This section describes the editing features of the Audio Editor Interface in detail. The Audio Editor Interface can be used to perform precise editing on audio data. Editing features that are discussed in this section include the cut, copy, paste and delete operations of audio as well as creating Extended Audio Snippets and Audio Loops from the audio data currently loaded into the Audio Editor Interface. Much of the information in this section expects that the user is familiar with the waveform navigating techniques of highlighting audio and using markers. These topics are covered in Section 6: The Audio Editor Interface in Detail.

  • Overview of the Editing Operations Multitrack Plus Audio Editor

    Whenever creating a professional audio production the topic of editing audio waveforms will be something of concern. The most common editing features allow the user to cut, copy and paste various sections of audio. The Audio Editor Interface of the Acoustic Labs Multitrack Plus fully supports these features which can be accessed via the pull down menu system by selecting the "Edit" pull down menu. To the right is a visual aid that shows the "Edit" pull down menu activated and displays the various editing features available. Note that at anytime you can remove the audio that is currently being edited by selecting the "Clear Current Audio" option located at the bottom of the list. The following topics in this section discuss the other editing options available in full detail.










    Cut, Copy, Paste and Delete Operations

    The most common editing features used when editing audio are the cut, copy and paste operations. When performing a cut operation the selected portion of audio will be removed from the track and placed on the audio clipboard. The audio clipboard is explained in more detail below. There are two different ways to perform a cut operation. By highlighting a section of audio and selecting the "Cut Highlighted Section" option from the "Edit" pulldown menu the highlighted section of audio will be removed and copied to the audio clipboard. The second method of cutting audio from a project is to set begin and end marker positions within the waveform and select "Cut Between Markers" from the "Edit" pull down menu. This will remove the audio located between the two markers and place it on the audio clipboard.

    The copy feature can be used to copy a selected section of audio from a track. This copied audio section will be placed on the audio clipboard. The steps involved in copying a section of audio are similar to that of cutting a section of audio as described above. There are two different ways to perform the copy operation. By highlighting a section of audio and selecting the "Copy Highlighted Section" option from the "Edit" pull down menu the highlighted section of audio will be copied to the audio clipboard. The second method to copy audio contained in a project is to set begin and end marker positions within the waveform and select "Copy Between Markers" from the "Edit" pull down menu. This will copy the audio located between the two markers to the audio clipboard.

    The audio clipboard is essentially a section of audio that is stored in memory. You cannot view what is currently contained on the audio clipboard, however the audio clipboard will always contains the audio data from the previous cut or copy operation. When you initially start the Acoustic Labs Multitrack Plus the audio clipboard will be blank. At anytime you can paste the contents of the audio clipboard to any position by using any one of the three paste operations. The three paste operations are "Paste Insert", "Paste Over" and "Paste Mix". The paste insert operation will insert the clipboard audio at the current position of the tracking bar. For more information on the tracking bar please see Section 6: The Audio Editor Interface in Detail. The paste insert operation can be selected from two different areas. First, using the top toolbar (visual aid item #2) you can simply click the "Paste" button. The other option is to select the "Paste Insert" option from the "Edit" pull down menu. Either option will perform the same paste insert operation.

    The "Paste Over" option can be accessed from the "Edit" pull down menu. The paste over feature works similarly to the paste insert feature except that instead of inserting, the clipboard audio will be placed over any existing audio - thus replacing it. As with the paste insert operation, the paste over operation will place the clipboard audio at the current position of the tracking bar. The final paste operation is the "Paste Mix" operation. This operation works similarly to the "Paste Over" operation except that instead of replacing the existing audio, it is mixed with the clipboard audio. When selecting this option a dialog box appears allowing you to choose the levels of the existing audio and the clipboard audio that will be pasted.



    Audio Properties

    Selecting the "Audio Properties" option from the "Edit" pulldown menu will display information concerning the audio data that you are currently editing. If you are currently editing an Extended Audio Snippet it will display a set of information specific to this audio snippet such as the unique ID of the snippet and the tempo. If you are editing an Audio Loop, information specific to the Audio Loop will be displayed such as the description, number of measures, tempo and length. No audio property information exists for independent audio.



    Creating Track Snippets and Audio Loops

    At anytime while editing audio data loaded into the Audio Editor Interface you can import the audio data as an Extended Audio Snippet into the Track View Interface or create an Audio Loop from the audio data. The menu options for accomplishing this are "Create Track Snippet" and "Create Audio Loop". When creating a new Extended Audio Snippet to be imported into the Track View Interface a dialog box will appear that allows you to select which track you wish to import the Audio Snippet to and at which time position. After clicking "OK" the new Extended Audio Snippet is created. To create a new Audio Loop based on the audio data loaded in the Audio Editor Interface simply select the "Create Audio Loop" option from the "Edit" pulldown menu. Doing so will instantly create the new Audio Loop in the Loop Bank Interface. The new Audio Loop will be added to the end of the list of Audio Loops in the Loop Bank and will have the description "Via Audio Editor".
