# Tracks | AudioDN Docs

> API endpoints for uploading, updating, listing, and deleting audio tracks. Manage track metadata, cover images, and player display settings.

# Tracks

Tracks are individual audio files within collections. Manage track metadata, uploads, playback information, and deletion.

Responses include two read-only companions to `player_color`: `player_color_light` (adjusted to stay legible on a light background) and `player_color_dark` (adjusted for a dark background). They are derived from `player_color` by shifting brightness until each meets a minimum contrast, so you can always render the player color on either theme. They cannot be set directly.
