RecordingImporting music and sound ► Importing OMF projects

With OMFI (Open Media Framework Interchange) support & Broadcast WAVE support SONAR lets you collaborate and exchange project files with users of other programs and platforms. Support for OMFI and Broadcast Wave files provides cross-platform compatibility with OMFI host applications such as Pro Tools, Avid and Logic systems. SONAR also exports projects as OMF files that you can open in Pro Tools and other audio software.
SONAR allows you to select sample rate and bit depth during OMF import.
The OMF format, or OMFI (Open Media Framework Interchange, means the same as OMF), is a file format that can be read by many professional-level audio programs. OMF files contain two basic types of information:
list-image
Clip positions—an OMF file's EDL edit resolution can be either frame accurate or sample accurate. SONAR can read either, but always writes sample accurate. The clip position is specified in absolute samples.
list-image
Fades and crossfades (as destructive edits)—SONAR renders any fades when it writes OMFs, creating separate clips for any fade-ins or fade-outs. SONAR slip-edits the original clip to make room for the fade-in and fade-out clips. If you export to an audio program that supports slip editing, the user can delete the fade clips and roll out the original clip to return to the original raw audio (without fades) if desired.
list-image
Volume and pan envelopes—OMF does actually support limited automation. However, as with Nuendo and most other OMF host programs, gains and pans are ignored (on both read and write) in SONAR as they are only supported on MONO tracks (OMF limitation).
Whoever supplies the OMF file that you want to open in SONAR should also send along a text file containing all pertinent information about the project, especially tempo.
1.
Use the File > Open command, which opens the Open dialog box.
2.
In the Files Of Type field, select OMF File.
3.
Navigate to the folder that contains your OMF files, select the OMF file you want to open, and then click the Open button, which opens the Unpack OMF dialog box.
4.
If you know the exact tempo of the file, enter it into the Initial Tempo field. It is always preferable to know and enter the project tempo at this point. If you don't know the project tempo you can open the file at the default tempo and then change the file's tempo later, but this will cause the clips to move.
5.
The Sample Rate field displays the sample rate of the imported audio (if the audio is embedded in the OMF). Use this field to change the sample rate, if you need to.
6.
The Bit Depth field displays the bit depth of the imported audio if the audio is embedded. If the audio is external, the Bit Depth field defaults to the Original menu option, which will import the audio at the bit depth the audio is currently using. If you want to import the audio at a different bit depth, you can choose the bit depth in this field.
7.
If you have previously enabled SONAR's Use Per-Project Audio Folders option in Edit > Preferences > File - Audio Data, then the Store Project Audio In Its Own Folder check box is already enabled, and the fields under it are available. If you want to use this option, fill out the fields below the check box; otherwise, disable the check box.
8.
SONAR opens the OMF file.
You can also export SONAR projects as OMF files (File > Export > OMF command).
