An exception to the workflow spelled out in Most Content is the Rohlig audio. We digitize the master, create derivatives for Mary Alice Fields, who then listens to them and determines which sections should be omitted and creates metadata. When her contribution returns, we create an MP3 for each track specified. These MP3s need to be uploaded with the MODS and distributed in Acumen. OCR of transcripts is handled by the makeJpegs script.


Rohlig Workflow

1. Digitize reels into master WAV files on local computer.


2. Use Sound Forge to optimize master WAV files; upload copy of optimized WAV files to share drive.

         Remove non-native silence
         Leave (or create if needed) 2 seconds of leading silence before each track


3. Make MP3 versions of WAV files using Lame. Burn MP3 files to cd and send to MAF, who then uses the cd to create metadata (including track timecodes) on a shared Excel sheet.


4. Copy metadata from MAF’s shared Excel sheet and paste to appropriate cells (changing format as needed) in main metadata Excel sheet.


5. Provide Metadata to Metadata Librarian for remediation.


6. Use MAF’s metadata to create a TXT file of track timecodes. Place TXT file into the Cue INPUT folder.


7. Use Cue_GUI to run the CueMaker and CueSplitter scripts for each item. (The scripts will level the the master WAV file's volume, create a CUE file, use the CUE file to split the master WAV file into sub-item tracks, convert the tracks from WAV to MP3 format, and save the resulting files to the Cue OUTPUT folder while naming them appropriately.)


8. Create MODS using Archivist Utility (use m02 template).


9. If we have transcripts, run makeAudioJpegs script to create JPEGs.


10. Run findMissing QC script.


11. Run relocate_audio script to upload MP3s, JPEGs, and MODS into Acumen.


12. Run moveAudioContent script to archive master WAV files, MODS, and CUE files.
