Group source files with same BWF/iXML timecode in to takes
Add audio files to existing items as takes, if they have the same timecode stamp


Discuss the request in this thread

Premise
Sound for a show is recorded on multiple tracks, with the first track being a live downmix of the others.

The poly WAV, or multi-mono WAV files each have a timestamp, usually in the BWF chunk, and often in an iXML chunk(external recorders use that a lot). Often the "Sound Roll" field is utilized to keep recording days or sections apart too.

This downmix track is used by the video editors to cut the show, be it a documentary, music piece, film, tv show, interview or other stuff.




Problem
How to you get the other tracks in to this session without having to line everything up by hand ?

Video editors almost always use a single mono track, the downmix audio of the recordings, to cut the show. If the recordings came in as a multichannel WAV file(Poly WAV), the audio is often split in to multiple mono files before being used by the video editor.

Solution
Add other recorded tracks as takes to existing items.

The session from the video editor uses audio that has a timecode stamp, identical to the timecode stamp in the other mono WAV files. They may differ in filename, but the timecode stamps are identical. Often they also have a sound roll description as well, which makes it even easier to fine these files.

Reaper can do this like so :
  • The user selects the items for which other files should be added as takes.

  • Reaper checks the timestamps in selected items in the project bay or media explorer

  • The user is asked to point to directory with original recorder files that contains the other tracks, or perhaps ask the user to indicate which files should be scanned for the timecodes in the project bay. The user could prepare one project bay per sound roll for example.

  • Reaper compares timecodes and optionally sound roll fields("TAPE" field in the iXML description) in the BWF chunk and/or iXML chunk, and adds the files as takes to the relevant files with the correct offset and all.

  • Happy user.
