Media Library

The media library is where you store and manage all the audio tracks for your station’s AutoDJ. This article covers uploading, processing, and organizing your tracks.

Upload tracks

Open your station and go to Media Library in the left sidebar.

To upload tracks, either:

• Drag and drop files directly onto the media library page.
• Click the upload area to open a file picker and select files.

You can upload multiple files at once.

Accepted formats

Both CBR and VBR encoded files are accepted. Maximum file size is 500 MB per file.

Tagging during upload

You can apply tags to tracks during the upload process. Tags help you organize and filter your library later when building playlists.

What happens after upload

Each track goes through a processing pipeline before it appears in your library. You’ll see a progress indicator for each file.

Processing steps

1. Upload: The file transfers directly from your browser to CloudRadio’s storage.
2. Metadata extraction: Title, artist, album, genre, year, BPM, duration, and bitrate are read from the file’s tags.
3. Loudness normalization: The track is analyzed and normalized to -14 LUFS with a true peak ceiling of -1 dBTP. This keeps volume consistent across your entire library. See Audio Processing for details.
4. Cue point detection: Leading and trailing silence is detected and cue-in/cue-out points are set automatically. This keeps transitions tight.
5. Waveform generation: A visual waveform is created for the media library and playlist editors.
6. Artwork extraction: Embedded cover art is extracted from the file. If none is found, CloudRadio attempts to find a match using the track’s artist and title.

When processing completes, the track appears in your library ready for use.

Format handling

CloudRadio preserves your audio quality wherever possible:

CloudRadio never upscales. A 128 kbps source stays at or below 128 kbps. See Bitrates and Codecs for why this matters.

Organize your library

Tags

Tags are the primary way to organize tracks. You can:

• Apply tags during upload.
• Add or edit tags on individual tracks from the media library.
• Filter the library view by tag.
• Use tags when building playlists to include or exclude groups of tracks.

Common tagging approaches:

• By genre: rock, jazz, electronic
• By energy: upbeat, chill, intense
• By time slot: morning, evening, late-night
• By content type: music, jingle, sweeper, promo

Metadata editing

Click any track in the library to view and edit its metadata: title, artist, album, genre, and year. These fields appear in your stream metadata and player displays.

Cue points

CloudRadio sets suggested cue-in and cue-out points based on silence detection. You can adjust these manually per track if the automatic detection doesn’t match your preference.

Storage

Your available storage depends on your plan:

Current storage usage appears in the dashboard and media library. You can free up space by deleting tracks you no longer need.
