Find best Spectral Estimation Method for a Power Spectral Density plot. A menu of 10+ spectral estimators from Steve Kay's textbook 'Modern Spectral Estimation' 1988 is available to choose from. The results differ dramatically from one estimator to another. Plus, varying input parameters and/or number of points may provide discrepancies.

See how zero padding effects your results. Manufacturing companies take note! Some estimators can detect signals 50 to 100 dB from main signal. See documented example! The unwritten rule of '30 dB is okay' (i.e. hidden) is no longer true.

• Audio Spectrum Analyzer - OscilloMeter 6.07
  Multi-channel Audio Spectrum Analyzer is a set of Real-Time Multi-Channel Gauges for investigation of data accepted from any ADC you will want or 16-, 24- and 32-bit ADC of sound card

• CwGet 1.
  CwGet is a morse decoder which allows you to receive morse codes via your sound card. The program displays the spectrum of the current signal (blue line) and the peak detector of spectral components (green line). The vertical red line represents the working frequency of the filter. The 'AFC' (Automatic Frequency...
