Spectrum analysis settings

You can change different aspects of the analysis by clicking the Settings... button:

The different settings are described below:

• Level scale

Selects how the analyzed levels are scaled.

• Block size (samples)

The duration of the time slices that are used create the spectrum (see Time and Frequency Domains for more information) in samples. The spectra from the analyzed time sliced are averaged to create the shown spectrum.

• Resolution (bins)

The number of curve points along the horizontal axis.

• Window attenuation (dB)

The attenuation in the analysis window specified in Decibels. Please see Time and Frequency Domains for details.

• Frequency scale

You can choose between different scales for the frequency axis: Linear, logarithmic or Mel scale. The latter is optimized according to our perception of sound.

• Minimum frequency (Hz)

The lowest frequency to show in the spectrum.

• Maximum frequency (Hz)

The highest frequency to show in the spectrum.

• Minimum level

The minimum level to show in the spectrum.

• Maximum level

The maximum level to show in the spectrum.
