noiseLAB Capture accepts waveforms from:

  • National Instruments DSA Digitizers with IEPE transducer powering. This gives you plug-and-play configuration and a fully documented signal path.
  • Internal and external sound cards
  • .wav files from hard disk recorders, sound level meters, and other sources.
  • TDMS waveform files recorded by noiseLAB itself, or noiseLAB Wind. This gives you flexibility in analyzing files from other noiseLAB projects or noiseLAB Wind Recordings.

noiseLAB Capture can export waveforms in:

  • TMDS waveform format, with complete metadata annotation.  These files can be read by LabVIEW, Excel Plugins and others packages.  The format is fully documented by National Instruments.
  • .wav files.  Recordings or Clips from noiseLAB Capture can be output in scaled format to optimize dynamic range of the resulting files. The relative level of the individual files is retained.

noiseLAB Batch provides for advanced analysis (FFT, Octave, Tone or Impulse Analysis, Sound Quality, Vibration etc.) of multiple Recordings or Clips. Input data sources include:

  • Recordings from noiseLAB Capture
  • Recordings from noiseLAB 3.0
  • FFT Spectra for subsequent IEC 1996 Tone Analysis from
    • Delimited FFT files in a variety of formats
    • from noiseLAB 3.0
    • from noiseLAB Batch 4.0
    • noiseLAB Wind

noiseLAB Batch can output results as:

  • Tables of Results for each analysis type in delimited format easily parsed by Excel or other applictions.
  • jpg graphs of the result(s). For Time Slice analysis, graphs of multiple slices are automatically output in one operation.

This flexibility means noiseLAB makes it possible for you to interface to virtually any source of signals and output data in a range of popular and open formats.
