Spectrogram & Spectrum<\/h2>\n

So far we’ve only looked at the pitch line, which shows the fundamental pitch of the
\n recording. Now let’s look at the Spectrogram, which shows how loud the recording is at
\n each point of the frequency range. Click on the Settings<\/strong><\/span>
\n button on the toolbar <\/span><\/span>, and then select Analyzer
\n View<\/strong><\/span> on the left, and Acoustic<\/strong><\/span> on the top, to
\n open the Analyzer View settings page<\/a>:<\/p>\n<\/p>\n

\n <\/p>\n

Check the Spectrogram<\/span> option on the left column, just under
\n Long-term view<\/span>. Then close the settings window.<\/p>\n

Now you should already see the Spectrogram, but the screen might still be zoomed in very
\n far from the previous step. On the toolbar, click on Settings Profiles<\/span>
\n and select the Standard Frequency Range <\/strong><\/span> profile. Then click
\n on View<\/span> \u2192 Zoom out fully<\/span>. Now your screen should look similar to this:<\/p>\n<\/p>\n

\n <\/p>\n

The colors on the spectrogram indicate the intensity of the sound for each frequency. In
\n other words, the spectrogram shows which frequencies are in the sound, and how loud they are.
\n To see this in more detail at any given point in time, we can enable the Short-term view<\/strong><\/span>, and in particular, the Spectrum<\/strong><\/span>. Reopen the Analyzer View settings
\n page<\/a> and check the Short-term view<\/span> and
\n Spectrum<\/span> options.<\/p>\n

Now the screen is split into two parts. The left side contains the Long-term view<\/strong><\/span>, which hows how the recording changes over time. The right side
\n contains the Short-term view<\/strong><\/span>, which shows details of the
\n recording at the specific point in time where the green time cursor line is located. Move the
\n pointer around over the spectrum with the mouse button held down, and observe how the spectrum
\n changes as you move the cursor to different time positions. Now move the green cursor line to
\n 8.0 seconds. <\/p>\n

Move the brightness slider on the toolbar (as shown on Figure\u00a02.3<\/a>) and see how the dynamic range of the spectrum and spectrogram
\n changes in response to that. Adjust the brightness slider so that all peaks on the spectrum
\n are fully visible. Then point at some of the spectral peaks on the right side and see how the
\n text display on the Short-term view shows the current frequency, nearest musical note, and
\n intensity, for each peak in the spectrum:<\/p>\n<\/p>\n

<\/p>\n

So now you can see the that the sound in our recording contains many individual frequency
\n components that have different levels of intensity. These are the harmonics. To better
\n understand what this means, let’s use another feature of VoceVista Video Pro<\/span>: the Frequency
\n Filter.<\/p>\n<\/div>\n
