mdsp spectrum-analysis Command¶

Usage: mdsp spectrum-analysis|sp [options]

perform spectrum analysis on a sound file @

Options:
 -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

 Examples:

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