Bullet proof way of exporting Protools a session that can be imported into any audio application.
1. Once the sound is ready to be exported, you must consolidate all the stray regions in every track. To do this, select each region to be exported in the edit window, and go to Edit->Consolidate Regions.
2. If you are working with mono sound, rename the consolidated region to what you want to save the sound as (like "sample") by double-clicking the region with the hand tool. If you are working with stereo, name both tracks the same, but add a .L and .R to the left and right tracks (sample.L and sample.R)
3. Select the region's) to be exported. Then, on the right side of the edit window, click the button that says "Audio" to bring up the Audio Regions pulldown. Go to "Export Selected as Files". Select a File format (.wav is good), and select 16-bit audio. If you are exporting stereo sound, select "Stereo from .L/.R", or select "Mono (1)" if your sound is mono. Do not select "Use Squeezer" unless you are exporting in 8-bit audio. Click the "Choose" button to select the destination directory, and click OK to export
4. Save your session and exit ProTools. The sound clip you exported can be loaded into any audio application.
BY the way, it is actually required by record labels and publishing companies for projects to be bounced to wave files for archiving purposes. This way, in 20 years, the files might still be able to be read by whatever technology exists at that time, and the position of the tracks in relation to each other won't be an issue.
5. But the quickest way is The OMF format, It takes practically no time to create and OMF File that can imported into just about audio application, no matter what the operating system is. So for you Protools users spending the extra cash to get the Digitranslater application, it will save you a lot of time and allow for more flexibility.
