mdsp spectrum-analysis


mdsp spectrum-analysis --help

Alternative form:

mc spectrum-analysis

(The CLI was using mc as default command name in older versions)


perform spectrum analysis on a sound file @


Parameter list:

Usage: mc spectrum-analysis|sp [options]

perform spectrum analysis on a sound file @

  -f, --file                             wav file to upload or json to analyze (default for threshold detection: fft.spectrum.json)
  -m, --mode [fft|threshold]                           Fast Fourier Transformation or threshold detection (default: "fft")
  -t, --thresholds                     threshold json for threshold detection (default: "thresholds.spectrum.json")
  -t, --output                                output file (fft: fft.spectrum.json, threshold: violations.spectrum.json)
  -w, --windowtype [flattop|hamming|hanning|blackman]  window type for the FFT (default: "flattop")
  -y, --retry                                  retry attempts before giving up (default: "3")
  -p, --passkey                               passkey
  -v, --verbose                                        verbose output
  -h, --help                                           display help for command


Here are some examples of how to use the mdsp spectrum-analysis command:


    mc spectrum-analysis -f machine.wav  	 Decomposes the sound file into frequency components
    mc spectrum-analysis -f machine.wav --windowtype blackman 	 use blackman window type for FFT preprocessing
    mc spectrum-analysis --mode threshold 	 detect threshold violations for thresholds stored in thresholds.spectrum.json
