External Wave Files


Linked or external audio files are imported into the Catalog List as they were captured. That is, each track is considered as an independent wave file. If captured together with video, the audio file will use the same filename with an added suffix to designate the track plus the file extension. For example, the related audio files for the video file MyClip.avi, would be MyClipA1.wav, MyClipA2.wav, etc.

Audio media files in the Catalog List may be listened to simply by pressing the play button for the respective file. If you would like, however, to hear the linked audio files while playing back the video you must bear in mind the following considerations:

·Incite Media Assistant, as an off-line logging tool, allows one channel of audio output. You can choose which channel you wish to use, but you can never hear more than this one selected channel at a time.  
·To assign a specific audio output channel you need to launch the External Wave Files window. From Incite Media Assistant's main toolbar, select Tools/External Wave Files. Output channels can be chosen by pressing the appropriate A# button.

·Besides choosing which of the outputs will be used (remember that only one channel can be selected), you can also determine in which windows (or areas of windows) audio can be heard. The External Wave Files window lets you activate or de-activate audio in a specific area.  


Creating Related Wave Files

Incite Media Assistant, when it loads a video media file, immediately begins searching for all related files (including external audio files). Regarding external audio files, it loads the video media file, exterior1.avi for example, and then looks for exterior1.A1.wav, exterior1.A2.wav, etc. up to a maximum of four audio files.

Usually these audio files are captured together with the video media file. However, it is possible to create "artificially" related wave files for video media simply by changing the file name of an audio file, making it match the name of the AVI. You could then convert the AVI file including the external files in the conversion.

Including Audio and External Wave Files in Conversion or the Make Movie Process

Under the AVI and QT converter windows, as well as in the AVI and QT Make Movie windows, you will find options that let you include or exclude audio streams or external audio wave file when creating a new media file. These options are located under the Audio tab of each respective window mentioned above. For more details on how these options are used see 3.4 The Converter Window: Audio Format and Audio Parameters (AVI & QT Only).


Tips & Notes

·Audio may also be included with a video media file as a stream. This type of sound will not appear as a separate audio file (i.e. an external, but linked Wav file) in the Catalog List as it was captured or created as an integral part of the video file. To see if a video file comes with audio, check the number of streams it has under Show Clip Info.  

·If Incite and Incite Media Assistant are installed on the same system, note that they cannot make simultaneous use of DigiSuite for audio playback. We recommend that you install a sound card and that it is configured as the preferred device under Control Panel/Multimedia (Audio tab). If not, you can easily disable Incite's use of the hardware using Incite's Disable Audio command (letting Incite Media Assistant access the hardware without having to close Incite).  

·When creating related wave files, if the audio file is shorter than the AVI file, then there will obviously be no sound at the end of the AVI. If the audio file is longer, conversion will cut the audio file to match the video file's duration.
