Creating a playlist#

A playlist contains all the sound files used in an experiment, stored as Section objects. The attributes of these sections can be edited in the admin interface or processed from a CSV file. These attributes can be used in your rules file to distinguish your sections for different purposes.

Each time the playlist is saved with Process csv checked, the sections are updated with the attributes from the Csv field.

CSV Format (comma separated):#

artist_name [string], song_name [string], start_position [float], duration [float], "path/filename.mp3" [string], tag [string], group [string]

Uploading sound files#

Uploading Sound files through the admin interface:#

  • Click Add playlist at localhost:8000/admin/section/playlist/ AdminOverview
  • Give your playlist a name. Note that this name will also be used to name the folder where the sound files will be stored on the server, so make sure this name is unique.
  • Leave the Csv field empty, Process Csv unchecked and click SAVE. Your playlist will now appear in the list when you click on “Playlists” on the left. PlaylistEmpty
  • Click Add sections next to your playlist. AddSection
  • You can add some attributes for your sections now, or leave these blank.
  • When either the artist or the name field is filled a Song object will be created for these sections.
  • The Tag and group attributes can be used as identifiers in your rules file. Add sections
  • Click Add sections to upload your files to the server and add the sections to the database.

Click on the name of your new playlist and notice that the Csv field is now filled with the attributes of the sections and the metadata of its sounds.

Manually uploading sound files#

When running a local MUSCLE development installation you can just create a folder with your sound files at backend/upload/

Running a production server you can use SSH or FTP to upload your sound files to a server, then adjust your apache / ngnx config to point to the location from which the sound files will be served.

Generate a CSV file:#

  • Run the compileplaylist command on your server container: docker-compose run --rm server ./manage.py compileplaylist <path-relative-to-upload-folder>. This will create a file named audiofiles.csv in the folder of your sound files.

  • Click Add playlist at localhost:8000/admin/section/playlist/ AdminOverview

  • Give your playlist a name
  • Paste the (edited) content of audiofiles.csv into the csv field.
  • Check Process Csv and click SAVE

This will create section objects for your sound files with the attributes from the CSV file.

Editing the section attributes#

Through the admin interface#

  • Click Edit sections at http://localhost:8000/admin/section/playlist/ ClickEditSections
  • Now you can alter the information of the sections in a table:

Through the Csv field:#
