Scrolling and Zooming<\/h2>\n

While recording some sound, you have seen how the horizontal axis shows the time of the
\n recording, and the vertical axis shows the frequency of the pitch at any given time.<\/p>\n

Once your recording gets longer than a few seconds, you might want to choose which part of
\n the recording you currently see. This can be done with scrolling and zooming the visible time
\n range. Also, depending on the content that you are currently working with, you might want to
\n change the visible frequency range. In this section we will do both.<\/p>\n

\n<\/a>2.4.1.\u00a0Loading sample file<\/h3>\n<\/div>\n<\/div>\n<\/div>\n

Let’s load a sample file so that you can follow this tutorial and see exactly the same
\n screens as shown here . Click on Help<\/span> \u2192 Open sample file<\/span> and select the file \u201cA01_male_intervals.flac<\/span>\u201d<\/span>. <\/p>\n

After you have opened the file, click on the profile list and select the
\n \u201cQuickstart<\/span>\u201d<\/span>
\n <\/strong><\/span> profile again to ensure your view matches the following screenshots. Remember
\n that you can always restore the Quickstart<\/strong><\/span> or Factory Settings<\/strong><\/span> profiles if you want to return the program to the
\n initial state. Your screen should now look like this:<\/p>\n<\/p>\n

\n <\/p>\n

First, let’s listen to the file. Click on the play button on the toolbar <\/span><\/span> or press Space<\/strong><\/span> to start playback. You can
\n adjust the loudness on the output volume slider on the toolbar. Listen to the recording and
\n then press Space<\/strong><\/span> again when you are done to stop playback.<\/p>\n

In this sample, the singer is singing a triad consisting of three different musical
\n notes. Let’s zoom in to see precisely which notes those are, and how accurately the singer
\n was singing them.<\/p>\n<\/div>\n

\n<\/a>2.4.2.\u00a0Zoom in time<\/h3>\n<\/div>\n<\/div>\n<\/div>\n

Let’s examine the first sung note more closely.<\/p>\n

Press and hold the button of your trackpad or mouse, and move the pointer over the blue
\n pitch line. Notice how this moves the green time cursor line. The current time position is
\n displayed on the status bar at the bottom of the window, along with details about the
\n current pitch frequency and musical note at that point in time.<\/p>\n

Move the green time cursor line to be exactly at the time point “1.0 seconds”. Now click on the menu View<\/span> \u2192 Zoom in<\/span> or press the 1<\/strong><\/span> key to zoom in the current time range. Do this one more time. Now you should see something like this:<\/p>\n<\/p>\n

\n<\/a><\/p>\n
\n
\"Time<\/div>\n<\/div>\n

\n <\/p>\n

Besides using the menu command to zoom in, you can also move the pointer over the main window and use the two-finger scroll gesture on your trackpad, or the wheel on your mouse, to zoom in and out.<\/p>\n<\/div>\n

\n
\n
\n
\n

\n<\/a>2.4.3.\u00a0Zoom in frequency<\/h3>\n<\/div>\n<\/div>\n<\/div>\n

We have zoomed the time scale so that the first sung note is stretched out over most of
\n the visible time range. Now we want to zoom in the frequency range to see more details about
\n the sung pitch on the frequency axis.<\/p>\n

Move the pointer over the Frequency Scale just to the right of the piano keyboard. When
\n pointing at the Frequency Scale, a grey horizontal line appears as a visual aid. Move the
\n pointer so that the grey line is approximately matching the blue pitch line, and then use
\n the two-finger scroll gesture on your trackpad, or rotate the wheel on your mouse, or press
\n the 1<\/strong><\/span> and 2<\/strong><\/span> keys on your keyboard, to zoom in the visible
\n frequency range to go approximately from notes A2 to A3 on the Piano, or 110 Hz to 220 Hz on
\n the Frequency Scale:<\/p>\n<\/p>\n

\n<\/a><\/p>\n
\n
\"Frequency<\/div>\n<\/div>\n

\n <\/p>\n

Notice how the blue line is not straight, but is slightly moving up and down. This is
\n due to the vibrato of the singing voice. Also, it looks like the pitch is rising slightly
\n throughout the duration of the note. VoceVista Video Pro<\/span> offers many ways to analyze this in
\n more detail, but for now we will continue with the fundamentals of using the program.<\/p>\n<\/div>\n

\n<\/a>2.4.4.\u00a0Scroll visible time range<\/h3>\n<\/div>\n<\/div>\n<\/div>\n

Now let’s look at other parts of the recording. Move the pointer over the center of the
\n Time-Range Slider on the Timeline until it changes into a hand. Then click and drag this slider with the mouse until the second note has been scrolled into view:<\/p>\n<\/p>\n

\n<\/a><\/p>\n
\n
\"Move<\/div>\n<\/div>\n

Figure\u00a02.12.\u00a0Move the Time Range Slider with the mouse<\/b><\/p>\n<\/div>\n


\n <\/p>\n

Another way to scroll time is simply to click anywhere on the Timeline to move the
\n current range to that position. Try that now: Move the pointer over the Timeline, at around
\n 4.5 seconds, and make a single click. This should move the time range to cover the third
\n note. However, now the pitch of the third note is no longer in view. So point at the
\n Frequency Scale and drag it down a bit until the pitch line is in view again:<\/p>\n<\/p>\n

\n <\/p>\n

So far we have set the visible ranges on the time and frequency axes by simply scrolling
\n and zooming those axes with the mouse, and by interacting with the Timeline. If you want to
\n set a specific frequency range, you can use the Frequency Scale Settings<\/a>. To set a specific time range, you can click on the menu Edit<\/span> \u2192 Set Selection<\/span> to select a specific time range, and then click on View<\/span> \u2192 Zoom to Fit Selection<\/span>.<\/p>\n<\/div>\n<\/div>\n
