Adding Metadata Columns to REAPER Media Explorer

All of the BWF audio files in Strata contain embedded metadata. All subproject files are configured to embed metadata for all audio file formats that REAPER supports.

You can view the metadata in the REAPER media explorer. However, you must add user columns to view and search the complete embedded metadata. Refer to Recommended User Columns for a list of metadata that might be useful.

To add columns to the REAPER media explorer:

  1. In the menu bar, click View > Media Explorer. The media explorer opens.

  2. Right-click any column header, then click Add user column. The Add Metadata Column dialog opens.

  3. In the Key text box, type one of the recommended user columns. For example, the ASWG:Category entry adds a category metadata column.

  4. In the Description text box, type an appropriate name, such as Category.

  5. Click OK. The column is now visible in the media explorer.

  6. In the media explorer, select the <Project Directory> in the folder hierarchy at the left of the window. The subproject files appear in the file list.

  7. Right-click one or more audio files and click Re-read metadata from media. The metadata appears in the new column for the selected files.

Recommended User Columns

In REAPER’s Render to File > Metadata window, you can see a complete list of all fields that you can add as user columns in the media explorer. Strata projects have ASWG, BWF, INFO, XMP, and IXML:USER metadata fields that can be embedded in .wav files.

The ASWG Schema supports embedding metadata in .wav, .flac, and .mp3 files, and includes fields specific to the UCS that are used in the Strata collection for all audio file names.

The following list of user columns is recommended for Strata users.
