Editing Multichannel Audio
With Sound Forge® Pro software, you can edit multichannel audio files in the same way you work with mono or stereo files.
Sound Forge software supports multichannel files in the following formats:
• Dolby AC-3 (.ac3) (AC-3 is available as a render format only)
• Raw Audio (.raw)
• Sony AVC (.mp4, .m2ts, .avc)
• Sony Wave64 (.w64)
• Wave (.wav)
• Video For Windows (.avi) – specifically DV, SDI
• Windows Media Audio/Video (.wma or .wmv)
• ATRAC (.oma)
• Material Exchange Format (.mxf)
Note:
MXF files require a video stream. If you want to save an audio-only file to MXF format, you must first attach a video stream. For
more information, see Attaching video to an audio file on page 276.
When working with MXF files, the number of channels in your source media must match the number of output channels specified by the
rendering template. If necessary, use the Channel Converter before rendering.
Render format Number of channels
DV MXF Always contains 4 audio channels.
You can use the Channels drop-down list on the Audio tab of the Custom Template dialog to choose how
many channels will be filled with audio. For example, if you choose 2 from the Channels drop-down list, the
rendered file will contain 4 audio channels: two channels will contain audio, and two channels will contain
silence.
IMX MXF Always contains 8 audio channels.
You can use the Channels drop-down list on the Audio tab of the Custom Template dialog to choose how
many channels will be filled with audio. For example, if you choose 2 from the Channels drop-down list, the
rendered file will contain 8 audio channels: two channels will contain audio, and six channels will contain
silence.
HD MXF Can contain 2 or 4 audio channels.
You can use the Channels drop-down list on the Audio tab of the Custom Template dialog to choose how
many channels will be rendered. For example, if you choose 2 from the Channels drop-down list, the
rendered file will contain only 2 audio channels.
