Using Click Markers

Click markers are temporary soundmarks which can be placed anywhere in a soundfile and which may help to precisely localize disturbances (e.g., one can use a pair of click markers to 'frame' an extraneous sound).

Each time you set a click marker, an impulse is added to the sample at the cursor position (negative pulses are added if the sample value is positive and vice versa). Based on listening tests, you can adjust the amplitude of the pulse so as to make the resulting click audible but weak enough to prevent it from screening the disturbance you are trying to spot. Click markers are not permanent and do not corrupt the soundfiles they are added to - click pulses are kept in a separate buffer and injected only at the time of playing back the corresponding fragments. As a consequence, there is no need to remove click markers prior to closing or saving a soundfile. Click markers are distinguished by red vertical lines displayed in soundfile windows (along with the corresponding labels) and on the overview strip.Up to eight click markers, labelled A through H, can be associated with a single soundfile.

To set a click marker:

1. Position the cursor anywhere in an active soundfile window.

2. Select one of the eight marker labels. The list of all labels shows up when you click the Label arrow in the Set/Remove click markers dialog. Letters associated with the already existing markers are displayed with the 'tick' mark next to them. If you choose such a letter to label a new click marker, the previous one will be automatically removed. Each time you enter the Set/Remove click markers dialog, the first free label (if any) is shown in the Label box.

3. Press the PLAY button situated inside the dialog to play the fragment where the click marker will be inserted. If necessary, use the arrows in the Amplitude box to adjust the magnitude of the click. Use Play local from the Play menu to audition the same fragment without the click.

4. Click the Add button. The red click marker lines (temporarily hidden under the yellow cursor lines) will be added to the active soundfile and to the overview strip.

5. Press the Close button to close the Set/Remove click markers dialog.

In order to remove a click marker, proceed as above but instead of choosing the Addcommand in step 4, click the Remove button. If you want to remove all markers, use the Remove all button in the same dialog.

To move to the area where a given click marker was placed, open the Set/Remove click markers dialog, select the marker label and click on the Go to button. Alternatively, choose the Go to new position (G) command available from the Edit menu and type in ‘m’ followed by the marker label (e.g., after typing ‘ma’ you will jump to the click marker labeled A).

NOTICE

Click markers are not restored when the corresponding soundfile window is closed and opened again. However, you can save the current position of all click markers by saving a group of soundfiles (choose Save as from the Group menu).
