Q. How can I timestamp audio files?

In Simon Price's recent series [Pro Tools Explained, SOS February‑April 2001], he mentioned that in order to transfer projects from Emagic's Logic sequencer to Pro Tools, you need to timestamp the file before transferring it. What are the exact steps you need to take in Logic to timestamp the audio files?


Simon Price replies: In addition to raw audio data, SDII‑format audio files (the format you'll need in this situation) can contain basic edit information; namely the 'in and out' points of regions used within the file, and their start locations within an arrangement. All audio files already have an 'original timestamp', which holds the start position where the file was recorded. In most cases, though, you edit and move audio around, so the original timestamp won't help if you want to spot audio into Pro Tools at the same position as it appeared in the Logic arrangement. To update an audio file with information about a contained region and its location (User Timestamp), select the region in Logic's Audio Window, and choose Export SDII Regions from the Audio File menu. The region can now be imported into a Pro Tools session, and spotted to the User Timestamp location. This method of transfer can be time–consuming and laborious for moving entire songs to Pro Tools, so it's more common to create continuous audio files for each track in Logic, and just use these. There will be much more detail regarding inter‑application transfers in an article I'm writing for a future issue of SOS.
