Exporting Audio Files
 
 
 

You can export audio from the current clip library to the filesystem as a multichannel audio file. This can be an audio-only clip or a video clip with audio. When you export audio, any uncommitted material is temporarily hard-committed (processed) and included in the exported file.

To export an audio file from a clip library:

  1. Open the clip library containing the audio that you want to export.
  2. Select the clip that contains the audio that you want to export.
  3. Click Export Audio.

    The Export Audio File menu appears.

  4. Use the browser to find the directory where you want to save the audio file.
  5. From the File Format box, select an audio file format.
  6. From the Sample Rate box, select the sample rate.
  7. Set the audio bit-depth using the Audio Bit-depth box.

    The available choices are: 16 bit, 24 bit, or 32 bit (float), depending on the file format selected. The default is 16 bits.

  8. Enter a name for the file in the Name field and press Enter.
    NoteTo avoid filename compatibility issues upon export, underscores will be substituted in your filename in place of any of the following characters: ` # ~ @ $ % ^ & * ( ) [ ] { } < > \ | / ! ? , ; : ' "
  9. If you are exporting MP3 files, set any of the available MP3 export options to be used for encoding.

    Bitrate Encoding Type boxSelect the type of bitrate encoding. Constant Bitrate encoding uses a single fixed bitrate for the entire file. Variable Bitrate encoding is a two-pass process of analyzing and then compressing movies to an optimal data rate. Average Bitrate encoding is similar to Variable Bitrate encoding except that it works within a set minimum and maximum bitrate.

    Quality boxSelect the quality of the encoding algorithm. This affects the speed of the encoding.

    VBR Quality boxSelect the number of bits used in the encoding as a factor of quality level. This affects the encoded file size.

    Bitrate boxSelect a bitrate value.

    Minimum Average Bitrate boxSelect the minimum bitrate to be used when Average Bitrate encoding is selected.

    Maximum Average Bitrate boxSelect the maximum bitrate to be used when Average Bitrate encoding is selected.

  10. If you are exporting a Broadcast Wave file, ensure that the timecode for the audio file does not start at a negative value (before 00:00:00:00).

    Broadcast Wave files do not support negative timecode values. If the timecode for your audio begins before 00:00:00:00 you will need to confirm that export can proceed starting only from 00:00:00:00. The section of audio in the negative timecode area will not be exported.

  11. Optional: Enable Apply AudioDesk.

    If you enable this option, the selected clip's AudioDesk settings are applied to the exported file. For instance, if you mix multiple tracks in an audio clip to stereo, you get two audio tracks (left and right panned) in the exported file. This process is equivalent to an audio mix down.

  12. Optional: Enable One File Per Track.

    When you enable this option, one file of the specified type is exported for each audio track. Each audio track is given a distinct filename (for example, Clip_track1.aiff, Clip_track2.aiff, and so on).

  13. Optional: Enable Apply In/Out Fades.

    If you enable this option, a short fade is added at the start and end of the audio clip. The length of the in/out fades can be set in the Audio Preferences panel via the Auto Fade slider. The length is from 0 to 10ms.

  14. Enable the audio tracks that you want to export in the Track Selection area.
  15. Click Export.

    The audio file is exported to the specified directory.
