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.

Track responses include read-only transcription and transcription_language (both null until a transcription output preset succeeds). Do not send these fields on create or update. GET /v1/track/:id does not include downloadable output URLs — use a play session, URL signing, or webhooks for file access. For per-output processing state, use GET /v1/track/:id/processing. Walkthrough: Voice & transcription.

DELETE /v1/track/:track_id
